| 20090188525 | Apparatus, carrier and method for the plasma treatment of molds - An apparatus for the plasma treatment of molds ( | 07-30-2009 |
| 20090295002 | Process 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 |
| 20100155975 | MOLD RELEASE SHEET - The present invention relates to a mold half for making an ophthalmic lens, in particular a contact lens, wherein the mold half comprises a release sheet removably arranged on the mold surface of said mold half to separate a lens forming material from the mold surface, as well as to a method for applying a removable mold release sheet to said mold half. The mold half of the invention comprises a vacuum means to removably attach said release sheet to said mold surface, and preferably the mold half further comprises a pinch-off rim for forming the edge of said ophthalmic lens. | 06-24-2010 |
| 20100309251 | MAINTENANCE UNIT FOR PRINT HEAD - 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. | 12-09-2010 |
| 20110089585 | Method for the Simultaneous Manufacture of Ophthalmic Lenses, in Particular Contact Lenses, with Different Parameters on the Same Production Line - There is described a method for the simultaneous manufacture of contact lenses having different lens parameters on the same production line, where a number of molds, each comprising male and female mold halves, are transported in sequential rows of and in each row in side by side configuration through a series of treatment stations, which are arranged sequentially along a production line, in which lenses of specific parameters are manufactured from a lens forming material. During manufacture each lens is associated with a lens identification code. There is also described a closed cycle production line for carrying out the method. | 04-21-2011 |
| 20110089586 | Process 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 |
| 20110101552 | METHOD FOR MAKING A COLORED CONTACT LENS - 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. | 05-05-2011 |
| 20110147956 | METHOD OF DOSING A LENS FORMING MATERIAL INTO A MOLD - There is described a method of dosing a lens forming material into a mold ( | 06-23-2011 |
| 20110147957 | PROCESS AND APPARATUS FOR DISPENSING A FLOWABLE MATERIAL INTO A MOLD - A process for dispensing a flowable material including a volatile solvent into a mold, in particular a material for forming an ophthalmic lens, e.g. a contact lens, is disclosed. The process includes the steps of providing a mold; providing a dispenser; arranging the mold underneath the dispenser; dispensing the flowable material including the volatile solvent into the mold, the step of dispensing being performed in a local gas atmosphere substantially preventing the solvent from evaporating from the flowable material. | 06-23-2011 |
| 20110147959 | METHOD 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 |
| 20110147960 | METHOD OF REMOVING EXCESS LENS FORMING MATERIAL FROM A MOLDED OPHTHALMIC LENS SUCH AS A CONTACT LENS - There is described a method of removing excess lens forming material from a molded ophthalmic lens ( | 06-23-2011 |
