ABSTRACT:
Disclosed is an intraocular lens comprising a lens element and a plurality of haptics extending therefrom, at least one of the haptics having an anchoring filament with an enlarged complete or partial mushroom-shaped end fixedly disposed inside a passage in the lens element. Also disclosed is a method for fixing a haptic having an anchoring filament to a lens element in a soft intraocular lens comprising the steps of (a) forming in the lens element a passage having a width that is less than the greatest width of the anchoring filament, (b) lubricating the anchoring filament of the haptic, the passage in the lens element, or both, (c) inserting the anchoring filament end-first into the passage, and (d) washing the intraocular lens to remove the lubricant.
