Patent ID: 8092724

Claim:
A method for producing a contact lens, comprising: the steps of: (1) providing a contact lens mold, (2) applying to at least a part of a surface of the mold a layer of PEG-ylated phosphatidyl ethanolamines, (3) at least partially drying said layer, (4) introducing a fluid composition into a mold for making a contact lens, wherein the fluid composition comprises a lens-forming material, wherein the lens-forming material is crosslinkable and/or polymerizable by actinic radiation; (5) crosslinking/polymerizing the lens-forming material in the mold to form a lens having a polymer matrix; and (6) separating the mold, wherein the phospholipid or derivatives thereof is present in an amount sufficient to reduce an averaged mold separation force by at least about 40% in comparison with that without the phospholipid or derivatives.
