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 optiquement transparentes et à indice de réfraction relativement élevé et des dispositifs ophtalmiques, tels que des lentilles intraoculaires, des incrustations cornéennes et des lentilles de contact conçues à partir de ces compositions. Les compositions polymères préférées sont obtenues par polymérisation d'un ou plusieurs macromonomères de siloxane à base aromatique ou par copolymérisation d'un ou de plusieurs macromonomères de siloxane à base aromatique avec un ou plusieurs monomères à base aromatique non-siloxy, un ou plusieurs monomères hydrophobes à base non aromatique ou un ou plusieurs monomères hydrophiles à base non aromatique.
