摘要： There is described a method of removing excess lens forming material from a molded ophthalmic lens (1), such as the peripheral region of a contact lens. In order to form a lens (1) a lens forming material is polymerized and/or cross-linked within a mold cavity of a mold comprising female and male mold halves. The mold is opened by moving the female and male mold halves apart from each other. The formed lens (1) is supported on a carrier (3) such, that a front surface (2) of the lens (1) is exposed. Residues of non-polymerized and/or non-cross-linked lens forming material are removed mechanically by contacting the exposed surface (2) of the formed lens (1) for a period of time of about 0.5 seconds to about 4 seconds, preferably about 0.8 seconds to about 2 seconds, with a cleaner (7) having a hardness which is smaller than that of the polymerized and/or cross-linked lens forming material. There is also described a device (5) for carrying out the method.

摘要： 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 (4) of a mold (1) comprising female and male mold halves (2, 3) to form an ophthalmic lens non-polymerized and/or non-cross-linked lens forming material is flushed away from the mold halves (2, 3) with a jet of a fluid flushing medium, such as, e.g., water or a solvent or an inert gas. Subsequently the molded lens is dried. In accordance with the invention the flushing is accomplished with the mold halves (2, 3) still in the closed position. There is also described an apparatus for carrying out the method.

摘要： Surface treated implantable articles and related methods are disclosed. The surface treated implantable articles can be substantially flash-free, include one or more rounded edges, or include an enhanced optical clarity, one or all of which can be produced by polishing. The polishing can include causing the implantable articles to be repeatedly impacted with polishing media when the articles are swelled to an enlarged state. The polishing process can be particularly useful for smoothing lacrimal implants insertable in a lacrimal canaliculus.

摘要： The present contact lens treating systems and methods effectively remove extractable materials from contact lenses, for example, newly formed contact lenses, so that the lenses can be safely and conveniently worn, for example, for extended periods of time. Such treatment methods and the present extraction medium reprocessing methods allow lens treatment while reducing extraction medium losses, thereby reducing costs of these materials and the burden of such treatment on the environment. The present methods can also be useful for manufacturing a heat stabilized contact lens, for example, a water swelled contact lens including a Vitamin E component which is insoluble in the lens in a hydrated state.

摘要： A method of extracting residual materials from a polymeric, ophthalmic biomedical device, such as a contact lens, by using a mixture comprised of a primary solvent, such as carbon dioxide, and a polar co-solvent, such as isopropanol. By exposing the device to the co-solvent, the device expands. By pulsing or varying the concentration of the polar co-solvent in the mixture, the lens dimensions vary accordingly. When the lens is extracted while retained in a mold, the changes in lens dimensions causes the lens to be released from the mold.

摘要： The present invention is directed to a process for producing a powder free natural latex article and the articles produced by the process. In one embodiment, the process of the present invention may be used to form a powder free natural latex glove which has very low levels of extractable protein without being subjected to a halogenation processes. The process includes forming a natural rubber article on a former and then, either before or after stripping the article from the former, contacting the article with a rinse solution comprising the ionic species of a disassociated metal salt. In one embodiment, the metal salt may be sodium chloride. Contact with the rinse solution may lower protein levels in the latex. When the article is stripped from the former prior to contact with the rinse solution, the rinse solution may also remove any residual powders from the glove in order to produce a powder free natural rubber article. The non-chlorinated product may have good gripping characteristics and an extended shelf life when compared to similar chlorinated products.

摘要翻译：本发明涉及一种生产无粉末天然胶乳制品和通过该方法制备的制品的方法。在一个实施方案中，本发明的方法可用于形成无粉末天然乳胶手套，其具有非常低水平的可提取蛋白质而不经历卤化过程。该方法包括在前者上形成天然橡胶制品，然后在从前者剥离制品之前或之后，将制品与包含解离金属盐的离子种类的冲洗溶液接触。在一个实施方案中，金属盐可以是氯化钠。与冲洗溶液接触可能会降低胶乳中的蛋白质含量。当在与冲洗溶液接触之前将制品从前者中剥离时，冲洗溶液也可以从手套中除去任何残留的粉末，以便产生无粉末的天然橡胶制品。与类似的氯化产品相比，非氯化产品可能具有良好的夹持特性和延长的保存期限。

摘要： An apparatus and method for hydrating is provided for hydrating a lens and extracting residual materials from the lens. The apparatus includes a shaft; multiple arms extending radially from a lower end of the shaft about a central axis in a star-shaped pattern, each arm including a fin extending therebelow such that multiple fins also extend radially with respect to said central axis, wherein the fins including lower outer edges that converge and form a nozzle face. A fluid transport passage extends through the shaft and terminates at an opening in the nozzle face, whereby fluid can be evacuated from the lens through this passage. Preferably, at least one recessed channel is formed in the nozzle face where the fins converge, wherein each of these channels extends from the opening in the nozzle face that forms a terminus of the fluid transport passage to a space between two adjacent fins. The lower outer edges of the fins have an arcuate surface, the arcuate surfaces forming a convex-shaped nozzle face. Preferably, the outer tips of the arms extend radially from the central axis of the apparatus further than the fins extend.
