In a method of producing an intraocular lens having a substantially clear optic and at least one filamentous haptic having high fracture toughness, solid particles are mixed into an uncured polymer, and the mixture is inserted into a mold. Ultrasonic energy is applied to the mold until the mixture solidifies. Heat is applied to complete the curing process. Ultrasonic energy is also preferably applied to the particles and uncured polymer mixture to improve dispersion of the particles therein.

Method of producing haptics for intraocular lenses having high fracture

An intraocular lens comprises a substantially clear optic and at least one filamentous haptic having high fracture toughness. The haptic is formed of a polymer composition comprising low concentrations of solid particles uniformly dispersed throughout a polymer matrix.
