Patent application numberDescriptionPublished
20080249381Combined Apparatus For Measuring the Blood Glucose Level From an Ocular Fluid - A combined apparatus for measuring the blood glucose level from an ocular fluid comprises a hand-held fluorescence photometer (D10-09-2008
20090160074Method for making contact lenses - 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.06-25-2009
20090295002Process for the manufacture of an ophthalmic lens - A process for the manufacture of an ophthalmic lens, e.g. a contact lens, comprises the steps of:12-03-2009
20100276823METHOD FOR MAKING CONTACT LENSES - 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.11-04-2010
20100276824METHOD FOR MAKING CONTACT LENSES - 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.11-04-2010
20100296049ACTINICALLY-CROSSLINKABLE SILOXANE-CONTAINING COPOLYMERS - The invention provide a class of actinically-crosslinkable silicone-containing prepolymers which comprise dangling polysiloxane chains each having a terminal ethylenically-unsaturated group and are obtained in a one-step of RAFT polymerization of a reactive mixture comprising a polysiloxane crosslinker, a hydrophilic vinylic monomer, a RAFT agent, and a free-radical initiator. The present invention is also related to silicone hydrogel contact lenses made from a prepolymer of the invention and methods for making the contact lenses in a cost-effective way and with high consistency and high fidelity to the original lens design.11-25-2010
20110057337PLASTIC CASTINGS MOLDS - The invention is concerned with the problem that with known plastic casting moulds, especially those of polypropylene, the lenses produced with these moulds have a slippery surface. The invention solves this problem through the use of polymers which are notable for their very low oxygen permeability.03-10-2011
20110089586Process For Manufacturing An Ophthalmic Lens - 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 (04-21-2011
20110147959METHOD OF SEPARATING EXCESS LENS FORMING MATERIAL FROM A MOLDED OPHTHALMIC LENS, IN PARTICULAR A CONTACT LENS - There is described a method of separating excess lens forming material from a molded ophthalmic lens, in particular a contact lens. After polymerization and/or cross-linking of a lens forming material (P) within a mold cavity (06-23-2011
