ABSTRACT:
Enzyme compositions and methods employing enzyme compositions are disclosed which are useful for cleaning contact lenses. In one embodiment, a composition in accordance with the present invention comprises an enzyme component effective when released in a liquid medium to remove debris from a contact lens located in the liquid medium; and an activity regulating component effective when released in the liquid medium to deactivate the enzyme component located in the liquid medium. This composition is preferably structured so that the enzyme component is released in the liquid medium before the activity regulating component is so released. The period of time between the release of the enzyme component and the activity regulating component is sufficient to allow the enzyme component to effectively remove debris from a contact lens which is introduced into the liquid medium before or at the same time the enzyme component is released in the liquid medium.
