Description

FIELD OF THE INVENTION

The present invention relates to novel ophthalmic devices comprising polymerized compounds comprising a photoactive chromophore, said polymerized compounds, and special monomer compounds being particularly suitable for compositions and ophthalmic devices. The present invention is also directed to a process of changing the optical properties of said ophthalmic device or a precursor article for manufacturing said ophthalmic device.

BACKGROUND OF THE INVENTION

Cataract is a general term for an affection of the eye that leads to a loss of vision and in the extreme to blindness by clouding of the normally clear lens of the eye. It is the major cause of blindness in the world, affecting more than 100 million people. Due to the fact that its major cause is age and the population's average age is increasing, it is expected that the number of cataracts will continue to increase substantially in the future.

Effective treatment of cataract is only possible by surgical intervention, whereby the natural lens of the eye is removed through an incision in the cornea and replaced with an ophthalmic device, often also referred to as “intraocular lens”. In preparation of surgery current state-of-the-art surgical methods employ eye mapping so as to approximate the refractive power best suited to the respective patient.

Even though cataract surgery is one of the most widely used and safest surgical procedures it is not without specific post-surgery problems. It frequently happens that the refractive power of the implanted intraocular lens (IOL) is insufficient for restoring good vision. Such problems may, for example, be caused by changes in eye geometry as consequence of the surgery as well as irregular wound healing and positioning errors that result in the ophthalmic device not having the optimal optical properties. As a result the patient will still require corrective vision aids, e.g. glasses, to be able to see correctly. In some cases the resulting refractive power of the implanted ophthalmic device is so far removed from the required refractive power that further surgery will be required. Particularly for aged persons this is not desirable because the body's capability for healing is reduced with increasing age. Furthermore, there is the risk of attracting endophthalmitis, an inflammation of the eye, which can even lead to a complete loss of vision or worse, loss of the eye.

There is therefore a need in the health sector for optically active ophthalmic devices, and particularly for artificial intraocular lenses, that would allow for non-invasive adjustment of refractive power after implantation of the lens, thereby preferably further reducing the need for post-surgery vision aids.

Some developments in this sense have already been made, as for example evidenced by WO 2007/033831, WO 2009/074520, US 2010/0324165, WO 2017/032442, WO 2017/032443, WO 2017/032444, WO 2018/149850, WO 2018/149852, WO 2018/149853, WO 2018/149855, WO 2018/149856 or WO 2018/149857.

However, there is still a need to provide alternative or improved ophthalmic devices e.g. contact lenses or lenses to be implanted by state of the art cataract surgical methods and there is still a need to provide special compounds for the manufacture of ophthalmic devices e.g. of intraocular lenses to be implanted by state of the art cataract surgical methods, particularly by state of the art micro-incision cataract surgical methods.

Consequently, it is an objective of the present application to provide for alternative or improved ophthalmic devices and suitable compounds for the manufacture of such ophthalmic devices.

It is also an objective of the present application to provide for compounds, the optical properties of which may be changed, preferably by non-invasive techniques.

It is a further objective of the present application to provide alternative compounds or compounds having advantages over currently known compounds, preferably in combination with being suitable for ophthalmic devices.

An advantage for the monomers of formula (I) to be used for the preparation of the ophthalmic device according to the invention is the better handling through low melting points by using them in compositions and or polymers/copolymers. A further advantage is that the liquid to low melting monomers of formula (I) to be used for the preparation of the ophthalmic device according to the invention enable a higher flexibility in the choice of initiators for a thermally activated polymerization.

Advantages for polymers or copolymers comprising polymerized monomers of formula (I) according to the invention are good flexibilities and low glass transition temperatures. The polymers or copolymers according to the invention preferably show a significant polarizability change or refractive index change after irradiation and partially increased higher refractive starting indices. The total value of refractive index change per mmol photoactive chromophore is much higher compared to prior art materials. This enables a higher flexibility in adjusting the polarizability or refractive index of the ophthalmic device according to the invention. Based on this advantage of the polymers or copolymers of the invention, the ophthalmic device comprising said materials can be manufactured thinner compared to ophthalmic devices comprising prior art materials.

DETAILED DESCRIPTION OF THE INVENTION

Compounds of formula (I) as described before or preferably described below can be preferably used as monomers for the preparation of a precursor article such as a blank which may be transformed to an ophthalmic device such as an eye-implant or specifically an intraocular lens or can be preferably used for the preparation of the ophthalmic device as such as described before or preferably described below.

The compounds of formula (I) and all preferred embodiments of compounds of formula (I) including any monomeric units according to the present invention include all stereoisomers or racemic mixtures.

The compounds of formula (I) provide several advantages over prior art materials for the preparation of ophthalmic devices or precursor articles for manufacturing an ophthalmic device as described before. Moreover, the addition of the nitrogen atom to the left aromatic part of the central chromophore in the compounds of formula (I) or oligomers, polymers and copolymers comprising polymerized compounds of formula (I) has a significant impact on the optical properties over prior art compounds as described before.

Polymers that are foldable at room temperature generally exhibit glass transition temperatures (T_g) lower than room temperature (ca. 21° C.). They are easily deformable at this temperature without causing physical damage to the polymer, for example by inducing creep, stress or fissures. For polymers in intraocular lenses, T_gs of less than or equal to 15° C. are preferred.

Polymers used in ophthalmic device manufacturing, preferably in intraocular lens manufacturing, have preferably relatively high refractive indices, which enable the fabrication of thinner ophthalmic devices such as intraocular lenses. Preferably, the polymer used in an ophthalmic device, preferably an intraocular lens, will have a refractive index greater than about 1.5 and presently most preferably greater than about 1.55.

In case an asterisk (“*”) is used within the description of the present invention, it denotes a linkage to an adjacent unit or group or, in case of a polymer, to an adjacent repeating unit or any other group whenever it is not specifically defined.

A linear or branched alkyl group having 1 to 10 C atoms denotes an alkyl group having 1, 2, 3, 4, 5, 6, 7, 8, 9 or 10 C atoms, for example methyl, ethyl, iso-propyl, n-propyl, iso-butyl, n-butyl, tert-butyl, n-pentyl, 1-, 2- or 3-methylbutyl, 1,1-, 1,2- or 2,2-dimethylpropyl, 1-ethylpropyl, n-hexyl, n-heptyl, n-octyl, ethylhexyl, n-nonyl or n-decyl.

As described before, the compounds/monomers of formulae (I), (I #), (I′), (I′-a), (I′-b), (I′-c), (I′-d), (I′-e), (I′-f), (I′-g), (I′-h), (I′-i) and (I″) as described before or preferably described before contain a polymerizable group and are predestinated as monomers for an oligomerization or a polymerization.

