ABSTRACT:
Improved contact lens compositions are achieved through incorporation of a fluorine containing mono or diester of itaconic acid in siloxane polymeric contact lens compositions. Copolymers include components which modify contact lens mechanical, optical and transport properties as well as surface characteristics to achieve at least some compositions having an oxygen permeability of at least DK35 with a refractive index of from 1.35 to 1.5 and a percent hydration below 2 percent of total weight. Contact lenses made of materials of this invention are highly permeable to oxygen and resistant to the deposition of tear components providing extended wear capability through improved biocompatibility.
