Several methods for preventing, minimizing, or delaying the incidence of posterior capsule opacification are provided. A first method involves chemically activating the surface of an implantable ocular device, such as an intraocular lens or a capsular tension ring, by grafting a chemical moiety onto the surface of the device, covalently attaching a non-cytotoxic inhibitor compound to the chemical moiety to produce an inhibitor implantable ocular device, and implanting this inhibitor implantable ocular device into the capsular bag of an eye of a patient during extracapsular cataract surgery. Appropriate inhibitor compounds include RGD mimetics, RGD peptides, and flavonoids. A second method involves surface modifying the exterior surface of a capsular tension ring by covalently attaching a mitotic inhibitor, preferably a conjugate of methotrexate and a bovine serum albumin, and implanting this inhibitor tension ring into the capsular bag of an eye of a patient during extracapsular cataract surgery. A third method involves surface modifying the exterior surface of a capsular tension ring by coating or grafting the exterior surface with a charged polyethylamine and implanting this inhibitor tension ring into the capsular bag of an eye of a patient during extracapsular cataract surgery. An implantable ocular device according to the invention, such as an intraocular lens or a capsular tension ring, contains a substrate with a chemical moiety grafted thereon and a non-cytotoxic inhibitor compound covalently bonded to the chemical moiety or contains a substrate modified with a mitotic inhibitor or charged polyethylamine.
