METHOD FOR TREATING EXTENDED-WEAR CONTACT LENSES IN THE EYES

摘要

The present invention is directed to a method for treating a silicone-hydrogel contact lenses while worn in the eye. In particular, the method employs an ophthalmic solution containing a cationic cellulosic polymer that binds to the lens and prevents the accumulation of lipids, proteins and other products, particularly during extended use of the lens. The addition of one or more surfactants to the solution further maintains the lens clean during use. Such a solution is intended to be applied, in the form of drops, to contact lens in the eye.
