Abstract
Silicone hydrogel contact lenses having ophthalmically acceptable surface wettabilities are obtained from pre-extracted polymerized silicone hydrogel contact lens products having relatively large amounts of removable or extractable materials. The silicone hydrogel contact lenses can be obtained from non-polar resin based contact lens molds and without surface treatments or an interpenetrating polymeric network of a polymeric wetting agent. Related lens products, polymerizable compositions, and methods are also described.
