PROCESS FOR HYDRATING SOFT CONTACT LENSES

摘要

According to a further broad aspect of the present invention there is provided a process for expediting and manufacture of a hydrogel contact lens suitable for insertion into the eye. The process comprises washing a hydrophilic polymeric contact lens in a series of processing stations to hydrate the lens and remove leachable species from the lens. The lens is then sealed in a final package for the lens with a buffered aqueous saline solution under conditions effective to neutralize the pH and osmolality of the lens to be compatible with that of the eye and to maintain hydration of the lens.
