摘要： A silicone hydrogel composition includes a first hydrophilic monomer, a siloxane compound, a first crosslinking monomer, a second hydrophilic monomer, and a second crosslinking monomer. The first hydrophilic monomer and the siloxane compound have an acrylate group or an acrylamide group and may also have a methacrylate group or a methacrylamide group. The first crosslinking monomer has a plurality of acrylate groups or acrylamide groups and may also have methacrylate groups or methacrylamide groups. The second hydrophilic monomer has a non-conjugated vinyl group. The second crosslinking monomer has a plurality of non-conjugated vinyl groups. A sum of the weight of the second hydrophilic monomer and the weight of the second crosslinking monomer is 40 to 100 parts by weight, relative to 100 parts by weight of the sum of the weight of the first hydrophilic monomer, the weight of the siloxane compound, and the weight of the first crosslinking monomer.

摘要： The present invention provides a water-soluble silicone macromer. The water-soluble silicone macromer has a general formula: E−(M1)x−(M2)y, wherein M1 is a repeating unit which is derived from a silicone containing monomer, M2 is a repeating unit which is derived from a first hydrophilic monomer, and E is an ethylenically unsaturated group. The amount of M1 is in a range of 30-60 wt % based on the total weight of the water-soluble silicone macromer, and the amount of M2 is in a range of 40-70 wt % based on the total weight of the water-soluble silicone macromer. A silicone hydrogel composition containing the water-soluble silicone macromer and a silicone hydrogel lens made of the silicone hydrogel composition are also provided herein.
