Abstract: 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.

Abstract: A fixture and method is provided for in vitro storage of a cornea. The fixture includes a platform having a corneal-sceral rim receiving surface, a clamp having a mating surface for the cornel-scleral rim and handles. A locking mechanism is provided to secure a donor cornea between the clamp and platform. The combination cornea, platform and clamp are placed in a storage unit having a fluid preservation media. In one embodiment, the storage unit includes a vial having an optically clear closed end and an opened end. A lid is secured to the open end of the vial and engages the handles in order to stabilize the clamped cornea within the vial.
