摘要： An apparatus and method for directing accelerated electrons to at least part of one surface of one ophthalmic mold piece prior to filling with monomer and lens polymerization. In particular it has been found that generation of the ionized oxygen by means of a corona treatment electrode sufficiently increases the adherence of the polymer to the mold piece so treated. In the preferred embodiment, the flange around the convex, male piece of the lens mold is corona treated so that when the mold pieces are separated after lens polymerization, the flashing of excess polymerized material surrounding the lens cavity adheres to that male, convex piece flange while the lens is removed with the female, concave piece.

摘要： An apparatus for causing the polymerized excess monomer to separate from a molded lens by increasing the surface energy of the flange area of one mold piece, causing the polymerized excess monomer to stick thereto. Specifically when manufactured under inert atmosphere conditions, a particular manifold is needed to supply an oxygen bearing gas, air, to the area to be treated while preventing the oxygen from contaminating the lens manufacturing area of the molds or diluting the nitrogen atmosphere of other lens process areas. It has been found that generation of the ionized oxygen by means of a corona treatment electrode sufficiently increases the adherence of the polymer to the mold piece so treated. In the preferred embodiment, the flange around the convex, male piece of the lens mold is corona treated so that when the mold pieces are separated after lens polymerization, the flashing of excess polymerized material surrounding the lens cavity adheres to that male, convex piece flange while the lens is removed with the female, concave piece.

摘要： An improved method is disclosed of imparting a tint or color to a soft, hydrogel contact lens by uniformly dispersing a dye throughout the lens. The dye is composed of a water-soluble compound essentially free of ethylenic unsaturation. A homogeneous solution of the dye in a hydrophilic monomer is prepared, the solution is subjected to polymerization conditions to yield a hydrophilic polymer from which the lens is formed, and the dye dispersed within the polymer is bonded to the polymer by contact with aqueous base prior to final hydration.The finished lens does not require soaking in an aqueous solution of the dye to impart the desired tint or color to the lens. Additionally, the dye uniformly dispersed throughout the lens according to the improved method does not leach out of the lens or migrate within the lens.
摘要翻译：公开了一种改进的方法，通过使染料均匀地分散在整个透镜中，将柔软的水凝胶隐形眼镜赋予着色或着色。染料由基本上不含烯属不饱和键的水溶性化合物组成。制备染料在亲水单体中的均匀溶液，使溶液经受聚合条件以产生形成透镜的亲水聚合物，并且分散在聚合物内的染料通过与碱水溶液接触而与聚合物结合最终水化。成品镜片不需要在染料的水溶液中浸泡以赋予镜片所需的色调或颜色。此外，根据改进的方法均匀分散在整个透镜中的染料不会从透镜中浸出或在透镜内迁移。

摘要： A rotational indexing base curve deposition array for assembling contact lens base curves and front curves with a prescribed and programmable angular orientation to produce a contact lens having a selected axis placement therein, such as a toric axis for a toric contact lens. An array of front curve molds are arranged in a support pallet with a dosed amount of monomer mixture deposited into each of the front curve molds. An array of deposition tubes, positioned in a support plate and coupled to a vacuum source, is used to pick up and support an array of base curve molds. Each of the deposition tubes is then angularly rotated in to the support plate to a selected angularly indexed position therein. A common angular rotational drive is coupled to each of the deposition tubes in the array to angular index each of the deposition tubes to a precise angular position in the support plate. The common angular rotational drive is driven by a stepper motor which can be controlled in a programmable manner to change the selected angularly indexed position. The stepper motor drives moveable racks, which drive pinion gears around the deposition gears. The angularly indexed array of base curve molds is then assembled over the array of front curve molds to produce toric lenses having first and second optical surfaces which are precisely angularly indexed relative to each other.
