Abstract

Contact lens can be used for either visual or therapeutic purposes after a successful penetrating keratoplasty. For optimal visual rehabilitation, contact lenses may be required when there is marked postoperative astigmatism, anisometropia or aphakia. On the other hand, bandage soft contact lenses are used to promote surface healing in the presence of persistent epithelial defect. Advances in microsurgical techniques and postoperative care have made it possible to achieve a high rate of clear graft in a number of clinical conditions. Despite all these advances, many corneal surfaces remain irregular and have high degrees of astigmatism following penetrating keratoplasty. Although lenses can be fitted when sutures are in place, rigid lenses are usually fitted after suture removal, 12 to 18 months postoperatively. Prior to lens fitting, K readings and manifest refraction should be stable over a period of a couple of months.
