发明名称 Contact lens extraction/hydration systems and methods of reprocessing fluids used therein
摘要 The present contact lens treating systems and methods effectively remove extractable materials from contact lenses, for example, newly formed contact lenses, so that the lenses can be safely and conveniently worn, for example, for extended periods of time. Such treatment methods and the present extraction medium reprocessing methods allow lens treatment while reducing extraction medium losses, thereby reducing costs of these materials and the burden of such treatment on the environment. The present methods can also be useful for manufacturing a heat stabilized contact lens, for example, a water swelled contact lens including a Vitamin E component which is insoluble in the lens in a hydrated state.
