Abstract
A method for making a biodegradable ophthalmic lens includes steps of mixing poly[bis(methacrylate)phosphazene], hydrophilic monomers, and a photoinitiator to form a mixture; feeding the mixture into a mold, and heating or exposing the mixture to ultraviolet radiation, thereby causing the poly[bis(methacrylate)phosphazene] to function as a cross-linking agent. Such cross-linking agent undergoes a polymerization reaction with the hydrophilic monomers and the photoinitiator to form a polyphosphazenes hydrogel; and the polyphosphazenes hydrogel is then removed from the mold.
