IMPROVED OXYGEN PERMEABLE HARD AND SEMI-HARD CONTACT LENS COMPOSITIONS, METHODS AND ARTICLES OF MANUFACTURE |
摘要 |
New monomers of a polysiloxanyl alkyl esters of acrylic and methacrylic acids and its copolymerization with alkyl esters of acrylic, methacrylic acids and/or itaconate esters to produce highly permeable contact lens material. The copolymer preferably includes a cross-linking agent and hydrophilic monomer. Contact lenses manufactured from the material are easily machined and polished into hard or semi-hard contact lenses having excellent dimensional stability. |
