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
