A method of treating contact lenses made from polymerizable materials by providing supercritical fluids to the lenses.

Treatment of contact lenses with supercritical fluid

A mold assembly includes first and second mold sections having respective first and second mold cavity defining surfaces, the first mold cavity defining surface terminating in an encircling peripheral rim and the second mold cavity defining surface terminating in a deformable peripheral annulus disposed at a diameter corresponding to the rim, and cooperating tapers depending from each of the first and second molds for relatively centering the molds.

Apparatus for molding lenses

Method for molding lenses

An improved method for manufacturing hydrophilic polymeric devices wherein surfactants are added to the hydration bath to assist in the mold release and processing of hydrophilic polymeric devices, especially hydrophilic contact lenses.

Method of using surfactants as contact lens processing aids

An improved method for manufacturing contact lenses wherein monomer or comonomer mixture is placed into a mold caivty and subjected to polymerization conditions to form a polymerized shape of desired shape wherein the improvement comprises the inclusion of a release agent in the monomeric mixture wherein said release agent comprises less than about three weight percent of said monomeric mixture and is chosen from a mixture of hydrophilic polymers with lipophilic compounds.
