Silicone hydrogel contact lenses and methods for producing silicone hydrogel contact lenses

摘要

A method of manufacturing a silicone hydrogel contact lens comprising forming a silicone hydrogel contact lens body having an anterior surface and a posterior surface, in which the lens body has not been subjected to a form of plasma treatment, the lens body has not been treated with a polymerizable swelling agent after forming the lens body, or both, characterized in that after hydration of the lens body in water or an aqueous solution, at less one of the anterior surface and the posterior surface of the lens body, when wet, comprises a variety of depressions with at least one of an average diameter between 150 nanometers and less than 1500 nanometers and an average density of 100 depressions per 900 μm2 at 1200 depressions per 900 μm2.
