Abstract: An apparatus for the plasma treatment of molds (2), in particular for contact lens molds, comprises a treatment chamber (50), in which a first electrode (51) is arranged facing a carrier (1;4) for carrying the molds (2) to be treated. The carrier (1;4) forms the second electrode (52) and comprises a first metal plate (10;40) having holes (100;400) therein and a second metal plate (11;41) which is arranged spaced apart from the first metal plate (10;40), and which is connected to the first metal plate (10;40) in an electrically conductive manner (12,13;43). The molds (2) are arranged on the second metal plate (11;41) with their molding surfaces (210) facing towards the first electrode (51) and are exposable to plasma through the holes (100;400) in the first metal plate (10;40).

Abstract: The present invention relates to a method for the manufacture of a contact lens with a printed image thereon, in particular a silicone hydrogel contact lens with a printed image thereon, comprising applying one or more ink drops to at least a portion of at least one molding surface of a lens mold, wherein each ink drop is sufficiently flat, that the forces exerted by the mold surface to the ink drop surface in the area where they make contact, are higher than the forces exerted by the flowing lens forming material to the facing surface of the ink drop, and wherein the ink material and the lens forming material are sufficiently immiscible or not miscible at all.

Abstract: 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.

Abstract: The present invention generally relates to a printing apparatus including one or more print heads for depositing printing fluid onto a substrate, wherein the apparatus comprises a maintenance unit for the one or more print heads. The present invention further relates to a method for cleaning one or more print heads from adhering printing fluid. The present invention also relates to the use of said apparatus in the automated manufacture of a contact lens, in particular a silicone hydrogel contact lens.
