Abstract

Compositions are provided for the effective cleaning of soft and silicone contact lenses by soaking the lenses for a time sufficient to remove adherent residues in a solution containing an epoxy modified silicone surfactant and a fatty acid amide (or nitrogen analog thereof) surfactant, which may be cationic or non-ionic. Other additives may also be included such as thickening agents, bactericides, salts, anionic surfactants, and the like. The compositions are found to be particularly effective in removing strongly adhering proteinaceous matter, as well as lipids and polysaccharides.
