Optically transparent, relatively high refractive index polymeric compositions and ophthalmic devices such as intraocular lenses, corneal inlays and contact lenses made therefrom are described herein. The preferred polymeric compositions are produced through the polymerization of one or more aromatic- based siloxane macromonomers or the copolymerization of one or more aromatic- based siloxane macromonomers with one or more non-siloxy aromatic-based monomers, non-aromatic-based hydrophobic monomers or non-aromatic-based hydrophilic monomers.
L'invention concerne des compositions polymères à index de réfraction relativement élevé, optiquement transparentes, et des dispositifs ophtalmiques notamment des lentilles intraoculaires, des implants cornéens et des lentilles de contact fabriqués à partir de ces compositions. Les compositions polymères préférées sont produites par la polymérisation d'un ou de plusieurs macromonomères de siloxane à base aromatique, ou par la copolymérisation d'un ou de plusieurs macromonomères de siloxane à base aromatique avec un ou plusieurs monomères à base aromatique non siloxy, des monomères hydrophobes à base non aromatique ou des monomères hydrophiles à base non aromatique.
