Abstract (en)

[origin: WO2009001987A1] The present invention relates to a silicone hydrogel composition for a soft contact lens and a soft contact lens using the same which comprises silicone N,O-bis(trimethylsilyl)acrylamide monomer and 2-hydroxyethyl methacrylate added with water soluble N-vinyl-2-pyrrolidone or N,N-dimethylacrylamide monoer to improve hydrophilic property and a cross-linking agent such as ethylene glyx>l dimethacrylate or divinyl benzene to provide a hydrophilic property, high water content rate, high oxygen permeability, good elongation and optical transmission.
