摘要： Provided is a drug sustained-releasing medical contact lens in which a component that is water-insoluble and has pharmacological activity is retained to impart drug sustained-releasability, and which is excellent in oxygen permeability. It has been found that a drug sustained-releasing medical contact lens containing a specific amount of each of a silicone-based polymer having a specific structure and a drug having a specific solubility can achieve the above-mentioned contact lens.

摘要： Provided is a treating solution for soft contact lenses capable of imparting hydrophilicity and sustainability thereof to a soft contact lens surface. It has been found that a treating solution for soft contact lenses containing a copolymer that contains two kinds of monomers different from each other as constituent units at a specific ratio, and that has a specific weight-average molecular weight can impart excellent hydrophilicity and sustainability thereof.

摘要： Provided is an ophthalmic solution for treatment or prevention of lid wiper epitheliopathy, which is capable of imparting sufficient lubricity to a corneal surface or a soft contact lens surface. It has been found that the above-mentioned object can be achieved by an ophthalmic solution containing, at a specific ratio, a copolymer having a structure having three kinds of different constituent units at a specific ratio.
