ABSTRACT:
An intraocular lens for use as an artificial lens implant anteriorly of the iris which has at least a pair of position fixation elements providing a multi-point support for the lens. The position fixation elements are constructed and arranged for sufficient flexibility to permit a single lens to have the capability of being used as an implant in eyes with anterior chamber diameters of a substantial variety in sizes, thereby minimizing the inventory of lenses necessary to be maintained in operating rooms.
