  • METHOD FOR INDUCING GREATER WETTABILITY OF CONTACT LENS COMPOSITIONS DURING MOLDING
    Publication number: 20230159733
    Abstract: A method for producing a contact lens having a water contact angle below about 90° involves preparing a molding resin comprising a polyether modified polyolefin; forming the molding resin into a mold; preparing a contact lens composition; filling the contact lens composition into the mold; and polymerizing the contact lens composition to form a contact lens. A method of inducing water contact angle below 90° and improved surface wettability of a contact lens involves cast polymerizing a mixture of monomers in a mold formed from a molding resin containing a polyether modified polyolefin to form a contact lens having a water contact angle of less than about 90°. Single-use molds for contact lens manufacture are also provided.
