Patent

CA 2465500

Relatively high refractive index polymeric compositions and ophthalmic devices such as for example intraocular lenses and corneal inlays made therefrom are described herein. The preferred polymeric compositions are produced through the copolymerization of one or more aromatic-substituted polysiloxane prepolymers with one or more aromatic monomers, alkylated monomers or hydrophilic monomers.

L'invention concerne des compositions polymères à indice de réfraction relativement élevé et des dispositifs ophtalmologiques, tels que des lentilles intraoculaires et des incrustations cornéennes, fabriqués à partir de ces compositions. Les compositions polymères préférées sont produites par copolymérisation d'au moins un prépolymère polysiloxane à base de substituant aromatique avec au moins un monomère aromatique, un monomère alkylé ou un monomère hydrophile.
