IMPROVED CLEANING AND CONDITIONING SOLUTIONS FOR CONTACT LENSES AND METHODS OF USE

摘要

Contact lens cleaning compositions comprising preserved surfactant-containing solutions of a poly(oxypropylene)-poly(oxyethylene) adduct of ethylene diamine having a molecular weight from about 7500 to as high as 27,000 wherein at least 40 weight percent of the adduct is poly(oxyethylene) hydrophilic units. The solutions are effective in removing protein/lipid tear film deposits on both hard and soft contact lenses while providing a prophylactic-like action in retarding the formation of subsequent tear film deposits. The compositions provide effective cleaning and conditioning action using both ambient and high temperature disinfection methods.
