Silicone-containing contact lens polymers, oxygen permeable contact lenses and methods for making these lenses and treating patients with visual impairment

摘要: The present invention relates to novel copolymers and contact lenses made from these comprising preformed silicon-containing acrylic star polymers macromonomers, preparation of a therapeutic method for treating patients with visual impairment. Described is copolymer at least about 10% by weight silicone-containing no more than 90% matrix formed the random polymerization mixture monomers. monomers comprises one monomer selected group consisting silicone acrylates, esters alpha, beta-unsaturated acids wetting preferably copolymerized throughout matrix. readily machined into gas permeable exhibiting substantially enhanced characteristics characteristic oxygen permeability, hardness machineability relative
