Abstract
This invention is directed to an aqueous composition and methods for clean lipid deposits on contact lenses. In particular, a combination of non-ionic surfactants, branched and/or straight poly(ethylene oxide-propylene oxide) (PEO-PPO) block copolymers having HLB value greater than or equal to 18, with an additional straight poly(ethylene oxide-propylene oxide) (PEO-PPO) block copolymers having HLB value less than or equal to 15, has been found to improve the lipid cleaning properties of an aqueous composition for contact lenses and prevent the overgrowth of harmful bacteria, yeast and molds without adversely affecting the comfort or safety in terms of the level of toxicity to eye tissue.
