Claim 1
Independent Claim
243 words
An improved ocular prosthesis comprising: a body portion having an anterior surface, a spatially disposed posterior surface, and a channel formed therebetween; iris forming means disposed on the anterior surface of the body portion, the iris forming means having a transparent central portion, an outer iris colored portion, and a pupil colored area selectively positioned in the transparent central portion, the transparent central portion substantially corresponding in size to a pupil of a natural eye when same is exposed to indirect light, the pupil colored area substantially corresponding in size to the pupil of the natural eye when same is exposed to direct light; pupil colored surface forming means disposed within the body portion between the posterior surface of the body portion and the channel such that the pupil colored surface forming means is substantially adjacent the channel and at least a portion of the pupil colored surface forming area is aligned with the transparent central portion of the iris forming means; and an iris colored member positioned within the channel of the body portion and selectively movable between a first position and a second position, in the first position the iris colored member being in a non-interposing relationship between the transparent central portion of the iris forming means and the pupil colored surface forming means, in the second position the iris colored member being interposed between the transparent central portion of the iris forming means and the pupil colored surface forming means.
Claim 2
Dependent Claim
243 words
An improved ocular prosthesis comprising: a body portion having an anterior surface, a spatially disposed posterior surface, and a channel formed therebetween; iris forming means disposed on the anterior surface of the body portion, the iris forming means having a transparent central portion, an outer iris colored portion, and a pupil colored area selectively positioned in the transparent central portion, the transparent central portion substantially corresponding in size to a pupil of a natural eye when same is exposed to indirect light, the pupil colored area substantially corresponding in size to the pupil of the natural eye when same is exposed to direct light; pupil colored surface forming means disposed within the body portion between the posterior surface of the body portion and the channel such that the pupil colored surface forming means is substantially adjacent the channel and at least a portion of the pupil colored surface forming area is aligned with the transparent central portion of the iris forming means; and an iris colored member positioned within the channel of the body portion and selectively movable between a first position and a second position, in the first position the iris colored member being in a non-interposing relationship between the transparent central portion of the iris forming means and the pupil colored surface forming means, in the second position the iris colored member being interposed between the transparent central portion of the iris forming means and the pupil colored surface forming means.
Claim 3
Dependent Claim
25 words
The improved ocular prosthesis of claim 1 wherein the body portion has a configuration substantially corresponding to the orbital soft tissue of an eye socket.
Claim 4
Dependent Claim
40 words
The improved ocular prosthesis of claim 2 wherein the iris forming means and the anterior surface of the body portion surrounding the iris forming means are provided with a convex surface substantially corresponding to the surface of a natural eye.
Claim 5
Dependent Claim
53 words
The improved ocular prosthesis of claim 1 wherein the iris forming means comprises a corneal button having an anterior side and a spatially disposed posterior side, the anterior surface being covered with an effective amount of a transparent polymeric material to provide the desired convex surface and provide a desired visual depth thereto.
Claim 6
Dependent Claim
30 words
The improved ocular prosthesis of claim 4 wherein the pupil colored area is a substantially circularly shaped black area, and the pupil colored surface forming means is a black disc.
Claim 7
Dependent Claim
40 words
The ocular prosthesis of claim 5 wherein the black disc forms one side portion of the channel and at least a portion of the posterior side of the corneal button forms a spatially disposed second side portion of the channel.
Claim 8
Dependent Claim
49 words
The ocular prosthesis of claim 1 wherein the iris colored member is a disc having a first side and a second side, at least the first side of the disc being colored to substantially correspond to the color of the outer iris colored portion of the iris forming means.
Claim 9
Dependent Claim
60 words
The ocular prosthesis of claim 1 which further comprises a transparent, free-flowing fluid disposed within the channel for stabilizing the iris colored member in one of the first and second positions and for substantially friction-free movement of the iris colored member as the iris colored member is selectively moved through the channel between one of the first and second positions.
Claim 10
Dependent Claim
17 words
The ocular prosthesis of claim 8 wherein the transparent, free-flowing fluid is a low molecular weight silicone.
Claim 11
Dependent Claim
71 words
The ocular prosthesis of claim 1 wherein the iris colored member comprises: a disc having a first side and an second side, the first side of the disc being disposed in a facing relationship with the anterior surface of the body portion; and ferro-magnetic means for imparting magnetic properties to the disc such that the disc can be selectively moved between one of the first and second position via a magnet.
Claim 12
Dependent Claim
23 words
The ocular prosthesis of claim 10 wherein the ferro-magnetic means comprises a ferro-magnetic element secured to the opposed second side of the disc.
Claim 13
Dependent Claim
36 words
The ocular prosthesis of claim 11 wherein the ferro-magnetic element comprises an orthodonic wire ring secured to the second side of the disc such that the wire ring is substantially adjacent the perimeter of the disc.
