Abstract: An objective of the present invention is to provide a method for manufacturing a soft ocular lens in which the surface of the lens is hydrophilized by means of plasma processing, wherein a substrate surface can be sufficiently hydrophilized by performing, once, a reaction between the substrate and a hydrophilic polymer. Another object of the present invention is to provide a soft ocular lens with sufficient hydrophilicity which comprises only one layer comprising a hydrophilic polymer on a substrate surface. A substrate comprising a hydrocarbon group-containing polysiloxane is subjected to plasma processing with an inert gas such as nitrogen, to form a radical including Si—CH2 on the substrate surface, and produce radical rearrangement with a hydrophilic polymer, thereby causing the hydrophilic polymer to bind to the substrate surface by recombination of a radical generated in the hydrophilic polymer with the substrate.

Abstract: The purpose of the present invention is to provide a method for producing an unhydrated ophthalmic lens in which the lens surface has been made hydrophilic by imparting, using a simple technique, desired water wettability and stability against the surrounding environment to the lens surface of an unhydrated ophthalmic lens comprising a silicone compound as its constituent. This purpose can be achieved by a method for producing an unhydrated ophthalmic lens having on its lens surface a hydrophilic polymer having an alkyl halide at terminal, comprising the step of bringing an unhydrated ophthalmic lens having an alkyl halide into contact with a first aqueous solution containing a first hydrophilic monomer and a metal complex to obtain the unhydrated ophthalmic lens having on its lens surface a hydrophilic polymer having an alkyl halide at terminal.
