Abstract
Compositions and methods for disinfecting contact lenses are disclosed. In one embodiment, the present compositions include a liquid medium containing chlorine dioxide precursor in an amount effective to form, when activated, a chlorine dioxide-containing composition including a contact lens disinfecting amount of chlorine dioxide. A polyanionic component, preferably a water soluble polyanionic component, is included in the composition in an amount effective to inhibit the formation of proteinaceous deposit material on a contact lens immersed in the chlorine dioxide-containing composition. Thus, effective contact lens disinfection is achieved while, at the same time, reducing the risk of forming proteinaceous deposit material on the contact lens during the disinfecting processing.
