Abstract: The invention provides a method for producing ophthalmic lenses, preferably contact lenses, more preferably silicone hydrogel contact lenses. This method involves applying a coat of catanionic vesicles onto the molding surfaces of a mold. By having a coat of catanionic vesicles on the molding surfaces of a mold, mold separation force and lens defects generated during mold opening and de-molding process can be substantially reduced.

Abstract: The instant invention pertains to a method and a fluid polymerizable composition for producing contact lenses with improved lens quality and with increased product yield. The method of the invention involves adding a water soluble and/or water dispersible quaternary ammonium cationic group containing silicone surfactant into a fluid polymerizable composition including a lens-forming material in an amount sufficient to reduce an averaged mold separation force by at least about 30% in comparison with that without the water soluble and/or water dispersible quaternary ammonium cationic group containing silicone surfactant.

Abstract translation: 本发明提供了一种用于制造眼镜片的方法，优选为隐形眼镜，更优选硅酮水凝胶隐形眼镜。 该方法包括在模具的模制表面上施加一层阴离子囊泡。 通过在模具的模制表面上具有一层阴离子囊泡，可以显着减少模具打开和脱模过程中产生的模具分离力和晶片缺陷。
