Abstract:
Provided is a tear lipid layer stabilizer that is capable of stabilizing a tear lipid layer and allowing the tear lipid layer to sufficiently spread over a corneal surface, to thereby prevent the evaporation of a tear aqueous layer on the corneal surface, and hence is suitable for amelioration, alleviation, or treatment of evaporative dry eye symptoms caused by Meibomian gland dysfunction, an ophthalmic solution having blended therein the tear lipid layer stabilizer, and a tear lipid layer-stabilizing method using the tear lipid layer stabilizer. The tear lipid layer stabilizer includes a copolymer that has a weight-average molecular weight of from 10,000 to 5,000,000, and contains 10 mol % to 90 mol % of a constituent unit (A) based on 2-(meth)acryloyloxyethyl phosphorylcholine and 90 mol % to 10 mol % of a constituent unit (B) based on an alkyl group-containing (meth)acrylic monomer.

Claim (Index 20):
A tear lipid layer-stabilizing method according to  claim 19 , wherein the constituent unit (A) comprises a constituent unit based on 2-methacryloyloxyethyl phosphorylcholine, and the constituent unit (B) comprises a constituent unit based on butyl methacrylate.
