Abstract
The invention is directed to compositions and methods used as in-the-eye and/or out-of-eye inhibitors of proteinaceous deposits on hydrophilic contact lenses. Compositions of the present invention comprise moderately charged polyquaternium polymers that selectively bind to hydrophilic contact lenses to block the binding of proteinaceous materials. Compositions of the present invention may be used in multipurpose cleaning solutions for contact lenses and can eliminate the need for special enzyme cleaners and the like for removing proteinaceous materials.
