Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
124 words
An intraocular lens comprising: a lens body; resilient position-fixation means for positioning said lens body within an eye, said position-fixation means having a first portion integrally connected with and extending from said lens body and having a second portion extending from said first portion, and said position fixation means being deformable between an expanded condition in which said second portion is remote from said lens body and a contracted condition in which said second portion is adjacent to said lens body; and a layer of material which is soluble in the eye, connecting said lens body to said second portion of said position-fixation means in said contracted condition thereof, thereby maintaining said position-fixation means in said contracted condition during insertion thereof into the eye.
Claim 2
Dependent Claim
124 words
An intraocular lens comprising: a lens body; resilient position-fixation means for positioning said lens body within an eye, said position-fixation means having a first portion integrally connected with and extending from said lens body and having a second portion extending from said first portion, and said position fixation means being deformable between an expanded condition in which said second portion is remote from said lens body and a contracted condition in which said second portion is adjacent to said lens body; and a layer of material which is soluble in the eye, connecting said lens body to said second portion of said position-fixation means in said contracted condition thereof, thereby maintaining said position-fixation means in said contracted condition during insertion thereof into the eye.
Claim 3
Dependent Claim
63 words
An intraocular lens in accordance with claim 1 in which said first portion of said position-fixation means is a stem portion, said second portion of said position-fixation means is a limb portion, and said lens includes a pair of said stem portions and a pair of said limb portions and each said limb portion is in substantially overlying relation with said lens body.
Claim 4
Dependent Claim
27 words
An intraocular lens in accordance with claim 2 in which said layer substantially encapsulated both said lens body and said position-fixation means in said contracted condition thereof.
Claim 5
Dependent Claim
24 words
An intraocular lens in accordance with claim 1 in which said material is chosen from the group consisting of human blood, fibrin, and gelatin.
Claim 6
Dependent Claim
54 words
An intraocular lens in accordance with claim 1 in which said material is (a) non-toxic and otherwise compatible with the fluid in the human eye, (b) soluble in the fluid in the eye (c) dryable from a liquid state into a semi-rigid or rigid state and capable of adhereing to and/or encapsulating the lens.
Claim 7
Dependent Claim
32 words
An intraocular lens in accordance with claim 1 in which said material is chosen from the group consisting of chondroitin sulfate, sodium hyaluronate, or a mixture of chondroitin sulfate and sodium hyaluronate.
Claim 8
Independent Claim
166 words
A method of positioning an intraocular lens in an eye, the lens comprising a lens body and resilient position-fixation means for positioning said lens body within an eye, said position-fixation means having a first portion extending from said lens body and having a second portion extending from said first portion, and said position-fixation means being deformable between an expanded condition in which said second portion is remote from said lens body and a contracted condition in which said second portion is adjacent to said lens body, comprising: deforming said position-fixation means into said contracted condition thereof; applying to said lens with deformed position-fixation means a layer of material which is soluble in the eye; connecting said lens body to said adjacent second portion of said position-fixation means with said material to maintain said position-fixation means in said contracted condition thereof; inserting said lens into the posterior chamber of the eye; and allowing said material to dissolve in the eye for seating said lens in the eye.
Claim 9
Independent Claim
166 words
A method of positioning an intraocular lens in an eye, the lens comprising a lens body and resilient position-fixation means for positioning said lens body within an eye, said position-fixation means having a first portion extending from said lens body and having a second portion extending from said first portion, and said position-fixation means being deformable between an expanded condition in which said second portion is remote from said lens body and a contracted condition in which said second portion is adjacent to said lens body, comprising: deforming said position-fixation means into said contracted condition thereof; applying to said lens with deformed position-fixation means a layer of material which is soluble in the eye; connecting said lens body to said adjacent second portion of said position-fixation means with said material to maintain said position-fixation means in said contracted condition thereof; inserting said lens into the posterior chamber of the eye; and allowing said material to dissolve in the eye for seating said lens in the eye.
Claim 10
Dependent Claim
57 words
A method in accordance with claim 7 in which the step of applying to said lens a layer of material comprises applying to said lens a layer of wet material and which includes the step of drying said material while holding said position-fixation means in said contracted condition thereof just prior to insertion thereof into the eye.
Claim 11
Dependent Claim
49 words
A method in accordance with claim 7 in which the step of applying to said lens a layer of material comprises applying to said lens a layer of wet material and which includes the step of permitting said material to harden just prior to insertion thereof into the eye.
Claim 12
Dependent Claim
42 words
A method in accordance with claim 7 in which the step of applying said layer of material comprises placing said lens into a mold adapted to hold the postion-fixation means in said contracted condition thereof and pouring said material into said mold.
Claim 13
Dependent Claim
31 words
A method in accordance with claim 7 wherein said step of applying said layer of material comprises encapsulating substantially all of said lens body and said position-fixation means with said material.
