In some cases of centrally located corneal opacifications an optical sector iridectomy can not lead to a clear optical axis. The homologous penetrating keratoplasty as early surgical procedure has shown an extremely poor outcome with a high risk of irreversible graft failure. We report on the autologous ipsilateral rotating penetrating keratoplasty in an eight- week- old infant suffering from Peters anomaly. Patients: An autologous ipsilateral rotating penetrating keratoplasty was performed in an eight- week- old infant suffering from Peters anomaly to prevent irreversible amblyopia. Results: After a follow- up time of 8 months we saw a clear graft within the optical axis without any complications in wound healing. We removed the single sutures two months after keratoplasty. Postoperative astigmatism could be corrected first by fitting a special nursery contact lens and after reduction of astigmatismbecause of suture removalwe fitted special nursery glasses. The intraocular pressure remained within the normal range during the follow- up period. Conclusion: The autologous ipsilateral rotating penetrating keratoplasty should be considered superior to homologous keratoplasty in infants withPeters anomaly if sector iridectomy is not advisable because of a central corneal opacification. Resulting high refractive errors can be successfully corrected by special contact lens fitting or by nursery glasses.展开更多

Usually penetrating keratoplasty is the treatment of choice t o achieve an optical rehabilitation in such cases. Patients and Methods: We repo rt on a female patient who developed keratectasia in both eyes 4 weeks after LAS IK. Due to a severe keratectasia 10 months after LASIK, a treatment with ribofla vin/UVA cross-linking was performed. Results: Due to the induced collagen cross linking the biomechanical status of the cornea was stabilized and a progression of the keratectasia was prevented. The postoperative refraction and corneal topo graphy have been stable for 18 months. Conclusion: Collagen cross-linking leads to a stiffening of the anterior parts of the corneal stroma. The increase of bi omechanical stability can stop the progression of a keratectasia after LASIK by means of a simple procedure.展开更多
