Abstract
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 siloxysilane monomers or the copolymerization of one or more siloxysilane monomers with one or more aromatic or non-aromatic non-siloxy monomers, hydrophobic monomers or hydrophilic monomers.
