The invention provides a class of hydrophilized polydiorganosiloxane vinylic crosslinkers. Each of the hydrophilized polydiorganosiloxane vinylic crosslinkers of the invention comprise (1) a polydiorganosiloxane segment comprising dimethylsiloxane units and hydrophilized siloxane units each having one methyl substituent and one organic substituent having a phosphorylcholine moiety; (2) ethylenically-unsaturated groups. The invention also provides a silicone hydrogel contact lens, which comprises a crosslinked polymeric material comprising repeating units of at least one of such a class of hydrophilized polydiorganosiloxane vinylic crosslinkers. The invention further provides a method of producing a hydrophilized contact lens from a polymerizable composition comprising at least one of such a class of hydrophilized polydiorganosiloxane vinylic crosslinkers.
A hydrophilized polydiorganosiloxane vinylic crosslinker, comprising:
A silicone hydrogel contact lens, comprising a crosslinked polymeric material that comprises units of a hydrophilized polydiorganosiloxane vinylic crosslinker, wherein the hydrophilized polydiorganosiloxane vinylic crosslinker comprises:
