Document Type and Number:
WIPO Patent Application WO/2017/203550
Kind Code:
A1
Abstract:
The present invention relates to a liquid preparation for soft contact lenses, more particularly hydrogel contact lenses or silicone hydrogel contact lenses. The liquid preparation according to the present invention for contact lenses comprises a hydrolyzed hyaluronic acid derivative which has a monoether of a linear or branched alkyl or alkenyl group carrying 6-20 carbon atoms, inclusive, with glycerol in a side chain. The liquid preparation according to the present invention for soft contact lenses may comprise one or more kinds of cationic bactericides selected from the group consisting of alexidine salt-based, chlorohexidine salt-based, polyhexamethylene biguanide salt-based and quaternary ammonium salt-based cationic bactericides. The liquid preparation according to the present invention for soft contact lenses can inhibit the adsorption of the cationic bactericide(s) on a soft contact lens and prevent the onset of corneal staining in a wearer.
