ABSTRACT:
A method for disinfection a device such as a contact lens. The method comprises contacting the device with an aqueous liquid medium containing an effective amount of chlorine dioxide at effective disinfecting conditions. The chlorine dioxide being derived by contacting a liquid medium containing chlorine dioxide precursor with a transition metal component in an effective amount to promote the generation of chlorine dioxide from the chlorine dioxide precursor. The liquid medium further optionally containing a buffer component in an amount effective to maintain the liquid medium at a desired pH during the generation of chlorine dioxide, and to increase the rate of chlorine dioxide generation from chlorine dioxide precursor relative to a similar liquid medium without the buffer component.
