More Information
Summary:Ophthalmic device molds made from at least one highly amorphous vinyl alcohol polymer, ophthalmic devices such as ocular inserts and contact lenses and including silicone hydrogel devices formed using these molds, and related methods are described. The methods of manufacturing ophthalmic devices can use dry or wet demolding processes, or dry or wet delensing processes.
