SILICONE-CONTAINING POLYMERIC MATERIALS WITH HYDROLYZABLE GROUPS

摘要

The invention provides a silicone hydrogel contact lens including a hydrolyzable units. The hydrolyzable units can be converted by hydrolysis into a hydrophilic units which is capable of imparting the silicone hydrogel contact lens a hydrophilic surface without post-curing surface treatment. The invention also provides an actinically crosslinkable prepolymer including hydrolyzable units and use of the prepolymer of the invention. In addition, the invention provides a method for making wettable silicone hydrogel contact lens without posterior surface treatments other than hydrolysis.