The invention is therefore further directed to an oligomer, polymer or copolymer comprising at least one polymerized compound of formulae (I), (I #), (I′), (I′-a), (I′-b), (I′-c), (I′-d), (I′-e), (I′-f), (I′-g), (I′-h), (I′-i) or (I″) as described before or preferably described before.

The term “polymer” generally means a molecule of high relative molecular mass, the structure of which essentially comprises the multiple repetition of units derived, actually or conceptually, from molecules of low relative molecular mass (PAC, 1996, 68, 2291). The term “polymer” includes homopolymers and copolymers if not mentioned otherwise within the description. The term “oligomer” generally means a molecule of intermediate relative molecular mass, the structure of which essentially comprises a small plurality of units derived, actually or conceptually, from molecules of lower relative molecular mass (PAC, 1996, 68, 2291). In a preferred sense according to the present invention a polymer means a compound having ≥30 repeating units, and an oligomer means a compound with >1 and <30 repeating units.

Above and below, in formulae showing a polymer, an oligomer, a compound of formulae (I), (I #), (I′), (I′-a), (I′-b), (I′-c), (I′-d), (I′-e), (I′-f), (I′-g), (I′-h), (I′-i) or (I″) or a monomeric unit or a polymer formed from a compound of formulae (I), (I #), (I′), (I′-a), (I′-b), (I′-c), (I′-d), (I′-e), (I′-f), (I′-g), (I′-h), (I′-i) or (I″), an asterisk (“*”) denotes a linkage to the adjacent repeating unit in the polymer chain or oligomer chain or to a terminal end group.

Suitable terminal end groups are known to the skilled artisan and depend on the polymerization method used.

The terms “repeating unit” and “monomeric unit” mean the constitutional repeating unit (CRU), which is the smallest constitutional unit the repetition of which constitutes a regular macromolecule, a regular oligomer molecule, a regular block or a regular chain (PAC, 1996, 68, 2291).

Unless stated otherwise, the molecular weight is given as the number average molecular weight Mn or weight average molecular weight Mw, which is determined by gel permeation chromatography (GPC) against polystyrene standards in eluent solvents such as tetrahydrofuran, trichloromethane (TCM, chloroform), chlorobenzene or 1,2,4-trichloro-benzene. Unless stated otherwise, tetrahydrofuran is used as solvent. The degree of polymerization (n) means the number average degree of polymerization given as n=Mn/Mu, wherein Mu is the molecular weight of the single repeating unit as described in J. M. G. Cowie, Polymers: Chemistry & Physics of Modern Materials, Blackie, Glasgow, 1991.

In the polymers including copolymers according to the present invention, the total number of repeating units n is preferably ≥30, very preferably ≥100, most preferably ≥200, and preferably up to 5000, very preferably up to 3000, most preferably up to 2000, including any combination of the aforementioned lower and upper limits of n.

Hence the ophthalmic device and the precursor article for manufacturing the ophthalmic device are sensitive to two-photon or multiphoton absorption.

The system for two-photon or multi-photon irradiating of the ophthalmic device according to the invention, preferably of an intraocular lens preferably arranged within an eye of a patient is not restricted. Some examples are described below.

Hence the present invention is also directed to precursor articles for manufacturing an ophthalmic device wherein said precursor article is a blank which may be transformed into optically active ophthalmic devices comprising at least one oligomer, polymer or copolymer as described before or preferably described before comprising one or more constitutional units M⁰ of formulae (M⁰-I′-a), (M⁰-I′-b), (M⁰-I′-c), (M⁰-I′-d), (M⁰-I′-e), (M⁰-I′-f), (M⁰-I′-g), (M⁰-I′-h), (M⁰-I′-i) or (M⁰-I″) or one or more constitutional units (M⁰-001) to (M⁰-162) as described before or preferably described before.

Preferred ophthalmic devices are optically active ophthalmic devices. Examples of such ophthalmic devices or eye-implants include lenses, keratoprostheses, and corneal inlays or rings. More preferably, said ophthalmic device or eye-implant is a lens article. Most preferably, such ophthalmic device is a lens. The type of lens is not restricted and may comprise a contact lens or an intraocular lens. Most preferably, such ophthalmic device is an intraocular lens, which may, for example, be a posterior chamber intraocular lens or an anterior chamber intraocular lens.

A blank of this invention may be produced as a step in the manufacturing process used to create an ophthalmic device as described before, preferably an intraocular lens. For example, without limitation, a manufacturing process may include the steps of polymer synthesis, polymer sheet casting, blank cutting, optic lathe cutting, optic milling, haptic milling or attachment, polishing, solvent extraction, sterilization and packaging while the term polymer is used as described before or preferably described before.

The present ophthalmic devices or the precursor articles for manufacturing an ophthalmic device according to the invention as described before or preferably described before may be formed by a process comprising the steps of

• • providing a composition comprising at least one compound of formulae (I), (I #), (I′), (I′-a), (I′-b), (I′-c), (I′-d), (I′-e), (I′-f), (I′-g), (I′-h), (I′-i) or (I″) or the compounds (A-001) to (A-162) as described herein or preferably described herein and/or an oligomer or polymer as described herein or preferably described herein but having at least one reactive group left for polymerization and optionally further monomers different from compounds of formulae (I), (I #), (I′), (I′-a), (I′-b), (I′-c), (I′-d), (I′-e), (I′-f), (I′-g), (I′-h), (I′-i) or (I″) or the compounds (A-001) to (A-162) as described herein or preferably described herein and/or crosslinking agents and/or UV absorbers and/or radical initiators; and
  • subsequently forming the ophthalmic device or the precursor article of said composition.

Intraocular lenses in accordance with the present invention are believed to show particularly advantageous properties in that they are flexible enough so as to be rolled or folded and consequently requiring a much smaller incision for them to be inserted into the eye. It is believed that this will allow for improved healing of the eye, particularly in respect to the time for the eye to heal.

The type of intraocular lens is not limited in any way. It may, for example, be a pseudo-phakic intraocular lens or a phakic intraocular lens. The former type replaces the eye's natural, crystalline lens, usually to replace a cataractous lens that has been removed. The latter type is used to supplement an existing lens and functions as a permanent corrective lens, which is implanted in the anterior or posterior chamber to correct refractive errors of the eye. It may, for example, comprise one or more optic and one or more haptic components, wherein the one or more optic components serve as lens and the one or more haptic components are attached to the one or more optic components and hold the one or more optic components in place in the eye. The present intraocular lens may be of a one-piece design or of multi-piece design, depending on whether the one or more optic components and the one or more haptic components are formed from a single piece of material (one-piece design) or are made separately and then combined (multi-piece design). The present intraocular lens is also designed in such a way that it allows to be, for example, rolled up or folded small enough so that it fits through an incision in the eye, said incision being as small as possible, for example, at most 3 mm in length.

