Low oxygen molding of soft contact lenses

摘要

The present invention provides a process for providing essentially fully degassed complementary concave and convex lens molds to filling and mold assembly stations, respectively, in a continuous or semicontinuous automated soft contact lens manufacturing system comprising injection molding said lens molds, immediately transferring said lens molds to an inert gas atmosphere, degassing said lens molds, and filling said lens molds with a polymerizable monomer under said inert gas prior to mold assembly. <IMAGE>
