20090142292 | Method For The Mitigation of Symptoms of Dry Eye - A method for the mitigation of symptoms of dry eye is disclosed. The method involves at least (a) incorporating one or more non-functionalized polymers having one or more hydrophilic moieties into an ophthalmic device that is a polymerization product of a comonomer mixture comprising: (i) a major amount of a non-silicone-containing hydrophilic monomer; and (ii) an end terminal functionalized surfactant; and (b) inserting the ophthalmic device in the eye of a patient. | 06-04-2009 |
20090142485 | Process for Making Biomedical Devices - A process for treating a silicone hydrogel biomedical device, especially an ophthalmic lens such as a contact lens, involves: immersing the silicone hydrogel biomedical device with a mixture of an organic solvent and a hydrophilic, polymeric material, for a sufficient time that the device is swollen in volume by at least 30%; and removing the organic solvent from the device while retaining at least a portion of the hydrophilic polymeric material therein. | 06-04-2009 |
20100149482 | CONTACT LENS - Disclosed are silicone-containing contact lenses having an overall additive thickness less than or equal to about 310 μm. | 06-17-2010 |
20100315588 | Biomedical devices - Biomedical devices such as contact lenses formed from a polymerization product of a mixture comprising (a) a hydrophilic polymer comprising one or more hydrophilic units and one or more thio carbonyl thio fragments of a reversible addition fragmentation chain transfer (“RAFT”) agent; and (b) one or more biomedical device-forming monomers are disclosed. | 12-16-2010 |
20110015298 | PROCESS FOR MAKING CATIONIC HYDROPHILIC SILOXANYL MONOMERS - The present invention relates to polymeric compositions useful in the manufacture of biocompatible medical devices. More particularly, the present invention relates to certain cationic monomers capable of polymerization to form polymeric compositions having desirable physical characteristics useful in the manufacture of ophthalmic devices. Such properties include the ability to extract the polymerized medical devices with water. This avoids the use of organic solvents as is typical in the art. The polymeric compositions comprise polymerized cationic hydrophilic siloxanyl monomers prepared by the process disclosed herein. | 01-20-2011 |
20120157565 | Polymerizable Surfactants and Their Use as Device Forming Comonomers - This invention describes the use of polymerizable surfactants as comonomers in forming ophthalmic devices such as contact lenses, intraocular lenses, corneal implants, etc. | 06-21-2012 |
