Abstract
Abstract A lens suitable for implantation in the eye is provided with laterally extending iris clips each having at least one of its ends locked within the body of the lens. The clips are initially extended through close-fitting openings, terminally beaded and forcefully retracted sufficiently to bury their beaded ends within the lens body. Cold flow of lens material around the beaded ends locks the clips in place.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
91 words
A pseudophakos comprising: a lens of material suitable for implantation in the eye and having a number of openings of a predetermined diametral size extending thereinto; an iris clip formed of a length of wire, at least one end of which is extended into one of said openings, said end of said length of wire terminating with an enlargement of substantially greater cross-sectional size than the diametral size of said opening and being embedded in a surround of the material of said lens, said surround locking said iris clip in place.
Claim 2
Dependent Claim
91 words
A pseudophakos comprising: a lens of material suitable for implantation in the eye and having a number of openings of a predetermined diametral size extending thereinto; an iris clip formed of a length of wire, at least one end of which is extended into one of said openings, said end of said length of wire terminating with an enlargement of substantially greater cross-sectional size than the diametral size of said opening and being embedded in a surround of the material of said lens, said surround locking said iris clip in place.
Claim 3
Dependent Claim
35 words
A pseudophakos according to claim 1 including a plurality of iris clips each formed of a length of wire and having their corresponding opposite ends terminally enlarged and embedded in said material of said lens.
Claim 4
Dependent Claim
29 words
A pseudophakos according to claim 2 wherein said plurality of iris clips include both anterior and posterior configurations respectively spaced apart for reception of an intraocular iris diaphragm therebetween.
Claim 5
Dependent Claim
18 words
A pseudophakos according to claim 2 wherein said iris clips are each in the configuration of a loop.
Claim 6
Dependent Claim
30 words
A pseudophakos according to claim 2 wherein some of said plurality of iris clips are in the form of a loop and others are in the configuration of a strut.
Claim 7
Dependent Claim
41 words
A pseudophakos according to claim 2 wherein one end of each of a pair of said iris clips are placed in juxtaposition within one of said openings in said lens and embedded in said surround of said material of said lens.
Claim 8
Dependent Claim
27 words
A pseudophakos according to claim 6 wherein the terminus of only one of said pair of juxtapositioned ends of said iris clips is provided with an enlargement.
Claim 9
Dependent Claim
57 words
A pseudophakos according to claim 2 wherein said plurality of iris clips includes a pair of loops of wire having their corresponding ends substantially axially aligned, butted and secured together with an enlargement of intregal material, said enlargements being embedded in said surround of the material of said lens for locking said pair of loops in place.
Claim 10
Dependent Claim
40 words
A pseudophakos according to claim 1 including a clasp formed of a length of malleable wire, said clasp having a proximal enlargement disposed within another of said openings and locked thereinplace by a surround of the material of said lens.
Claim 11
Dependent Claim
26 words
A pseudophakos according to claim 9 wherein said clasp is formed of the same type of material as said iris clip but rendered relatively highly malleable.
Claim 12
Dependent Claim
15 words
A pseudophakos according to claim 1 wherein said openings extend only partially through said lens.
Claim 13
Dependent Claim
