  • Hydrogel contact lens having wet surface, and manufacturing method therefor
    Patent number: 10371965
    Abstract: The present invention relates to a hydrogel contact lens having a wet surface, and a manufacturing method therefor and, more specifically, to a hydrogel contact lens and a manufacturing method therefor wherein the hydrogel contact lens satisfies basic physical properties of a hydrogel contact lens and has excellent wettability by forming a hydrophilic surface layer of an interpenetrating polymer network (IPN) structure on a surface of the hydrogel contact lens.

  • Hydrogel contact lenses having improved wettability
    Patent number: 8530532
    Abstract: The present invention relates to a hydrogel contact lens having improved wettability, and particularly to a hydrogel contact lens of a complex membrane having an IPN (interpenetrating polymer network) intra structure, which is prepared by crosslinking composition for a contact lens comprising, as a main ingredient, an acryl monomer and an oligosaccharide and optionally a silicone compound. Due to the presence of an oligosaccharide in a contact lens herein, tensile strength and wettability can be maximized to provide a superior wearing feeling and maintain wettability even after a long-term storage in a care solution such as a washing solution, a storage solution and a protein-removing solution.
