摘要： 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 adding a phospholipid into a fluid composition including a lens-forming material in an amount sufficient to reduce an averaged mold separation force by at least about 40% in comparison with that without the phospholipids.

摘要： An apparatus and method for the production of ophthalmic lenses, and particularly contact lenses, which minimizes damage of the lens in removal from the mold. The ophthalmic lens is produced in a mold having a male part and a female part that are placed in proximate relation to each other to create a lens-forming cavity. At least the female surface of the female part mold is preferably coated with plasma and is irradiated for a predetermined time such that the female surface and/or surface coating is at least partially cured. Once the female surface, and alternately the male surface and other surfaces of the mold, is at least partially cured, a curable lens-forming material is placed into the lens-forming cavity and cured to form an ophthalmic lens.

摘要： The invention relates to a process for the manufacture of a molding comprising the steps of a) preparing an aqueous solution comprising a water-soluble prepolymer having crosslinkable groups and a further polymer which is devoid of crosslinkable groups, b) introducing the solution obtained into a mold, c) triggering the crosslinking, and d) opening the mold such that the molding can be removed from the mold. According to the process of the invention moldings such as contact lenses may be manufactured with an improved quality and an improved overall yield.

摘要： The present invention describes novel statistical copolymers and the preparation and possible uses thereof. Copolymers are described that are water-soluble and cross-linkable and that comprise the copolymerisation product of a monomer mixture consisting substantially of a vinyl lactam (a) and at least one further vinyl monomer (b) of a different type selected from the group consisting of hydrophobic, hydrophilic and functional vinyl monomers, wherein the monomers are present in the copolymer in the form of statistically distributed building blocks, and, if a functional vinyl monomer is present as a building block in the copolymer, that building block is, where appropriate, modified with a reactive vinyl monomer (c), the reactive vinyl monomer (c) being linked to a building block of a functional vinyl monomer with retention of its vinylic group and with the formation of a covalent bond.
