摘要：
Silicone hydrogel ophthalmic devices, such as ocular inserts and contact lenses, formed in direct contact with molds comprising at least one vinyl alcohol copolymer and related methods are described. The at least one vinyl alcohol copolymer of the molds is a vinyl alcohol copolymer other than an ethylene-vinyl alcohol copolymer. The methods of manufacturing ophthalmic devices can use dry or wet demolding processes, or dry or wet delensing processes.
