A method for manufacturing a silicone hydrogel contact lens is described that comprises curing a polymerizable composition comprising at least one siloxane monomer and at least one hydrophilic vinyl-containing monomer in a contact lens mold comprising a molding surface having a coating comprising a hydrophilic polymer. The hydrophilic coating is not solubilized by the polymerizable composition during the curing step. The resulting polymeric lens body is removed from the mold, washed to remove any of the hydrophilic polymer that may have transferred from the mold surface to the lens during the curing or lens removal process, and packaged to provide a silicone hydrogel contact lens having a contact angle that is lower than what it would otherwise be had the lens been cured in the same contact lens mold lacking the hydrophilic coating.

Method of manufacturing wettable silicone hydrogel contact lenses

A method is provided for manufacturing ophthalmically-acceptable, distortion-free silicone hydrogel contact lenses without the use of volatile organic solvents in the manufacturing process. The contact lenses are extract with an extraction liquid comprising an aqueous solution of a non-volatile organic solvent, such as ethyl lactate.
