Optically transparent, relatively high refractive index polymeric compositions and ophthalmic devices such as intraocular lenses, contact lenses and corneal inlays made therefrom are described herein. The preferred polymeric compositions are produced through the polymerization of one or more aromatic- based silyl monomers or the copolymerization of one or more aromatic-based silyl monomers with one or more aromatic or non-aromatic non-siloxy-based monomers, hydrophobic monomers or hydrophilic monomers.

L'invention concerne des compositions polymères transparentes au niveau optique, à indice de réfraction relativement élevé, ainsi que des dispositifs ophtalmiques tels que lentilles intra-oculaires, lentilles de contact et incrustations cornéennes en profondeur fabriqués à partir de ces compositions. De préférence, ces compositions polymères sont produites par polymérisation d'au moins un monomère silyle à base aromatique ou par copolymérisation d'au moins un monomère silyle à base aromatique avec au moins un monomère à base non siloxy aromatique ou non aromatique, monomère hydrophobe ou monomère hydrophile.
