Abstract:
An injectable lens material having suitable viscosity for being injected through standard cannula and comprising a mixture of a polysiloxane copolymer, a photoinitiator, and, optionally, a crosslinking agent, wherein the polysiloxane copolymer is capable of being photopolymerized into a solid intraocular lens and has functional acryl groups at terminal ends of the copolymer, a specific gravity greater than about 1.0, a refractive index suitable for restoring the refractive power of the natural crystalline lens, and siloxane monomer units in the polysiloxane copolymer selected from the group consisting of substituted and unsubstituted arylsiloxanes, substituted and unsubstituted arylalkylsiloxanes, and substituted and unsubstituted alkyl(alkyl)siloxanes, and mixtures thereof, wherein at least one of the siloxane monomer units is substituted with one or more fluorine atoms, and wherein at least one siloxane monomer unit is an arylsiloxane or an arylalkylsiloxane.
