Abstract
Provided are an ocular surface drug-retaining agent that enables an excellent improvement in retainability of a medicament on an ocular surface and an eye drop containing the agent. An ocular surface drug-retaining agent containing a copolymer having three different kinds of constituent units at a specific ratio can express an excellent effect of retaining a medicament on an ocular surface (in particular, a corneal surface) to allow the effect or action of the drug to be sustained over a long period of time.