Additionally, intraocular lenses in accordance with the present invention allow for the non-invasive adjustment of the optical properties, particularly the polarizability or the refractive power, after implantation of the lens into the eye, thus reducing the need for post-surgery vision aids or reducing or totally avoiding follow-up surgery.

In order to change the optical properties and particularly the polarizability or refractive power of the ophthalmic device according to the invention e.g. an intraocular lens it is exposed to irradiation having a wavelength of at least 200 nm and of at most 1500 nm. Said irradiation is not limited and may be a based on a single-photon or two- or multi-photon process.

Hence, the present invention is also directed to a process of changing the optical properties of an ophthalmic device or a precursor article for manufacturing an ophthalmic device as defined or preferably defined herein, said process comprising the steps of

• • providing an ophthalmic device or a precursor article for manufacturing an ophthalmic device as defined herein; and
  • subsequently exposing said ophthalmic device or said precursor article to irradiation having a wavelength of at least 200 nm and at most 1500 nm.

Preferably, said irradiation has a wavelength of at least 250 nm or 300 nm, more preferably of at least 350 nm, even more preferably of at least 400 nm, still even more preferably of at least 450 nm, and most preferably of at least 500 nm. Preferably, said irradiation has a wavelength of at most 1400 nm or 1300 nm or 1200 nm or 1100 nm or 1000 nm, more preferably of at most 950 nm or 900 nm, even more preferably of at most 850 nm, still even more preferably of at most 800 nm and most preferably of at most 750 nm.

Hence, the present invention is also directed to an ophthalmic device or a precursor article for manufacturing an ophthalmic device obtainable by said irradiation process as described before or preferably described before or below.

Alternatively, you may describe the change of refractive power as a modification of the index of refraction of said ophthalmic device as described before or preferably described before. Alternatively, you may describe the change of refractive power as a modification of the index of refraction of said intraocular lens as described before or preferably described before. Irradiation within the focal volume results in refractive optical structures characterized by a change in refractive index relative to the index of refraction of the bulk of said ophthalmic device or alternatively the non-irradiated portion of said ophthalmic device. Irradiation within the focal volume results in refractive optical structures characterized by a change in refractive index relative to the index of refraction of the bulk of said ophthalmic device or intraocular lens or alternatively the non-irradiated portion of said ophthalmic device or intraocular lens. The change in polarizability or refractive index can in other words be used to form patterned desired refractive structures in the optical ophthalmic device as described or preferably described before, preferably in the intraocular lens as described or preferably described before.

Hence, the present invention is also directed to an ophthalmic device obtainable by said irradiation process as described before or preferably described before and below having refractive optical structures characterized by a change in refractive index relative to the index of refraction of the bulk of said ophthalmic device or alternatively the non-irradiated portion of said ophthalmic device.

It is preferred to provide refractive structures that exhibit a change in refractive index, and exhibit little or no scattering loss in such a way that ablation or removal of the optical ophthalmic device, preferably the intraocular lens article is not observed in the irradiated region.

In such processes, the irradiated regions of the ophthalmic device as described before or preferably described before can take the form of two- or three-dimensional, area or volume filled refractive structures that can provide spherical, aspherical, toroidal, or cylindrical correction. In fact, any optical structure can be formed to yield power correction in both physical directions. Moreover, the optical structures can be stacked vertically or written in separate planes in the ophthalmic device as described before or preferably described before to act as a single lens element.

The invention is therefore further related to a method for locally adjusting a polarizability and/or a refractive index of an ophthalmic device according to the invention preferably an intraocular lens preferably arranged within an eye of a patient. The method relates in particular to fabrication of optical profiles by adjusting polarizability through two- or multi-photon processes in a non-destructive manner. Said two- or multi-photon processes allow for different optical profiles compared to single-photon processes and can be advantageously used for the manufacture of the ophthalmic devices according to the invention containing optical profiles.

The system to be used for said two- or multi-photon process advantageously allows for post-operative and non-invasive adjustment of optical properties/profiles of an implanted intraocular lens (IOL) to remove visual impairments such as refractive errors. Furthermore, when manufacturing the ophthalmic device according to the invention, the system advantageously allows for a gentle preparation of the ophthalmic device so as to in particular allow for refractive structures that can provide spherical, aspherical, toroidal, or cylindrical correction and/or maintaining flexibility of the ophthalmic device once preparation of the ophthalmic device is completed. The polarizability of the ophthalmic device is modified based on a two-photon (or generally multi-photon) process which allows adjustment of optical properties/profiles of said ophthalmic device or which allows adjustment of optical properties in different planes of the ophthalmic device. Furthermore, the modification of polarizability based on a two-photon or multi-photon process allows for improved maintaining of flexibility of the ophthalmic device when treated with wavelength of 400 nm to 590 nm.

Therefore, the invention further relates to a process for adjusting a polarizability of an ophthalmic device according to the invention based on a two- or multi-photon absorption process, the process comprising the steps of:

providing said ophthalmic device as described before or preferably described before; and

adjusting the polarizability of said ophthalmic device through irradiation of said ophthalmic device by using a system,

said system comprising:

• • one or more irradiation sources for two-photon or multi-photon irradiating a said ophthalmic device with an irradiation beam focused with an optic and of a first wavelength and/or a second wavelength different from the first wavelength,
  • a scanner coupled to the one or more irradiation sources and configured to scan a said irradiation beam across said ophthalmic device, and
  • an input unit coupled to the one or more irradiation sources and the scanner, wherein the input unit is configured to input data for treating said ophthalmic device by scanning a said irradiation beam across said ophthalmic device based on the input data, and
    • wherein the first wavelength is between 600 nm and 800 nm for locally decreasing, based on said treating of said ophthalmic device, a polarizability of said ophthalmic device, and wherein the second wavelength is between 400 nm and 590 nm for locally increasing, based on said treating of said ophthalmic device, the polarizability of said ophthalmic device and thereupon changing the polymeric optical material of said ophthalmic device, preferably with significant differences in the UV/Vis spectrum with respect to the non-irradiated polymeric optical material of the ophthalmic device.

Ultraviolet-visible spectroscopy or ultraviolet-visible spectrophotometry (UV-Vis or UV/Vis) is known to a person skilled in the art. It refers to absorption spectroscopy or reflectance spectroscopy in part of the ultraviolet and the full, adjacent visible spectral regions. Suitable UV/Vis spectrometers are commercially available. The choice of the UV/Vis spectrometer is not critical for the comparison of the UV/Vis spectrum of the initial ophthalmic device and the UV/Vis spectrum of said irradiated ophthalmic device to be made according to the present invention. As long as both measurements are made under comparable conditions so that the results can be compared which is known to the person skilled in the art. A suitable spectrometer is the UV/Vis spectrometer Lambda 900 from Perkin Elmer.

