Abstract: Methods and apparatus for additive manufacture of an article corresponding with an energy transmissibility image. The article may include a contact lens or intraocular lens. The improvements are directed to repeated application of a monomer according to a pattern corresponding with the energy transmissibility image, such as grayscale image. The method may include intermittent pinning of deposited polymerizable mixture, partial cure, and final cure of the deposited polymerizable mixture. A pattern of multiple defined areas may be manufactured, with each area representing an amount of energy transmissibility associated with that area.

Abstract: A method of providing a polymerized ophthalmic lens in which a polymerized ophthalmic lens is heated with a packaging solution comprising about 100 ppm to about 3,000 ppm of a wetting agent after its polymerization, and the ophthalmic lens formulation not having the wetting agent prior to its polymerization.

Abstract: This invention provides a contact lens comprising a front surface, a back surface and an identifying mark on at least one of said front surface and said back surface, wherein said identifying mark comprises a depressed region having a cross-section which comprises at least two intersecting concave surfaces at the bottom of said depressed region.

Abstract: An arrangement for molding a front or back polystyrene mold half which is used, with a second complementary back or front mold half, for subsequent molding of a soft contact lens such as a hydrogel soft contact lens. Each mold half defines a convex curved surface and a concave curved surface spaced therefrom, with one of the surfaces defining an optical quality curved surface for the soft contact lens. A heated molding machine introduces molten polystyrene through a hot runner system to a plurality of mold cavities, each of which defines an optical quality curved surface and also a second noncritical surface. The optical quality surface of the mold cavity is positioned further away from the heated hot runner side of the mold than the second surface, which allows faster cooling of the optical quality surface of the mold cavity. Each mold cavity has a first insert on the optical quality side of the mold cavity and a second insert on the second side.
