Abstract:
A method of forming an intraocular lens, comprising the steps of:providing an optical mold cavity within a mold; positioning a pair of core pins above said mold cavity; introducing material for forming said intraocular lens into said mold cavity; curing said lens material to form an optical element, wherein said lens material cures around said core pins and does not significantly adhere thereto; removing said core pins to form haptic-mounting holes wherein said holes are tangential to an edge of said optical element and an inner surface of said holes is coated with a thin layer of fumed silicone dioxide after tumbling; tumble polishing said optical element in a tumbler, to radius or polish said edge of said optical element and to abrade away any flash present on said optical element; and adhesively bonding a haptic within each of said holes.