The polarizability may hereby be locally changed particularly precisely.

The invention is furthermore related to a method for correcting vision in a patient by modifying the refractive index of an intraocular lens within the eye of said patient comprising

• • identifying and measuring the degree of vision correction of the patient;
  • determining the position and type of refractive structures to be written into said intraocular lens to correct the patient's vision; and
  • subsequently exposing said intraocular lens to two-photon or multi-photon irradiation having a wavelength between 600 nm and 800 nm to locally decrease the polarizability of the intraocular lens or exposing said intraocular lens or

subsequently exposing said intraocular lens to two-photon or multi-photon irradiation having a wavelength between 400 nm and 590 nm to locally increase the polarizability of the intraocular lens.

In the present application, input data are all kinds of data used for creating the treatment plan which is defined as the translation of the ophthalmic need into control commands for the writing process of the ophthalmic device according to the invention. During the writing process the optical pattern is written by irradiation in said ophthalmic device.

The term “control commands” refers to commands directly controlling the process of writing as defined before. A control command may control e.g. the movement of the scanner.

The term “scanner” used within the description is not part of the input unit according to the invention. The “scanner” as described herein is a component of the system to be used in the process for adjusting a polarizability of an ophthalmic device according to the invention which controls the movement of the irradiation beam.

The ophthalmic need refers to the desired optical profile which has to be created in the ophthalmic device through the system as described.

The optical profile is the needed change defined by the surgeon according to the patient's examination results before or after the ophthalmic device, preferably the intraocular lens is implanted; for example but not limiting to a spherical full diopter change, a toric profile, an EDOF profile or a bi-, tri- or multifocal profile. Alternatively, the optical profile is the optical property adjustment of the ophthalmic device.

The optical pattern is the necessary change of polarizability resulting in change of refractive index in every voxel of the ophthalmic device.

The term “optic” as used herein as a part of the system to be used in the process for adjusting a polarizability of an ophthalmic device according to the invention includes all optical equipment necessary to control the spatial distribution of the irradiation source (focus) on the ophthalmic device. Critical parameters of the focus include the lateral focus size (or beam waist) and the focus length (or Rayleigh range). The optic comprises all elements along the optical beam path that determine the focus, such as beam expanders, aperture stops, shutter and in particular the focusing optics, such as a microscope objective or a single aspherical lens.

Multi-photon excitation occurs only in the vicinity of the focal point and preferably by employing ultra-short laser pulses. The average power is limited by the sample damage threshold such threshold being part of the input data as defined before.

Criteria for the selection and optimization of system parameters: One ultimate purpose is to generate localized refractive-index modification of IOLs post-implantation as prescribed by the physician to improve the visual acuity of the patient. A crucial criterion for the procedure of refractive-index modification is the total treatment time required to obtain the desired result. It is generally recognized that such procedure should not take more than a few minutes in order to be recognized as viable. The systems capable of localized refractive-index modifications of the state of the art do not include an approach to obtain practical treatment times for IOL applications.

Discussion of System Tradeoffs and Limitations:

For a practical high-performing system capable of adjusting ophthalmic devices in general or specifically IOLs after implantation it is recognized that its subcomponents have to be treated as a system and must therefore be optimized jointly as many interdependencies and tradeoffs between the subcomponents exist. The subcomponents include the irradiation source, the optic, the scanner and treatment plan.

A key requirement of any system/parameter optimization is to stay within safe limits for the ophthalmic device material in case of the treatment or the material and the eye with its components (e.g. retina) in case of the treatment of an ophthalmic device being an IOL. Such requirements build the basis for input data as described before. In particular, two main damage mechanisms for radiation from an irradiation source, preferably a pulsed laser source can be distinguished: Single-pulse damage (dielectric breakdown and avalanche breakdown), and thermal damage, where the temperature of the lens material and/or the eye is heated up subsequently for repeated pulses to the same volume. For example: the average power of a pulsed irradiation source relates to the heating and therefore to the potential damage of the lens material and/or the eye. Therefore, while keeping the average power of the irradiation source below the threshold of overheating the lens material and/or eye, pulse energy and pulse repetition rate are inversely related product of pulse energy and number of pulses per second (=inverse of repetition rate) is equal to the average power.

Average power is defined as pulse energy multiplied by number of pulses per second) and is characterized by Watt (W).

Irradiance is equal to flux density) (W/cm²).

Radiant exposure is equal to fluence) (J/cm²).

One overall objective is to minimize the treatment time for an IOL adjustment after implantation. In theory, higher and higher pulse energies with more frequent pulses (=higher repetition rate) could be applied, however, above an average power of typically 1 Watt, overheating starts creating unsafe conditions for IOL material and retina. Therefore, in order to stay within safe operating limits, while completing a treatment of the full IOL volume in a few minutes, one can define a preferred radiant exposure. The preferred radiant exposure is ≤5 kJ/cm², particular preferably <1 kJ/cm² and very particular preferably <0.3 kJ/cm². This described radiant exposure applies additionally to the processes and methods according to the invention as further described below.

For the case a treatment plan is too extensive and would exceed the limits of laser safety concerning overheating, it is possible to interrupt the treatment to allow a cool down of all by the treatment affected ophthalmic device material and tissues. After the cool-down the locating system can compare the treated voxel in the ophthalmic device with the optical pattern and the treatment can be continued.

The process of adjustment of optical properties/profiles of said ophthalmic device through the system and with requirements as described before will be done according to a treatment plan as described before. According to a treatment plan, profiles for e.g. toric, spheric, multifocal or EDOF (extended depth of focus) can be written into the ophthalmic device according to the invention. An algorithm may be utilized to write in profiles for e.g. toric, spheric, multifocal or EDOF (extended depth of focus) profiles.

By combining the information of the desired optical profile together with the input data, the needed optical pattern and the control commands for irradiation source, optics and scanner of the system as described before can be calculated. Further input data are for example lens data as such as the needed laser-energy for a certain refractive index change per voxel of said ophthalmic device material, and further patient data as the exact position and orientation of the ophthalmic device in the patient's eye being part of the treatment plan data.

The control commands can be updated and modified during the writing process by in-process input data such as temperature data of the patient's eye by e.g. IR-temperature measurements, in-process positioning data of the irradiation beam, the ophthalmic device or the eye acquired for example by OCT (optical coherence tomography) and/or refractive data acquired from Scheimpflug images.

