This invention relates generally to disinfection and cleaning systems for medical devices. In a preferred embodiment, the invention relates to compositions, methods and articles for simultaneously cleaning and disinfecting contact lenses. The present invention is directed to ophthalmic compositions containing one or more block copolymers referred to as (polyoxyethylene)-(poly-oxybutylene) block copolymers (PEO-PBO). The invention is particularly directed to the use of PEO-PBO di-block copolymers as non-foaming wetting agents in peroxide-based compositions for disinfecting contact lenses.

There is disclosed a formulation suitable for the reduction or prevention of contamination of articles by microorganisms. The formulation includes at least one block copolymer of ethylene oxide and propylene oxide, at least one polyacrylic acid salt, and at least one propoxylated ethylenediamine compound.

Contact lens treatment systems and methods for disinfecting contact lenses are described. These systems and methods utilize a coated catalytic disc in combination with a fibrous catalyst. The coated catalytic disc contains a support disc and 6 to 300 mg of manganese present on at least a portion of the support disc, often in the form of manganese dioxide. The fibrous catalyst contains 25 to 50 mg iron, often in the form of an iron cation.

Contact lens treatment systems and methods for disinfecting contact lenses are described. These systems and methods utilize a coated catalytic disc, which contains a support disc and a manganese oxide present on at least a portion of the support disc. The coated catalytic disc contains 300 g to 1800 g of manganese, often in the form of manganese dioxide.
