Abstract: The invention provides a method for producing embedded contact lenses involving steps of use of a set of 3 mold halves in two-curing steps. One of the 3 mold halves have been used twice, the first time for molding an insert and the second time for molding the embedded hydrogel contact lens. The twice-used mold half has been treated with a corona plasma or a vacuum UV in a central circular area of its molding surface having a diameter equal to or smaller than the diameter of the insert to ensure that the molded insert consistently adhered to the twice-used mold half. The method also comprises a step of forming a reactive polysiloxane coating that is covalently attached onto the back or front surface of a molded insert adhered on the twice-used mold half before molding the embedded contact lens in the 2nd curing step.

Abstract: The invention provides an easy-to-remove water gradient contact lens. Such a water gradient contact lens comprises imperfections (ditches and/or gaps) in the anterior outer hydrogel layer and can be made according to a cost-effective method involving a step of partially or completely shielding reactive functional groups in selected zones on the anterior surface a to-be-coated contact lens before grafting a layer of a non-silicone hydrogel material. With the imperfections in the anterior outer hydrogel layer, the surface lubricity of the anterior surface is inferior to that of the posterior surface. By adjusting the shape, size, density, and rotational distribution of the imperfections, one also can selectively adjust and optimize the surface lubricity of the anterior surface of a water gradient contact lens so as to have improved lens handlability while maintaining other desirable properties.

They can find particular use in producing water-soluble highly-branched hydrophilic polymeric material and in producing water gradient contact lenses.