In a further embodiment of input data, the input data comprises lens data of said ophthalmic device preferably of said intraocular lens and/or treatment plan data relating to a treatment plan for said treating of said ophthalmic device. For example, the lens data may comprise data relating to one or more of the polarizability and/or refractive index of the ophthalmic device as a function of the location of a respective volume or part of the ophthalmic device, shape, diopter, cylinder and sphere and/or its individual aberrations in said dimensions. The polarizability may therefore be increased or decreased at a particular location or volume in one or more planes of the ophthalmic device depending on the current polarizability (or refractive index) and the polarizability (or refractive index) to be obtained via the treatment.

The treatment plan calculation may, in some examples, generate control commands resulting in one or more of treatment plan data comprising: scan strategy control command data of a scan strategy (for example a scanning pattern and/or a scanning sequence and/or a scanning speed and/or a scanning duration of the scanning pattern and/or a scanning duration of the scanning sequence and/or a pulse duration of a pulse of the irradiation beam of the first and/or second wavelength (for example, nanosecond or picosecond or femtosecond pulses) and/or an irradiation beam profile of the irradiation beam of the first and/or second wavelength and/or a radiation (photon) density and/or a radiation intensity and/or a radiation power and/or radiation wavelength) for said scanning of the irradiation beam of the first and/or second wavelength across the ophthalmic device, in-process input data such as temperature data of a current and/or predicted temperature of the ophthalmic device during said exposure, refractive index/polarizability data of a refractive index/polarizability of the ophthalmic device to be obtained based on said exposure, the refractive index/polarizability to be obtained in particular relating to a mapping of the refractive index/polarizability to be obtained to a specific location/coordinates of the ophthalmic device, rhexis dimension data of a dimension of a rhexis, and input data such as eye data relating to a dimension and/or a shape of the eye of the patient, positioning data relating to a position and/or orientation of the ophthalmic device relative to the eye, and registration data relating to an identification of the patient and/or the specific eye of the patient.

Preferably, the scan strategy control command data of a scan strategy are a scanning pattern and/or a scanning speed and/or a pulse duration of a pulse and/or radiation intensity as described further below.

The parameters of the irradiation beam(s) may then be adjusted according to the lens data and/or the treatment plan data as defined herein in order to precisely (locally) change the polarizability/refractive index of the ophthalmic device, where desired.

Preferably, the parameters of the irradiation beam(s) are adjusted according to the lens data and/or the treatment plan data as described before or preferably described herein.

The skilled artisan is well aware in this regard that optimum irradiation focus conditions are reached when the depth-of-field (Rayleigh range) of the irradiation beam is matched to the desired thickness of the optical structure to be written into the ophthalmic device.

The skilled artisan is well aware in this regard that optimum irradiation focus conditions are reached when the depth-of-field (Rayleigh range) of the irradiation beam is matched adapted to the local thickness of the ophthalmic device.

In a further embodiment, the lens data comprises data relating to a radiation absorption property (for example an absorption and/or light attenuation coefficient, which may be dependent from the wavelength of light) of a said ophthalmic device, and wherein the system is configured to adjust the first wavelength and/or the second wave-length for said ophthalmic device to locally change the polarizability based on a multi-photon absorption process. For example, based on the material used for the ophthalmic device, a particular wavelength or wavelength ranges may be input for a precise local change of the polarizability of the ophthalmic device.

The one or more irradiation sources as part of the system to be used in the process for adjusting a polarizability of an ophthalmic device according to the invention may comprise one or more pulsed lasers which may be utilized to generate nano-second pulses, preferably pico-second pulses and more preferably femto-second pulses. Preferably, one irradiation source is used. Particular preferably, the one or more irradiation sources comprise one or more pulsed lasers which are used to generate femto-second pulses. Particular preferably, one pulsed laser is used to generate femto-second pulses is used as irradiation for the system according to the invention or for the processes and methods according to the invention.

In one embodiment, the one or more irradiation sources comprise a laser which is tunable to emit a laser beam having the first and second wavelengths, respectively. This may be particularly advantageous as a single laser may be used to (locally) increase or decrease the polarizability/refractive index of the ophthalmic device or intraocular lens, as desired.

Different pulsed laser types are suitable for said irradiation sources within the system to be used in the process for adjusting a polarizability of an ophthalmic device according to the invention. MHz laser as well as kHz laser are suitable and have their particular merits. While a MHz laser system, for example, operates at lower pulse energy, the focused laser spots can be kept at μm-scale (<1 μm to several μm) and thus be used for precise local index modifications in all three dimensions, for example, to generate diffractive structures. A preferred MHz-irradiation source is an 80 MHz laser with a pulse energy ranging from 0.1 to 10 nJ.

A kHz-laser on the other hand operates at higher pulse energy of typically 0.1 to 10 μJ and thus requires a larger spot size of, for example, 10 to 100 μm in order to not damage the lens material. A larger laser spot size, however, implies a large depth of field (=long Rayleigh range) that can be equal to or even exceed the thickness of the ophthalmic device material. For such long Rayleigh ranges, it might not be possible to modify the refractive index layer by layer in the IOL but only uniformly along a line around the focus. A preferred kHz-irradiation source is a laser with a repetition rate of 100 to 500 kHz.

The average power of the irradiation source as described before or preferably described before is preferably between 300 and 600 mW, particular preferably between 400 and 500 mW.

The irradiation source as part of the system to be used in the process for adjusting a polarizability of an ophthalmic device according to the invention preferably comprises a tunable laser that can provide a variable wavelength in the range of approximately 680-1080 nm, such as a Ti:Sapphire laser (for example Chameleon Ultra II by Coherent, Santa Clara, Calif., USA). The system may also comprise an optical parametric oscillator (for example frequency doubled Chameleon Compact OPO-Vis by Coherent, Santa Clara, Calif., USA).

The irradiation source as part of the system to be used in the process for adjusting a polarizability of an ophthalmic device according to the invention particularly preferably comprises a femtosecond pump laser along with an optical parametric amplifier. Said pump laser emits irradiation >10 Watt average power at 1030 nm in <350 fs pulses with a repetition rate of 0.1 to 700 kHz. The radiation of said pump laser is directed to an optical parametric amplifier, where the pump laser output is frequency-doubled and optically mixed, resulting in a final tunable output in a wavelength range of 600 nm to 800 nm. A preferred repetition rate is between 50 and 600 kHz. A particular preferred repetition rate is between 100 and 500 kHz.

The irradiation source as part of the system to be used in the process for adjusting a polarizability of an ophthalmic device according to the invention particularly preferably comprises a femto-second pump laser >10 Watt average power at 1030 nm in combination with an optical parametric amplifier, which is emitting irradiation pulses <350 fs at a repetition rate of 1 to 700 kHz. The radiation of said pump laser is directed to an optical parametric amplifier with one or multiple second-harmonic stages, resulting in a final optical output in a wavelength range of 400 nm to 590 nm. A preferred repetition rate is between 50 and 600 kHz. A particular preferred repetition rate is between 100 and 500 kHz.

