Compositions and methods for the treatment of ophthalmic disorders, particularly preservation of corneal explants and prevention of corneal allograft rejection. In part, this application is based on the recognition that certain molecules that target abasic lesions or AP sites in DNA improve, augment, or potentiate the chemotherapeutic efficacy of certain anticancer agents. Transverse cross-sections of coil spring wire reveal non-uniform distributions of residual compressive stress that exhibit substantial symmetry about various transverse axes, including axes connecting potential or actual opposing coil binding contact points on the spring wire surface. Image data is read out in accordance with an address generated by the address generator, to form an image in which the curvature of a scanning line is corrected.
