    • An object of the present invention is to provide a practical ophthalmic lens which has an effect of effectively retaining and sustainedly releasing a drug and has form stability before and after release of the drug, wherein the ionic polymer gel having sustained drug releasability can regulate the amount of the drug included therein, depending on the efficacy of the drug used, and storing solution for a practical ophthalmic lens. The present invention relates to a drug delivery ophthalmic lens comprising a cationic group-containing drug in the inside of a copolymer consisting of a hydrophilic monomer having a hydroxyl group in its molecule, at least one member selected from specific phosphate group-containing methacrylates a monomer having a nitrogen atom in its side chain, and a monomer copolymerizable with these components, and also relates to a drug delivery ophthalmic lens comprising an anionic group-containing drug in the inside of a copolymer consisting of a hydrophilic monomer, cationic and anionic monomers, and a monomer copolymerizable with these components, wherein the copolymer contains the anionic monomer in a ratio of 30 to 90 mol % to the cationic monomer, and also relates to storing solution for a practical ophthalmic lens.
