ABSTRACT:
Method for sterilizing soft contact lenses and the like using methoxymethane while the lenses are in a liquid-wetted state. Methoxymethane on the water-wet surface for a sufficient time kills the microorganisms (bacteria, molds and yeasts) that invade and are entrapped in the pores and irregular surfaces of the hydrophilic materials from which such soft contact lenses are made. An easily portable apparatus for applying this sterilization technique to the lenses is also disclosed. It includes a lens holder that can be held in a chamber that can be pressure-isolated to receive the methoxymethane gas from portable sources. In one form, an indicator shows that the lenses are under sterilization pressure. This novel arrangement dispenses with the inconvenience of using prolonged steaming, or questionable sterilization in disinfecting fluids which may affect the composition of the soft contact lens.
