摘要： A method, device and trays for transferring ophthalmic lenses from one work station to another. The first tray supports the lenses after release from the mold. The second tray supports the lenses during further processing including surface treatment. The articles are precisely placed and inverted as they are transferred from the first tray unto the second tray. Additionally, both sides of the ophthalmic lenses may be plasma reacted while supported on the second tray.

摘要： The present invention is directed to the surface treatment of silicone hydrogel contact lenses. In particular, the present invention is directed to a method of modifying the surface of a contact lens to increase its hydrophilicity by coating the lens with a carbon-containing layer made from a diolefinic compound having 4 to 8 carbon atoms. In one embodiment, an optically clear, hydrophilic coating is provided upon the surface of a silicone hydrogel lens by sequentially subjecting the surface of the lens to: a plasma oxidation reaction, followed by a plasma polymerization reaction in the presence of a diolefin in the absence of air. Finally, the resulting carbon layer is rendered hydrophilic by a further plasma oxidation reaction or by the attachment of a hydrophilic polymer chain.

摘要： Hydrogen-plasma modification of fluorinated polymers reduces the surface chemistry of this polymer removing fluorine, leaving behind a carbon-enriched surface that is further plasma processed into a hydrophilic surface for a lens material to be inserted into the ocular environment.

摘要： The present invention provides an optically clear, hydrophilic coating upon the surface of a silicone medical device by sequentially subjecting the surface of the lens to plasma polymerization reaction in a hydrocarbon atmosphere to form a carbon layer, and then graft polymerizing a mixture of monomers comprising hydrophilic monomers onto the carbon layer. The invention is especially useful for forming a biocompatible coating on silicone hydrogel contact lenses.
