Estimating the term…
A process for forming an intraocular lens with haptics having high fracture toughness mixing solid particles with an uncured polymer matrix and introducing the uncured mixture into a mold. Ultrasonic energy is then applied to the mold until the uncured mixture begins to solidify. Sufficient heat is then applied to the polymer mixture to completely cure the polymer. The cured polymer which will form the haptics, is then removed from the mold and a hole for forming the optic is formed in the cured polymer. An uncured polymer matrix suitable for use, when cured, as an optic, is then introduced into the hole and cured. An intraocular lens is then machined from the resulting cured composition.
