Abstract
Official abstract text for this publication.
Ophthalmic device molds made from at least one vinyl alcohol copolymer and having a static sessile drop contact angle of less than 70 degrees, 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.
First claim
Opening claim text (preview).
What is claimed is: 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 t…
