Some solutions are used with two rarely used disinfecting
methods: heat and ultrasound. In the heat method, lenses are first cleaned, then placed in a lens
case containing saline solution. The lens case, in turn, is placed in a heating
apparatus to increase the temperature of the solution and kill germs. In the
ultrasound method, the solution undergoes cavitation, the rapid formation and
collapse of bubbles, to clean the lens. Ask your physician or pharmacist for
further information if you are interested in either of these methods.
