Patent number: 11111055Abstract: 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.Type: GrantFiled: December 11, 2018Date of Patent: September 7, 2021Assignee: Alcon Inc.Inventors: Daryl Reece, Uwe Haken, Honghui Lu, Oli Jobe, Alice Weimin Liu

Patent number: 9919456Abstract: The invention provides a method for producing ophthalmic lenses, preferably contact lenses, more preferably silicone hydrogel contact lenses. This method involves applying a coat of catanionic vesicles onto the molding surfaces of a mold. By having a coat of catanionic vesicles on the molding surfaces of a mold, mold separation force and lens defects generated during mold opening and de-molding process can be substantially reduced.Type: GrantFiled: October 30, 2014Date of Patent: March 20, 2018Assignee: Novartis AGInventors: Horngyih Huang, Honghui Lu

Patent number: 9802339Abstract: The instant invention pertains to a method and a fluid composition for producing contact lenses with improved lens quality and with increased product yield. The method of the invention involves applying to a molding surface of the mold a layer of mold releasing agent selected from a group consisting of fatty amines of carbon chain length C18 or less and silicones bearing pendant substituted pyrrolidone groups solution to reduce an averaged mold separation force by at least about 50% in comparison with that without the releasing agent.Type: GrantFiled: December 11, 2014Date of Patent: October 31, 2017Assignee: Novartis AGInventors: Arturo Norberto Medina, Jinyu Huang, Katherine Ard, Honghui Lu, Uwe Haken

Patent number: 9623589Abstract: There is described a process for manufacturing an ophthalmic lens and an apparatus for forming an ophthalmic lens, in particular a silicone hydrogel contact lens, wherein in a mold assembly a first and a second mold half (101, 102) are first arranged in an intermediate closed position in which the mold surfaces of the two mold halves are spaced apart from each other at a distance increase (d1) of preferably 1 to 100 ?m relative to a final distance (d0) in a final closed position, and wherein, during curing of the lens forming material (202), the mold surfaces (105, 106) of the mold halves (101, 102) are actively or passively moved or moving from the intermediate closed position to the final closed position, where the distance increase (d1) is 0.Type: GrantFiled: November 7, 2013Date of Patent: April 18, 2017Assignee: Novartis AGInventors: Roger Biel, Gabriela Cocora, Peter Hagmann, Uwe Haken, William Jordan Hall, Axel Heinrich, Günter Lässig, Honghui Lu, Deborah J.
