The present invention provides a water-soluble silicone macromer. The water-soluble silicone macromer has a general formula: E−(M.sub.1).sub.x−(M.sub.2).sub.y, wherein M.sub.1 is a repeating unit which is derived from a silicone containing monomer, M.sub.2 is a repeating unit which is derived from a first hydrophilic monomer, and E is an ethylenically unsaturated group. The amount of M.sub.1 is in a range of 30-60 wt % based on the total weight of the water-soluble silicone macromer, and the amount of M.sub.2 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.
