SURFACE WETTABLE SILICONE HYDROGEL

摘要

PROBLEM TO BE SOLVED: To provide a new silicone-containing hydrogel material suitable as a contact lens having a polysiloxane-containing prepolymer having high oxygen permeability characteristics and a sufficiently low modulus used as a hydrophilic hydrogel formulation.

SOLUTION: The new silicone-containing hydrogel material comprises an acrylic group-capped polysiloxane prepolymer polymerized with a bulk polysiloxanylalkyl (meth)acrylate monomer and at least one hydrophilic monomer.