The laser types as described before or preferably described before generate a collimated optical beam of a few millimeter in diameter, which is then directed to optics and scanner. The optical beam quality (characterized through the beam quality factor or beam propagation factor) is ideally between 1.0 and 1.5, more ideally between 1.0 and 1.3. According to DIN EN ISO 11146, the optical beam quality is given in the dimension of M².

The first wavelength of the irradiation beam within the system to be used in the process for adjusting a polarizability of an ophthalmic device according to the invention is between 600 nm and 800 nm, preferably between 650 nm and 750 nm, more preferably between 670 nm and 720 nm, more preferably between 680 and 710, in order to (locally) decrease the polarizability (and hence the refractive index) of the IOL.

The second wavelength of the irradiation beam within the system to be used in the process for adjusting a polarizability of an ophthalmic device according to the invention is between 400 nm and 590 nm, preferably between 500 nm and 580 nm, more preferably between 530 nm and 570 nm, in order to (locally) increase the polarizability (and hence the refractive index) of the IOL.

The polarizability may hereby be locally changed particularly precisely.

Optics within the system to be used in the process for adjusting a polarizability of an ophthalmic device according to the invention: The main function of the optics is to focus the irradiation beam, which is emitted from the irradiation source and controlled by the scanner, onto the ophthalmic device. Key considerations as described before are spot size and depth of focus in order to minimize treatment time while staying within limits given by laser safety requirements and material damage as described before as part of common input data. The most important characteristics of the optic is given by its numerical aperture (NA), along with its effective focal length (EFL) and the diameter of the irradiation beam at the entry aperture of the focusing optics. Additionally, all optical elements within the system to be used in the process for adjusting a polarizability of an ophthalmic device according to the invention should be selected for diffraction- or near-diffraction-limited properties, in order to not substantially degrade the optical beam quality.

Different ophthalmic needs will require different spot sizes as the spot size determines the obtainable spatial resolution. Ideally, the spot size is between 1 and 100 μm, more ideally between 50 and 100 μm in order to minimize treatment time while also keeping the potential for material damage low.

Scanner within the system to be used in the process for adjusting a polarizability of an ophthalmic device according to the invention: The scanner to be used within the system to be used in the process for adjusting a polarizability of an ophthalmic device according to the invention may comprise a Galvano-scanner, a piezo scanner, a rotational scanner or an acousto optic modulator or it may be digital such as a spatial light modulator, a digital micromirror device or stereolithography apparatus. Preferably, the scanner as part of the inventive system according to the description is selected from a Galvano-scanner, a piezo scanner, a rotational scanner, an acousto optic modulator, a spatial light modulator, a digital micromirror device or stereolithography apparatus. A preferred Galvano-scanner is a single Pivot-Point-Scanner.

Preferably, the scanner is configured to operate at a scanning speed of more than 50 mm/s. This may allow for keeping the treatment time short. As a general rule, the treatment time should not exceed several minutes and is preferably less than 10 minutes, preferably less than 5 minutes, particularly preferably less than 3 minutes per treatment session.

The treatment area may be defined as the ophthalmic devices volume and size. Typically, the optic of said ophthalmic device or intraocular lens is 5 mm to 7 mm in diameter and typically between 0.2 mm and 2.0 mm thick.

The optimum radiation exposure is <1 kJ/cm² and more ideally <0.3 kJ/cm² to keep the overall irradiation exposure low and treatment time short, while addressing the full volume of the ophthalmic device.

Particularly preferably, random scan patterns or interleaved scanning lines are used to spread out the irradiation energy of the irradiation beam.

The scanning can be performed with three modes. In the bottom-up scanning, the laser may travel from spot-to-spot with a specific dwell time on each spot (“bottom-up, spot-to-spot”). Alternatively, in the bottom-up scanning, the laser may dwell on spots that overlap with one another (“bottom-up, spot overlay”). Alternatively, the laser can travel with a fixed velocity without dwelling on any spots (“fly by, constant velocity”).

In one embodiment of a scan pattern, the IOL is scanned with the irradiation source as described before or preferably described before by shining through the pupil. The IOL, contained in the capsular bag at the time of scanning, is previously inserted through an incision in the cornea using conventional operation procedures. In this embodiment, the full volume of the IOL is scanned and the scanning is performed in a bottom-up manner (i.e. parts of the IOL which are further away from the cornea are scanned first), this way the optical profile is created in order to avoid unnecessary changes in refractive index in the light path.

As described before a key consideration when selecting the scanning program is to minimize local heating of the ophthalmic device and/or the eye of the patient and therefore various variables are used in the scanning program. Taking into account anatomical features such as Rhexis and pupil size as well as optical features such as numerical aperture and laser pulse characteristics, a laser program is created with a specific scanning speed and sequence. The relation between lens coordinate and eye coordinate system are, in this example, automatically taken into account.

The parameters for the scanning program and/or treatment plan are preferably the first and second wavelengths, the scanning speed and sequence, the positioning (e.g. in Cartesian coordinates) of the lens relative to the eye, the scan strategy, the refractive index change which is to be obtained (optical pattern), the numerical aperture of the objective, the Rhexis, the optical diameter (in some examples approximately 6 mm) of the pupil and/or the lens, the pulse duration (shape, intensity and x-y positioning) of the laser beam, laser safety when operating the laser, and centration with respect to the positioning of the lens and the eye.

The photons generated in the laser are in one embodiment of the system to be used in the process for adjusting a polarizability of an ophthalmic device according to the invention preferably guided through mirrors (e.g. as optic 1) to a e.g. a beam expander, which prepares the beam for the subsequent scanner and focusing optic. After passing through the beam expander, the photons are directed toward the scanner (e.g. Galvano-scanner or piezo scanner or rotational scanner or acousto optic modulator or digitally with a spatial light modulator or digital micromirror device or stereolithography apparatus).

After having gone through the scanner, the laser beam travels through another optic such as a divider mirror. In this embodiment, the divider mirror splits up the beam into the main imaging beam for the ophthalmic device irradiation and a beam for monitoring beam properties as well as for positioning feedback. After the divider mirror, the optical beam is focused onto the ophthalmic device by imaging group or focusing optic. In one embodiment, the imaging group comprise a microscope objective to obtain high numerical apertures (for μm-level spatial resolution) or low-NA optics to allow higher pulse energy of μJ-level.

