Kind Code:
A
Abstract:
A method of increasing the shelf life of silicone hydrogels stored in aqueous solutions. More specifically, the present invention relates to a method of stabilizing a silicone hydrogel article against hydrolytic degradation comprising, storing said silicone hydrogel in an ozone-free, aqueous solution having a pH of from about 5.0 to less than about 7.2, and a viscosity of less than about 10 centipoise, wherein if the aqueous solution is substantially free of poloxamine or poloxamer surfactants.
