ABSTRACT An intraocular lens device is provided with fixation elements for centering it in the eye. At least one of the fixation elements comprises an elon- gated resilient strut carried at one end by the lens and having a first portion extending outwardly of the lens generally toward circumferential eye structure, the second portion having a contacting surface engage- able with the eye structure, and a third portion ex- tending from the contact surface generally inwardly toward the lens for a distance, measured radially in- wardly toward the lens axis, of at least about two- fifths of the radial distance of the contact surface from the lens axis. The third portion has a free end, providing the at least one fixation element with sub- stantial elastic flexibility. The generally inwardly- extending third portion of the strut prevents the end of the strut from becoming captured by a peripheral iridectomy opening.