The system as described before or preferably described before may further comprise a microscope objective coupled to the scanner for focusing, by the microscope objective, a said irradiation beam onto said ophthalmic device, wherein the microscope objective has a numerical aperture of between 0.1 and 0.8, preferably between 0.2 and 0.5, and more preferably between 0.2 and 0.4. Providing a microscope objective having such numerical aperture may allow for high irradiation beam quality in particular in terms of focusing and resolution characteristics of the beam used for treating the intraocular lens.

The microscope objective comprises of a typical lens configuration to allow for e.g. correction of chromatic aberration. The microscope objective is preferably linked to an eye interface system, typically a suction system that keeps the eye of the patient in a fixed position as further described below.

In a further embodiment of an objective to be used within the system as described before, the objective is an Olympus LUCPLFLN objective in order to focus the irradiation beam onto the ophthalmic device.

An alternative focusing optic/imaging group is configured with a single aspherical lens with an effective focal length preferably within 50 to 150 mm and a numerical aperture of preferably 0.025 to 0.1.

The system as described before or preferably described before may further comprise a positioning system for determining a position of a said focus of said irradiation beam within a said eye of a said patient, wherein the positioning system is coupled to the scanner and wherein the scanning, by the scanner, of said irradiation beam across said intraocular lens is based on the position of said focus of said irradiation beam within the eye.

The positioning system may comprise a locating system such as an optical coherence tomography system, a confocal microscope or a Scheimpflug camera. The positioning system may be directly or indirectly coupled to the scanner. In some examples in which a confocal microscope is used, the confocal microscope may be directly coupled to the scanner.

The locating system as described before is used to provide topographic data of the eye to the positioning system for determination of the position of the laser focus in dependence of the eye and said intraocular lens.

For confocal microscopy, a partially transparent mirror is used to allow for video imaging.

The system as described before or preferably described before is preferably configured further to determine a location and/or orientation of said intraocular lens relative to the eye and the outlet of the irradiation beam, and wherein the scanning, by the scanner, of said irradiation beam across said intraocular lens is based on the location and/or orientation of said intraocular lens relative to the eye. This may be particularly advantageous since the position of the intraocular lens may not be centered relative to the eye, which misalignment may be taken into account when treating the intraocular lens with the irradiation beam(s).

With respect to the position of the IOL, at least 2 coordinate systems may be considered relevant: coordinates-system of the eye and coordinates-system of the lens within the eye, as both may not be centered with respect to each other.

With respect to the position of the IOL, at least 2 coordinate systems may be considered relevant: x,y,z coordinates of the eye and x,y,z coordinates of the lens within the eye, as both may not be centered with respect to each other.

In one embodiment, the locating system creates input data. These input data contain for example data concerning lens position and/or orientation of the ophthalmic device within the eye and relative to the laser beam outlet, and/or an optical power mapping of the eye and/or the ophthalmic device. These data are used for the calculation of the optical pattern or a continuation of a treatment.

Additionally, it is possible that the locating system creates input data during the writing process. These in-process input data contain for example data concerning lens position and/or orientation of the ophthalmic device within the eye and relative to the laser beam outlet, and/or an optical power mapping of the eye and/or the ophthalmic device. These data are used for in-process modification of the control commands used to generate the optical pattern.

The system as described before or preferably described before may further comprise a temperature management unit coupled to one or both of (i) the one or more irradiation sources and (ii) the scanner, wherein the temperature management unit is configured to determine, based on an irradiation beam property of a said irradiation beam and an ophthalmic device property of a said ophthalmic device, a temperature of a part of said ophthalmic device during said treating of said ophthalmic device by said scanning, and wherein the system is configured to control, based on said determination of the temperature, one or both of (i) the one or more irradiation sources and (ii) the scanner. This may allow for ensuring that the eye and/or the ophthalmic device may not be detrimentally affected based on the treatment with an irradiation beam.

Additionally, the temperature management unit is preferably configured to predict said temperature during said treating of said ophthalmic device, and wherein said input data comprises the predicted temperature. This may allow for taking preventative measures to ensure that the eye and/or the ophthalmic device may not be detrimentally affected based on the treatment with an irradiation beam.

Alternatively, the temperature management unit is an infrared camera logging the temperature of the eye and correlating the measured data with common data bearing calibration data to calculate the real temperature in the eye.

In another embodiment, the temperature dependence of refractive index is used for temperature controlling. In these examples, the system comprises a refractive power mapping device. Based on the deviation of the measured refractive power map and the progress of the writing predicted refractive power map, temperatures in the lens can be calculated in process.

In another embodiment, the temperature dependence of the emission spectrum is used for temperature controlling. In these examples, the system comprises a UV-Vis spectrometer. Based on the deviation of the measured emission peak wavelength and/or peak width, temperatures in the focal spot can be calculated in process.

The system as described before or preferably described before may further comprise an eye interface system configured to keep a said eye of a said patient in a fixed position. The eye interface system may comprise a suction system for fixing the position of the eye of the patient during treatment.

The patient may be “docked” to the system in a lie flat or upright position.

The system as described before or preferably described before may further comprise a wireless or wired receiver and/or transceiver for one or more of (i) sending control commands to the one or more irradiation sources, (ii) sending control commands to the scanner, and (iii) inputting the control command data needed for creating the optical pattern into the scanner.

The one or more irradiation sources and/or the scanner may therefore be controlled remotely. Additionally or alternatively, the data relating to one or both of the lens data and the treatment plan data may be stored externally from the system and may be provided to the system as and when desired.

In some examples, it may be preferable to provide a wired receiver or transceiver at least for controlling the one or more irradiation sources and/or for controlling the scanner in order to reduce (or avoid) any delay when sending a control signal to the one or more irradiation sources and/or the scanner

In another example, the receiver/transceiver sends treatment plan data and lens data to a central computing unit which calculates the optical pattern and sends this as input data back to the receiver which provides it to the system.

The system as described before or preferably described before may further comprise a device for locally measuring the refractive power of said ophthalmic device during said treating of the ophthalmic device. Adjustments to one or more of the irradiation source(s), the scanner and the input data may hereby be made during the treatment process.

The system as described before or preferably described before may further comprise a refractometer for locally measuring the refractive index of said ophthalmic device during said treating of the ophthalmic device. Adjustments to one or more of the irradiation source(s), the scanner and the input data may hereby be made during the treatment process.

Further components of the system providing the photons are optionally a cover in which all the equipment is built in, a power unit to provide the system and all sub-systems with sufficient energy, and sub-systems like a suction system and/or chiller.

In addition to the above mentioned components, controller, firmware and a graphics user interface (GUI) as well as treatment algorithms may be provided. To connect to the system, connectivity may be established via Bluetooth, Wi-Fi or other ports like RS-232.

