PROCESS FOR THE PRODUCTION OF HIGH REFRACTIVE INDEX POLYSILOXANE-BASED POLYMERIC COMPOSITIONS FOR USE IN MEDICAL DEVICES

摘要

A process for producing polysiloxane prepolymers of improved homogeneity for use in the production of relatively high refractive index polymeric compositions is described herein. Polymeric compositions so produced are useful in the production of ophthalmic devices such as for example intraocular lenses and corneal inlays. The preferred polymeric compositions are produced through the copolymerization of one or more polysiloxane prepolymers with hydrosilane-containing polysiloxanes.
