[Topical immunosuppressives after penetrating keratoplasty]

Topical steroids are routinely used in the postoperative treatment following penetrating keratoplasty. Due to the known side effects such as steroid-response glaucoma, cataract, and surface disorders, a broader armamentarium of topical immunomodulating drugs with comparable efficacy, better tolerance and less side effects is desirable. Cyclosporine A and FK506 eye drops are a promising alternative. A new approach involves subconjunctival drug delivering implants and locally applied antiangiogenic substances, which still have to be tested in clinical studies.
