ABSTRACT:
A posterior chamber lens implant has a lens and a pair of haptics or holding loops. Each loop has an elongated flange projecting from the lens and extending approximately one-quarter of the way around the lens periphery. A free loop portion projects from the flange and curves around the lens so as to overlap the flange of the other loop. Accordingly, the flanges are positioned, relative to the loops, so as to be substantially axially oriented during implantation and so that one flange acts as an insertion guide for the lens body. When implanted, the loops encircle the lens so as to center the lens and protect the lens against secondary fiber growth.
