Abstract

An intraocular lens utilizing an optical lens portion adapted to position over the pupil along the optical axis. The lens includes a first member extending away from the lens portion to the periphery of the iris of the eye and being fixed to the lens portion. A second adjustable member includes a projecting element and a wedging piece which are forced toward one another, causing fixation of the lens portion.

Claims

1. 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 fixed to said lens;

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 projecting element extending away from said lens portion and being fixed to said lens portion, a wedging piece having an edge portion adapted for extending to the periphery of the iris, and means for urging said wedging piece toward said projecting element.

2. The intraocular lens as claimed in claim 1 characterized in that said urging means includes at least one elastic band surrounding a portion of said projecting element and a portion of said wedging piece.

3. The intraocular lens as claimed in claim 2 characterized in that said projecting element includes a first leg having a second leg angularly connected thereto, and a supporting member, said wedging piece adapted for sliding contact with said second leg of said projecting element and said supporting member.

4. The intraocular lens as claimed in claim 3 characterized in that said second leg and said supporting member are in spaced relationship forming a gap therebetween.

5. The intraocular lens as claimed in claim 4 characterized in that said urging means includes two elastic bands spaced from one another and said second leg includes at least two recesses for encompassing a portion of each of said pair of elastic bands.

6. The intraocular lens as claimed in claim 5 characterized in that said second leg of said projecting element includes at least two recesses for encompassing a portion of each of said pair of elastic bands.
