An embodiment of the invention is a basket for holding contact lenses. The basket comprises a first basket and a second basket mating members, each basket member includes a basket wall defining a first cavity, a planar flange extending out around the first cavity, a plurality of spaced fingers extending upward circumferentially from the periphery of the cavity, wherein the first basket and second basket mating members having a same structure, wherein the first basket and second basket mating members forming a second cavity when mated for receiving said contact lens, the cavity inhibiting inversion or rolling over of said contact lens when emplaced therein. A tray that comprises a plurality of baskets is another embodiment of the invention. In addition, the invention provides a stack assembly that comprises a plurality of trays each of which comprises a plurality of baskets.

Basket for carrying a contact lens during its treatment in a bath

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.
