Publication number: 20240288711Abstract: 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.Type: ApplicationFiled: March 28, 2022Publication date: August 29, 2024Applicants: NATIONAL INSTITUTE FOR MATERIALS SCIENCE, SEED CO., LTD.Inventors: Izumi ICHINOSE, Kunio JONIN, Risako YAMANAKA
