Patent ID: 8079703

Claim:
A soft contact lens, comprising: a silicone hydrogel material that is obtained by curing a lens-forming material in a mold and comprises first and/or second hydrolyzable silicone-containing groups, wherein the lens-forming material comprises at least one actinically crosslinkable monomer having one first hydrolyzable silicone-containing group and/or at least one actinically crosslinkable prepolymer having multiple second hydrolyzable silicone-containing groups, wherein the first and second hydrolyzable silicone-containing groups are cleaved from the silicone hydrogel material by means of hydrolysis and the soft contact lens has a water contact angle of about 90 degrees or less without post-curing surface treatment, wherein the silicone hydrogel material comprises polymeric units derived from a vinylic monomer of formula (1) or (2) in which 1 R is H or —CH 3 , -L- is —O— or 2 R is trimethylsilyl group (—Si(CH 3 ) 3 ) or a C 4 -C 25 alkyl which is substituted by at least one trimethylsilyloxy, trimethylsilylamino group or trimethylsilyl-C 1 -C 7 alkylamino group, 3 R is H or C 1 -C 8 alkyl group, in which 1 R is H or —CH 3 , -L- is —O— or 3 R is H or C 1 -C 8 alkyl group, 4 R is C 1 -C 12 unsubstituted alkylene (divalent radical) or substituted alkylene in which one or more hydrogens are substituted by C 1 -C 3 alkoxy groups, hydroxy groups, amino groups, thiol groups, and/or carboxyl groups, 5 R is C 1 -C 7 alkylene group.
