Photocurable siloxane polymers

A polysiloxane copolymer having functional acryl groups capable of being photopolymerised into a solid intraocular lens, having a specific gravity greater than about 1.0, a refractive index suitable for restoring the refractive power of the natural crystalline lens, wherein the polysiloxane copolyme...

Beschreibung
Zusammenfassung:	A polysiloxane copolymer having functional acryl groups capable of being photopolymerised into a solid intraocular lens, having a specific gravity greater than about 1.0, a refractive index suitable for restoring the refractive power of the natural crystalline lens, wherein the polysiloxane copolymer has siloxane monomer units selected among substituted or unsubstituted arylsiloxanes, arylalkylsiloxanes and alkyl(alkyl)siloxane and at least one of the siloxane monomer units is an aryl siloxane or arylalkylsiloxane, and at least one of the siloxane monomer units is substituted with one or more fluorine atoms.
