Abstract
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.
