Abstract
An intraocular lens four point contact haptics with an asymmetrical cross section. The ends of each of the haptics are contiguously juxtaposed and inserted in a common bore in the periphery of the optic. The legs of each of the haptics spiral outwardly in juxtaposed relationship, separate and extend away from each other to form eye contacting heel and toe portions residing on opposing sides of the inferior-superior axis of the lens. When two such haptics are employed, a wide haptic compression range can be achieved with little differential in compression force.
