First Claim
Patent Images
1. An intraocular lens suitable for use as an artificial lens implant anteriorly of the iris, the lens comprising:
- a medial, light-focusing lens body; and
at least a pair of lateral position fixation elements connected with said lens body;
at least one of said pair of position fixation elements having a first portion contiguous to and extending generally laterally outwardly from a first region of the periphery of said lens body, andthe other of said pair of position fixation elements having a first portion contiguous to and extending generally laterally outwardly from a second region of the periphery of said lens body spaced from and generally opposite said first region and in a direction generally opposite to that of said first portion of said one position fixation element;
said other of said pair of position fixation elements having a second portion pivotable about the end of said first portion of said other of said pair of position fixation elements before being attached to said first portion of said other of said pair of position fixation elements at a selected position before implantation in the eye.

Abstract
An intraocular lens for use as an artificial lens implant anteriorly of the iris which has a pair of position fixation elements providing a three-point support for the lens. One of the position fixation elements has a portion swivelable about a base portion attached to the lens body so that the position fixation element may be adjusted to provide a three-point support corresponding to measured dimensions of the eye and may be attached in the selected position by sutures before implantation in the eye.

14. The method of making an intraocular lens having a lens body and at least a pair of position fixation elements connected with said lens body, a second portion of a position fixation element being pivotable about the end of a first portion thereof, comprising:
-
measuring predetermined dimensions of the eye; pivoting said second portion about said first portion of a position fixation element to correspond with the measured dimensions of the eye; and attaching said second portion to said first portion of the position fixation element in the selected position.
