Abstract
A method for simultaneously cleaning and disinfecting contact lenses includes forming a disinfection solution containing an ophthalmically safe amount of a disinfecting agent, such as polyhexamethylene biguanide, and providing an effective amount of a proteolytic enzyme, such as subtilisin A. The disinfecting agent and proteolytic enzyme are selected such that in the working solution, the disinfection efficacy of the disinfecting agent is at least maintained. Preferably, after cleaning and disinfection, the lens can be rinsed with the disinfection solution, whereby the lens may then be directly inserted in the eye of the contact lens user without further rinsing.
