Abstract
Contact lens care compositions for the treatment of hard contact lenses are disclosed. The compositions are useful for rinsing, cleaning, disinfecting and storing of hard contact lenses. The compositions contain an unique gelling system involving galactomannan polysaccharides and borates to allow for the conditioning of the lens when it is reinserted in the eye of the user. Methods of using these compositions are also disclosed.
