Patent

CA 2465495

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 ophtalmiques, notamment par exemple des lentilles intraoculaires et des implants cornéens fabriqués à partir de ces compositions. Les compositions polymères préférées sont produites par la copolymérisation d'un ou de plusieurs prépolymères polysiloxanes aromatiques substitués avec un ou plusieurs monomères aromatiques, des monomères alkylés ou des monomères hydrophiles.
