الملخص EN

Purpose : To report a case of bilateral corneal ectasia fifteen years post photorefractive keratectomy (PRK) in one eye and laser in-situ keratomileusis (LASIK) in the fellow eye.

Case : A 35-year-old-female with no previous illnesses and a presumably normal topographic pattern underwent PRK in her right eye and LASIK in the more myopic left eye.

A retrospective analysis of the topography pattern with the current medical knowledge revealed the possibility of a form fruste keratoconus in the left eye.

After yearly normal examinations, and despite the differences in risk factors and the technique used, the patient developed a bilateral corneal ectasia fifteen years later.

Conclusion : Long-term follow-up is essential for the assessment of the safety of different types of keratorefractive surgeries in all patients regardless of their preoperative risk factors.
