Zusammenfassung:	An intraocular lens includes an optic body and a pair of cantilevered spiral support members or haptics extending outwardly from a peripheral portion of the optic body. The haptics are formed as portions of an elongate cylindrical body. A method of making the haptics is disclosed which allows the haptic to be of variable cross sectional area, to be aplanar, and to include bends and curves, for example, without introducing undesirable molecular level changes or damage into the material of the haptic, which molecular level changes result in conventional haptics undesirably having a memory of their former shape and resulting dimensional changes (creep) of the conventional haptics over time.
