Anterior chamber implant lens

Claim 1

An intraocular implant unit for installation and immobilization in a circularly bounded chamber of an eye of a patient comprising: a lens disposed in a first plane for insertion within the chamber of the eye; a limb integral with and extending outward from a margin portion of said lens to a second plane for placement within the chamber of the eye, said second plane being spaced apart from said first plane; means extending from said limb and lying in said second plane for engaging a first portion of the chamber to thereby minimize torsional movement of said lens in the chamber; a flexible strand having a first end connected to said lens in said first plane and a second end lying in said second plane; and an elongated arcuate portion extending from said flexible strand second end and lying in said second plane for engaging a second portion of the chamber approximately opposite said first portion of the chamber, said elongated arcuate portion being disposed approximately opposite said means extending from said limb, and said flexible strand being doubly folded in a third plane approximately common to said first end of said flexible strand and to the ends of said elongated portion to flex in said third plane between said flexible strand first end and said elongated arcuate portion for varying the distance between said lens and said elongated arcuate portion, such that said elongated arcuate portion may engage said second portion of the chamber, said doubly folded portion not being engageable with eye tissue defining the chamber to thereby adjust the intraocular implant unit to the size of the chamber at a position between said second portion of the chamber and said lens and immobilize the implant unit in the chamber.
