ABSTRACT:
An intraocular lens suitable for implantation through a minimal width incision opening into either the anterior chamber or the posterior chamber. The lens incorporates three supporting members, at least one of which is a semi-flexible loop disposed adjacent a next support member to provide wide support while being compressable to an overlapped relationship to provide minimum width for insertion. The lens provides a limited degree of compressability to allow the lens to adapt to differing diameters of implantation location while, at the same time, providing sufficient rigidity so as to prevent undesired bowing.
