Use of surfactants in extraction procedures for silicone hydrogel ophthalmic lenses |
| abstract |
METHODS OF PRODUCING SILICONE HYDROGEL OPHTHALMIC LENSES INCLUDE CONTACTING ONE OR MORE DELENSED SILICONE HYDROGEL OPHTHALMIC LENS WITH A LIQUID COMPOSITION THAT CONTAINS ALCOHOL, WATER, AND A SURFACTANT. THE METHODS CAN BE STEPS OF AN EXTRACTION/HYDRATION PROCEDURE (112,114) USED IN THE PRODUCTION OF SILICONE HYDROGEL CONTACT LENSES. IN SOME EXAMPLES, CONTACTING SILICONE HYDROGEL OPHTHALMIC LENS PRODUCTS WITH A LIQUID COMPOSITION THAT CONTAINS ALCOHOL, WATER, AND A SURFACTANT CAN SIGNIFICANTLY REDUCE OR PREVENT SURFACE DISTORTION OF THE OPHTHALMIC LENS RESULTING FROM THE EXTRACTION PROCEDURE. SOME METHODS INCLUDE SUBSEQUENTLY CONTACTING THE SILICONE HYDROGEL OPHTHALMIC LENS WITH A LIQUID COMPOSITION CONSISTING ESSENTIALLY OF WATER AND A SURFACTANT. |
