Provided is a surface treatment agent for an ophthalmic device that can impart wettability and lubricity to the surface of a silicone hydrogel, more specifically, a surface treatment agent for an ophthalmic device that can subject the silicone hydrogel to surface treatment even when the silicone hydrogel is not caused to present any specific complementary functional group. Also provided are a surface-treated silicone hydrogel whose surface has been treated with the surface treatment agent for an ophthalmic device, and an ophthalmic device using the surface-treated silicone hydrogel. It has been found that the above-mentioned objects can be achieved by using a water-soluble copolymer obtained by copolymerizing a phosphorylcholine group-containing monomer, a specific silicone monomer, and a thermally reactive monomer or a photoreactive monomer, the copolymer having water solubility controlled to a specific level. Thus, the present invention has been completed.
