ABSTRACT:
A method for making a composite intraocular lens having an optic portion and haptic portion. The method includes the steps of forming a core of a high refractive material suitable for use as an intraocular lens optic, swelling the core, placing a polymerizable material capable of forming an intraocular lens haptic about the core, and polymerizing the polymerizable material. The method further includes the step of machining the resulting composite rod in order to form a composite intraocular lens having an optic portion and a haptic portion.
