ABSTRACT:
A system and method for cleaning, disinfecting, storing and wetting rigid gas permeable contact lenses is provided. The system includes a cleaning, disinfecting and storing solution and a separate wetting solution. Both solutions contain hydrophilic disinfectants or preservatives which do not inhibit proper wetting of rigid gas permeable contact lenses. The lenses are stored in the cleaning, disinfecting and storing solution during nonwearing periods. This storage also acts as a secondary or backup cleaning treatment to help remove any residual contaminants after the primary cleaning with this solution.
