Patent ID: 8231218

Claim:
A polymerizable silicone hydrogel contact lens precursor composition, comprising: a polymerizable non-silicon-containing component combined with a polymerizable silicon-containing component as a polymerizable silicone hydrogel contact lens precursor composition, a portion of the polymerizable silicone hydrogel contact lens precursor composition being removable from a polymerized silicone hydrogel contact lens product produced from the polymerizable silicone hydrogel contact lens precursor composition, and being present in an amount of at least 10% (w/w) of the polymerized silicone hydrogel contact lens product, wherein said portion has unreacted monomer, partially reacted monomer, or both in an amount that is at least 10% (w/w) based on the weight of the polymerized silicone hydrogel contact lens product.
