ABSTRACT:
A rapid cleaning and disinfecting method and composition for ophthalmic devices, e.g. contact lenses. The composition includes, on a weight basis, 10-50% of a C.sub.3-8 alkylene glycol, 2-30% of a lower alkanol, 2-15% of a surfactant, 0-2% pH adjusting agent, 0-5% tonicity builder, viscosity enhancing agent in an amount from 0 to the amount required to bring the solution viscosity to 100 cps, and the balance water. The method involves mechanically rubbing the ophthalmic device with the cleaning/disinfecting composition followed by rinsing the device.
