Abstract:
1. A sterile, aqueous solution for treating contact lenses, comprising: (a) an amount of a NIPAM polymer effective to inhibit the formation of protein deposits on said lenses and sufficient to provide said solution with a surface tension of less than 50 mnM −1 at a temperature of 23° C.; (b) an ophthalmically acceptable vehicle for said NIPAM polymer; and (c) an opthalmically acceptable antimicrobial agent in an amount effective to disinfect contact lenses, said solution having a physiologically compatible pH and an osmolality of 200 to 400 mOsm/kg, characterized in that, when said solution is applied to the surfaces of a contact lens, the adsorption of lysozyme to said surfaces following such application is inhibited.
