  • Patent number: 4995879
    Abstract: An improved intraocular lens and related method of production are provided, wherein resilient drawn haptics are formed integrally with a lens body for supporting the lens body at a centered position with a patient's eye. A lens preform is constructed from a selected polymeric material to include the lens body having integrally formed lobes at selected points on the periphery thereof. The lobes are then drawn outwardly under elevated temperature conditions and set with a selected curvature to form resilient, substantially filamentary haptics or support loops of a desired shape. Such drawing of the polymeric material results in substantial alignment of polymers longitudianlly along the haptics such that the haptics exhibit a combination of significant resiliency and high structural strength.
