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 elongated 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 engageable with the eye structure, and a third portion extending from the contact surface generally inwardly toward the lens for a distance, measured radially inwardly 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 substantial 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.
