Besides routine postoperative follow-up the prophylaxis of complications in penetrating keratoplasty (PKP) includes special preoperative and intraoperative aspects. Preoperative prophylaxis consists of the therapy of systemic diseases and eyelid abnormalities, determining individual optimal graft size, avoiding PKP in cases of uncontrolled intraocular pressure, avoiding PKP in cases of corneal hydrops, pretreatment of vascularized cornea, amniotic membrane transplantation before PKP in cases of ulcerative keratitis, quality controlled organ-cultured transplants and preoperative counselling by the surgeon to ensure patient compliance. Intraoperative prophylaxis consists of controlled arterial hypotension and complete relaxation during general anesthesia, avoidance of decentration, horizontal torsion and vertical tilt using a non-contact trephination technique (preferably excimer laser) with double-running cross-stitch sutures and application of Flieringa rings in aphakic vitrectomized eyes. Postoperatively, periodical control examinations using fluorescein and blue light are indispensable. All loose sutures have to be removed as early as possible. In cases of herpetic eye disease 2 × 400 mg of oral acyclovir should be administered for at least 1 year. In cases of therapy-resistant epithelial defects 100 % autologous serum eyedrops or amniotic membrane patches are valid options. Immune reactions must be diagnosed and treated immediately with high doses of corticosteroids.
