Dry eye disease is a common condition that occurs when an individual's tears are not able to provide adequate lubrication for their eyes. Tears can be inadequate and unstable for many reasons. For example, dry eyes may occur if the individual does not produce enough tears or if they produce poor-quality tears. This tear instability leads to inflammation and damage of the eye's surface. Also, many individuals may suffer from Blepharitis which is an inflammatory condition of the eye lids and Meibomitis which is an inflammatory condition of the glands in the eyelid. When the glands become inflamed this could cause poor secretion or no secretion of oil that coats the surface of the eye. This lack of oil will cause evaporation of the water component of individual's tears, thus leading to dry eyes.
Maintaining proper ocular surface hygiene is a challenge.
The following detailed description illustrates embodiments of the present disclosure. These embodiments are described in sufficient detail to enable a person of ordinary skill in the art to practice these embodiments without undue experimentation. It should be understood, however, that the embodiments and examples described herein are given by way of illustration only, and not by way of limitation. Various substitutions, modifications, additions, and rearrangements may be made that remain potential applications of the disclosed techniques. Therefore, the description that follows is not to be taken as limiting on the scope of the appended claims. In particular, an element associated with a particular embodiment should not be limited to association with that particular embodiment but should be assumed to be capable of association with any embodiment discussed herein.
Dry eye disease is a common condition that occurs when an individual's tears are not able to provide adequate lubrication for their eyes. Tears can be inadequate and unstable for many reasons. For example, dry eyes may occur if the individual does not produce enough tears or if they produce poor-quality tears. This tear instability leads to inflammation and damage of the eye's surface. In addition, many individuals may suffer from Blepharitis which is an inflammatory condition of the eye lids and glands. In addition, when the glands become infected this could cause the glands from secreting oil that coats the surface of the eye. This lack of oil will cause the water component of an individual's tears from evaporating, and thus drying out. This is known Meibomian gland dysfunction. The oil that does make it out of the glands can be granular (i.e., crusty) or otherwise unhealthy and can cause irritation.
Meibomian gland dysfunction is very common. In the early stages, individuals are often asymptomatic. However, if left untreated this dysfunction can cause or exacerbate dry eye symptoms and eyelid inflammation. Chronically clogged glands eventually become unable to secrete oil which results in permanent changes in the tear film and dry eyes.
The intent of the embodiments described herein is for ocular surface hygiene, that when used correctly, will substantially reduce the prevalence of dry eye disease and ocular surface disease, which are commonly caused by Meibomian gland dysfunction or Blepharitis. Ocular surface is defined herein as an individual's (i.e., a human) eye lids, eye lashes, and all associated glands that when not healthy and clean contribute to ocular surface disease and dry eye symptoms. Further, the apparatus has features that provide ocular debridement by effectively removing harmful foreign matter that may be present on the ocular surface.
Further, the apparatus described herein may be made of silicone or other similar material, such as plastic polymers or synthetic rubber for example. The cleaning apparatus may be flexible, waterproof, durable, cleanable, and gentle on the ocular surface.
In or more embodiments, the sole bottom 106 includes an array of bristles 110 coupled to the sole bottom 106. Note, only one bristle 110 is labeled in the figures for clarity. The small bristles 110 serves as the brush-like surface for the hygiene and debridement of the eyelids, eyelashes, and associated structures. In addition, the array of bristles 110 may vary in size and number and may be positioned in staggered rows and columns.
As further illustrated in
The bristle 110 may include a bristle top 118 that forms a conical shape. The tapered and conical shape of the bristle 110 and bristle top 118 is designed to effectively remove, lift, or dislodge stubborn lid debris from an individual's ocular surface.
As further illustrated in
In one or more embodiments, the finger sole 102, the bristles 110, the finger strap 108, and the elongated handle 122 are flexible. In one or more embodiments, the finger sole 102, the bristles 110, the finger strap 108, and the elongated handle 122 are manufactured from a polymer or other similar material. In addition, the finger sole 102, the bristles 110, the finger strap 108, and the elongated handle 122 may have a rubber material hardness of between 30A Shore and 50A Shore.
The ocular adnexa cleaning apparatus may have different design variations. For example, the apparatus may form a dome structure with multiple clusters of bristles.
As illustrated in
In one or more embodiments, the finger glove 202 includes an outer surface 206. The outer surface 206 may include a first pad 208 integrally coupled to the outer surface 206. In one or more embodiments, the first pad 208 may include a first array of bristles 210 integrally coupled to the first pad 208. Note, only one bristle 210 is labeled in the figures for clarity.
As illustrated in
In one or more embodiments, the first array of bristles 210 is integrally coupled to the first pad 208 at an angle of substantially thirty degrees (i.e., within one, three, or five degrees). In one or more embodiments, the second array of bristles 214 is integrally coupled to the second pad 212 at an angle of substantially thirty degrees (i.e., within one, three, or five degrees).
As illustrated in
Both embodiments (i.e., ocular adnexa cleaning apparatus 100 and enclosed ocular adnexa cleaning apparatus 200) are used similarly.
In operation, as illustrated in
In one aspect, the ocular adnexa cleaning device includes a finger sole having a sole surface and a sole bottom. The ocular adnexa cleaning device includes an array of bristles coupled to the sole bottom and a finger strap coupled to the sole surface.
Implementations may include one or more of the following. An elongated handle may be coupled to the finger sole. The finger sole, the bristle, the finger strap, and the elongated handle may be flexible. The finger sole, the bristles, the finger strap, and the elongated handle may be manufactured from a polymer. The bristles may include a bristle base having a bristle base diameter (BBD), a bristle end having a bristle end diameter (BED), wherein the bristle base diameter (BBD) may be larger than the bristle end (BED). The bristle end may form a conical shape. The bristle end may have a length of 2.54 millimeters. The bristles may have a rubber material hardness of between 30A Shore and 50A Shore. The bristles may be positioned in staggered rows and columns. The bristles may have a separation distance of 0.51 millimeters.
