Intraocular lens

An intraocular lens device comprising a lens for placement adjacent a side of the iris of an eye with the lens axis substantially aligned with the pupillary axis;

• and
• fixation elements carried by the lens for supportive engagement with eye structure circumferential of the pupillary axis, at least one fixation element comprising an elongated resilient strut carried at one end by the lens, the strut having a first portion extending outwardly of the lens generally toward said circumferential eye structure, said first portion including a proximal portion carried by the lens and spiraling outwardly of the lens periphery in one direction, and a distal portion curved in the opposite direction outwardly of the lens periphery, the latter merging into the proximal portion;
• a second portion having a contact surface engageable with the circumferential eye structure;
• and a third portion extending from the contact surface inwardly toward the lens for a distance, measured radially from the contact surface inwardly toward the lens axis and when the strut is at rest, of at least 0.40 of the radial distance of the contact surface from the lens axis, said third portion having a free end.

• the radius of curvature taken along the length of the strut of all outer, tissue confronting outwardly facing surfaces of the strut extending outwardly of the lens axis more than about three-fifths of the radial distance from the lens axis to the contact surface being at least about 0.8 mm.
