Abstract
A one-piece intraocular lens made entirely of three-dimensionally crosslinked polymethyl methacrylate is described. The lens is made from a lens blank which is selectively press-stretched in those areas around the periphery of the central effective optic area and from which the haptic portions are formed rendering areas more robust and less prone to fracture while the central effective optic area is not press-stretched. The lenses are durable to YAG laser irradiation.
