Claim:
1. A method of manufacturing an ophthalmic device, comprising: (a) providing at least one vinyl alcohol copolymer, (b) using the at least one vinyl alcohol copolymer to form at least one of a first mold member and a second mold member, the at least one of the first mold member and the second mold member comprising a device-forming molding surface having a static sessile drop contact angle less than 50 degrees and which is free of a plasma treatment, wherein the first mold member comprises a molding surface configured to mold an anterior surface of an ophthalmic device and the second mold member comprises a molding surface configured to mold a posterior surface of an ophthalmic device, and the first mold member and the second mold member are configured to form an ophthalmic device-shaped cavity therebetween when combined as a mold assembly; (c) placing a polymerizable composition comprising at least one hydrophilic monomer in the first mold member or the second mold member; (d) assembling the mold assembly by contacting the first mold member and the second mold member so as to form the ophthalmic device-shaped cavity therebetween with the polymerizable composition contained in the ophthalmic device-shaped cavity of the mold assembly; and (e) curing the polymerizable composition in the mold assembly to form a cast-molded polymerized reaction product in the ophthalmic device-shaped cavity of the mold assembly, the polymerized reaction product comprising a polymeric ophthalmic device body.
