    摘要： The invention provides a method of making ophthalmic lenses with an enhanced quality and enhanced yield achieved by using molds having been treated on back surface of mold with corona discharge technique. The method comprises the steps of obtaining a mold for cast-molding contact lenses from a lens formulation, wherein the mold comprises a first mold half having a first molding surface and a first back surface, a second mold half having a second molding surface and a second back surface, wherein when the first and second mold are configured to receive each other such that a lens forming cavity is formed between the first molding surface and the second molding surface and applying a corona discharge on one of the first and second back surfaces so that the molding surface of the mold with the treated back surface has an average water contact angle smaller than the molding surface of the mold with untreated mold by about 0.1 degrees to about 6 degrees.

    摘要： The invention provides a method for washing, with a water-based system, reusable molds for making silicone hydrogel contact lenses. The water-based washing system comprises an ethoxylated silicone polyether surfactant. The water-based system of the invention can effectively wash away silicone-containing components and other components of a lens formulation left behind on the molding surfaces of a reusable mold, after removing a silicone hydrogel contact lens cast molded in the reusable mold.

    摘要翻译： 本发明提供了用水基系统洗涤用于制造硅酮水凝胶隐形眼镜的可重复使用的模具的方法。 该水基洗涤体系包含乙氧基化有机硅聚醚表面活性剂。 在移除在可重复使用的模具中铸造成型的硅酮水凝胶隐形眼镜之后，本发明的水基系统可以有效地洗去留在可重复使用模具的模制表面上的含有硅氧烷的组分和其他组分。
