An intraocular lens suitable for use as an artificial lens implant including a medial light focusing lens body, a stem protruding from the periphery of the lens body to an outer edge thereof formed as a stem footplate adapted to make contact with eye tissue, and first and second flexible members extending from opposite sides of the stem footplate. The end of each of the flexible members is formed as a flexible member footplate so that the three footplates make contact with eye tissue at equally angularly spaced positions from the center of the lens body.
