Abstract
An intraocular lens for replacing the natural human eye lens during cataract surgery. The lens provides fixation struts for centering the lens within the eye, and is characterized by including posteriorly extending protrusions on portions of the struts. The protrusions define generally a plane spaced posteriorly of the lens body, and thereby hold the intact posterior lens capsule away from the lens body, facilitating the performance of a posterior capsulotomy using a laser beam. The protrusion desirably is carried on the portion of the strut adjacent the lens body, and preferably extends about the circumference of the lens at least about 45 degrees of the periphery of the lens at a distance closer to the lens periphery than about one-half of the radial distance from the lens periphery to the tissue-engaging surface of the strut.