The invention further relates to a method for locally adjusting a polarizability of an intraocular lens according to the invention arranged within an eye of a patient, wherein the treatment plan data comprises one or more of:

• • scan strategy control command data of a scan strategy (for example a scanning pattern and/or a scanning sequence and/or a scanning speed and/or a scanning duration of the scanning pattern and/or a scanning duration of the scanning sequence and/or a pulse duration of a pulse of the irradiation beam of the first and/or second wavelength and/or an irradiation beam profile of a said irradiation beam and/or a radiation (photon) density and/or a radiation intensity and/or a radiation power and/or radiation wavelength) for said scanning of a said irradiation beam across the intraocular lens,
  • temperature data of a current and/or predicted temperature of the intraocular lens during said exposure,
  • refractive index data of a refractive index of the intraocular lens to be obtained based on said exposure, the refractive index to be obtained in particular relating to a mapping of the refractive index to be obtained to a specific location/coordinates of the intraocular lens,
  • rhexis dimension data of a dimension of a rhexis,
  • eye data relating to a dimension and/or a shape of the eye of the patient,
  • positioning data relating to a position and/or orientation of the intraocular lens relative to the eye, and
  • registration data relating to an identification of the patient and/or the specific eye of the patient.

The invention further relates to a method for locally adjusting a polarizability of an intraocular lens according to the invention arranged within an eye of a patient, wherein said exposing of the intraocular lens to a said irradiation beam comprises exposing a first volume of the intraocular lens prior to exposing a second volume of the intraocular lens, wherein the first volume is further away from the cornea of the eye of the patient than the second volume.

In the above-stated clauses, an initial step of the methods may be to provide a said intraocular lens.

In examples, in which said exposing of the intraocular lens to a said irradiation beam comprises exposing a first volume and/or plane and/or location of the intraocular lens prior to exposing a second volume and/or plane and/or location of the intraocular lens, wherein the first volume and/or plane and/or location is further away from the cornea of the eye of the patient than the second volume and/or plane and/or location, volumes and/or planes and/or locations irradiated at later time points in the irradiation sequence may be closer to the cornea than volumes and/or planes and/or locations irradiated at earlier time points. A said volume may hereby relate to one or more planes of the intraocular lens.

The invention is furthermore related to a method for correcting vision in a patient by modifying the refractive index of an intraocular lens according to the invention within the eye of said patient comprising

• • identifying and measuring the degree of vision correction of the patient;
  • determining the position and type of refractive structures to be written into said intraocular lens to correct the patient's vision; and
  • subsequently exposing said intraocular lens to two-photon or multi-photon irradiation having a wavelength between 600 nm and 800 nm to locally decrease the polarizability of the intraocular lens and/or
  • subsequently exposing said intraocular lens to two-photon or multi-photon irradiation having a wavelength between 400 nm and 590 nm to locally increase the polarizability of the intraocular lens, preferably by using the system and/or the process as described before for exposing said intraocular lens to said irradiation.

As outlined above, the change of polarizability results in a change of refractive index.

Exemplarily, a composition of 12-({2-oxo-3-phenyl-2H-pyrano[3,2-c]pyridin-7-yl}oxy)dodecyl prop-2-enoate (A-097) (0.2 g, 0.42 mmol, 22.5 mol %), n-butyl acrylate (0.17 g, 1.31 mmol, 70.4 mol %) and ethylene glycol dimethacrylate (0.02 g, 0.10 mmol, 5.4 mol %) (EGDMA) as crosslinker is well mixed under stirring using gentle heat and degassed by three freeze pump-thaw cycles. Appropriate amounts (0.02-0.12 equiv.) of a radical initiator (e. g. 1,1′-(3,3,5-trimethylcyclohexylidene)bis[2-(1,1-dimethylethyl)-peroxide [Luperox® 231] or 2-[(E)-2-(1-cyano-1-methylethyl)diazen-1-yl]-2-methylpropanenitrile) are added.

Two glass plates are coated with a polyethylene sheet and a 1 mm thick cell is created between the polyethylene sheets using a silicone rubber gasket. The coated faces of the glass sheets are clipped together using spring clips with a syringe needle being placed between the gasket and the polyethylene sheets. The cavity is then filled with the above formulation or with formulations as indicated further in table 3 through the needle using a gastight syringe. Once the cavity is filled the syringe needle is removed, a final clip is used to seal the mould and the assembly is placed in an oven.

The polymerization temperature is between 60° C. and 180° C. and the individual polymerization conditions are chosen for the respective initiators, which can be extracted for the skilled person from the formulation mixture. The moulds are allowed to cool to room temperature before the polymer plate is removed from the mould.

Refractive index change is induced by irradiation at 340-365 nm. The refractive indices (n) of the blanks at 590 nm are measured on Schmidt+Haensch AR12 before and after irradiation. The following table shows the refractive indice after irradiation as well as the change in refractive index (max. Δn).

The phase transition temperatures are determined with a TA Instruments Q2000 differential scanning calorimeter during heating in the second heating run with 20 K/min from −100° C. to 200° C. in a hermetic aluminium pans.

The results of the application examples 18-5 to 18-8 show a significant refractive index change after irradiation.

Moreover, the addition of the nitrogen within the photoactive chromophore according to the invention has a significant impact on the optical properties over prior art compounds. Homopolymers of representative monomers of the prior art (Ref-[1], Ref-[2], Ref-[3] and Ref-[4]) and the monomers A-001, A-097, A-126 and A-046 are prepared and compared to explain this effect.

Ref-[2] is a monomer as disclosed in WO2017032442 (compound (M-1)).

Ref-[3] is a monomer as disclosed in WO2017032442 (compound (M-42)).

Ref-[4] is a monomer as disclosed in WO2017032442 (compound (M-53)).

This effect and the direct comparison can be seen from the data in Table 5 and is visualized in FIG. 1.

ameans ratio photoactive chromophore (in mmol) per total amount of formulation mixture (in gram).

The ratio photoactive chromophore (in mmol) per total amount of formulation mixture (in gram) is calculated as follows: The compositions according to table 3 consist of various components as described. The weight in grams of all said components in each formulation are summed up. Then the amount of the individual photoactive chromophore in mmol in each formulation (amount of Ref-[1], Ref-[2], Ref-[3], Ref-[4], A-001, A-097, A-126 or A-046) is divided by the prior calculated sum for said formulation comprising said individual photoactive chromophore. The quotient of this mathematic operation is the above mentioned ratio photoactive chromophore (in mmol) per total amount of formulation mixture (in gram).

The advantage as described before of compounds as described in Table 5 is visualized in FIG. 1 where the refractive index change Δn is plotted versus the amount of mmol photoactive chromophore per total amount of the formulation in grams. FIG. 1 shows that the examples according to the invention show a higher refractive index change and partially increased higher refractive starting indices and the total value of refractive index change per mmol photoactive chromophore is much higher compared to the reference materials used.
