Abstract

The present invention provides an ophthalmic composition which stabilizes the tear film during wearing contact lens, prevents eye dryness, imparts a favorable sensation in using, is highly convenient with no risk of misuse and shows a high efficiency in the course from manufacturing to sales. More specifically, the present invention provides a wetting solution—eye drops for contact lenses comprising (A) one or more member (s) selected from the group consisting of a cellulose-based polymer, a vinyl-based polymer, polyethylene glycol and dextran; and (B) a terpenoid.

Claims

exact text as granted — not AI-modified
1 . A wetting solution—eye drops for contact lenses comprising (A) one or more member(s) selected from the group consisting of a cellulose-based polymer, a vinyl-based polymer, polyethylene glycol and dextran; and (B) a terpenoid. 
     
     
         2 . The wetting solution—eye drops for contact lenses according to  claim 1 , wherein the component (A) is a cellulose-based polymer. 
     
     
         3 . The wetting solution—eye drops for contact lenses according to  claim 2 , wherein the cellulose-based polymer is one or more member(s) selected from the group consisting of hydroxyethyl cellulose, hydroxypropylmethyl cellulose, and salts thereof. 
     
     
         4 . The wetting solution—eye drops for contact lenses according to any one of  claims 1  to  3 , which comprises the component (A) in an amount of 0.0001 to 25 (w/v) %. 
     
     
         5 . The wetting solution—eye drops for contact lenses according to  claim 1 , wherein the terpenoid is menthol. 
     
     
         6 . The wetting solution—eye drops for contact lenses according to  claim 1 , which comprises the component (B) in an amount of 0.0001 to 0.1 (w/v) %. 
     
     
         7 . The wetting solution—eye drops for contact lenses according to  claim 1 , which further comprises (C) a nonionic surfactant. 
     
     
         8 . The wetting solution—eye drops for contact lenses according to  claim 7 , wherein the component (C) is one or more member(s) selected from the group consisting of polyoxyethylene sorbitan fatty acid esters, polyoxyethylene hydrogenated castor oil and polyoxyethylene-polyoxypropylene copolymer. 
     
     
         9 . The wetting solution—eye drops for contact lenses according to  claim 7  or  8 , wherein the component (C) is polysorbate 80. 
     
     
         10 . The wetting solution—eye drops for contact lenses according to  claim 7 , which comprises the component (C) in an amount of 0.001 to 5 (w/v) %. 
     
     
         11 . The wetting solution—eye drops for contact lenses according to  claim 1 , wherein the contact lens is a soft contact lens. 
     
     
         12 . The wetting solution—eye drops for contact lenses according to  claim 11 , wherein the soft contact lens is essentially in soft contact lens Group IV. 
     
     
         13 . The wetting solution—eye drops for contact lenses according to  claim 11 , wherein the soft contact lens is a soft contact lens made of silicone-hydrogel. 
     
     
         14 . The wetting solution—eye drops for contact lenses according to  claim 1 , for suppressing eye desiccation or dry eye.
