This invention describes a case for storing an ophthalmic lens and, more specifically, in some embodiments, programmable and communication elements of a base capable of receiving and disinfecting a case storing an ophthalmic lens such as a contact lens.
It is well known that contact lenses can be used to improve vision. Various contact lenses have been commercially produced for many years. Early designs of contact lenses were fashioned from hard materials. Although these lenses are still currently used in some applications, they are not suitable for all patients due to their poor comfort and relatively low permeability to oxygen. Later developments in the field gave rise to soft contact lenses, based upon hydrogels.
Hydrogel contact lenses are very popular today. These lenses are often more comfortable to wear than contact lenses made of hard materials. Many hydrogel contact lenses may be worn for more than one day. However, a build-up of microbial life and bacteria on the lenses generally makes it desirable to periodically remove the lenses and disinfect them.
Disinfection of contact lenses traditionally entails placing the contact lens in a container or case and subjecting the contact lens to a chemical disinfectant. However, chemical disinfectants are not always as efficacious as may be desired. From time to time, a contact lens with a bacterium, mold, fungus or other type of adverse life form is reinserted into a user's eye with the result being a diseased eye. In addition, disinfecting solutions tend to be expensive and add to the total cost of using contact lenses for vision correction or cosmetic enhancement. New methods and approaches are therefore needed to disinfect contact lenses.
Accordingly, the present invention includes an ophthalmic lens disinfecting base unit consisting of a lens storage case and the radiation disinfecting base unit. The lens storage case is capable of storing reusable contact lenses and disinfecting the lenses during the storage by receiving disinfecting radiation in a wavelength and intensity suitable to kill unwanted bacteria, viruses, molds, fungi and the like on a contact lens. The radiation disinfecting base unit receives a lens storage case and provides controlled disinfecting radiation in a wavelength and intensity suitable to kill the unwanted bacteria, viruses, molds, fungi and the like on a contact lens and, in some embodiments, on a lens storage case.
In some embodiments, an ophthalmic lens disinfecting unit includes logic to record and analyze data, to control functions of the ophthalmic lens disinfecting unit, and to display relevant user messages. In other embodiments of the present invention, various programming options are available for an ophthalmic lens disinfecting unit. The present invention may, additionally, include communication options.
The present invention includes methods and apparatus for storing and analyzing data related to disinfecting an ophthalmic lens, for controlling functions of an ophthalmic lens storage unit, and for displaying relevant user messages. Also included are options for programming an ophthalmic lens storage unit. Further, communication options allow data to be communicated between an ophthalmic lens storage unit and external devices or entities for various purposes.
In the following sections detailed descriptions of embodiments of the invention will be given. The descriptions of both preferred and alternative embodiments are exemplary embodiments only, and it is understood by those skilled in the art that variations, modifications, and alterations may be apparent. It is therefore to be understood that said exemplary embodiments do not limit the scope of the underlying invention.
