Abstract
Abstract An intraocular lens utilizing an optical lens portion adapted to position over the pupil along the optical axis. A first member and an adjustable second member, space apart under the cornea extend away from the lens portion to the periphery of the iris. The adjustment of the second member permits wedging of the intraocular lens beneath the optical portion of the cornea.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
107 words
An intraocular lens for an eye comprising: a. lens portion adapted for positioning over the pupil; b. first member adapted for extending away from said lens portion to the periphery of the iris and being fixed to said lens portion; c. second adjustable member adapted for extending a selected distance away from said lens portion to the periphery of the iris and spaced along the periphery of the iris from said first member, said second adjustable member including a first projection connected to said lens portion; a second projection being adjacent said first projection; and means for positioning said first projection in relation to said second projection.
Claim 2
Dependent Claim
107 words
An intraocular lens for an eye comprising: a. lens portion adapted for positioning over the pupil; b. first member adapted for extending away from said lens portion to the periphery of the iris and being fixed to said lens portion; c. second adjustable member adapted for extending a selected distance away from said lens portion to the periphery of the iris and spaced along the periphery of the iris from said first member, said second adjustable member including a first projection connected to said lens portion; a second projection being adjacent said first projection; and means for positioning said first projection in relation to said second projection.
Claim 3
Dependent Claim
31 words
The intraocular lens of claim 1 in which said first member includes two spaced edge portions, each adapted for extending away from said lens portion to the periphery of the iris.
Claim 4
Dependent Claim
33 words
The intraocular lens of claim 2 in which said second adjustable member includes two spaced edge portions, each adapted for selectively extending away from said lens portion to the periphery of the iris.
Claim 5
Dependent Claim
24 words
The intraocular lens of claim 1 in which said positioning means includes clamping means for releasably holding said first projection against said second projection.
Claim 6
Dependent Claim
47 words
The intraocular lens of claim 4 in which said positioning means includes serrations on said first and second projections, said serrations mating with each other at a plurality of positions between said adjacent first and second projections, said clamping means releasably mating said first and second projections.
Claim 7
Dependent Claim
40 words
The intraocular lens of claim 5 in which said first and second projections each include an ear able to receive a force for positioning said first and said projections in any of said plurality of positions where said serrations mate.
Claim 8
Dependent Claim
25 words
The intraocular lens of claim 6 in which said adjustable member additionally comprises means for continually forcing said second projection away from said first projection.
Claim 9
Dependent Claim
31 words
The intraocular lens of claim 7 in which said first member includes two spaced edge portions, each adapted for extending away from said lens portion to the periphery of the iris.
Claim 10
Dependent Claim
