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.

A method for making a composite intraocular lens having a optic portion and a haptic portion, said method comprising the steps of:
- forming a core of a high refractive material suitable for use as an intraocular lens optic;
- swelling said core;
- polymerizing about said core a polymerizable material capable of forming said haptic portion to form an outer layer about said core, whereby said outer layer is bonded to said core, said outer layer and said core forming a composite rod;
- and
- machining said composite rod to form said composite intraocular lens having an optic portion and a haptic portion.
A method for making a composite intraocular lens having an optic portion and a haptic portion, said method comprising the steps of:
- forming a core of a high refractive material suitable for use as an intraocular lens optic, said high refractive material comprising a copolymer of hydroxyethyl methacrylate and a comonomer of hydroxyethyl methacrylate;
- positioning said core in a mold;
- placing a polymerizable material capable of forming said haptic portion of said composite intraocular lens in said mold about said core;
- polymerizing said polymerizable material capable of forming said haptic portion to form an outer layer about said core, whereby said outer layer is bonded to said core, said outer layer and said core forming a one-piece rod;
- and
- machining said one-piece rod to form said composite intraocular lens having an optic portion and a haptic portion.
