Abstract
Refractive surgeons are familiar with the risk of ectasia after LASIK. Ectasia after PRK may be due to retreatment, unrecognized keratoconus or forme fruste keratoconus [1, 2]. Koch [3] reported the case of a patient who developed bilateral corneal ectasia after an uneventful PRK. Risk factors for the development of ectasia following excimer laser include high myopia, reduced preoperative corneal thickness, a reduced residual stromal bed after laser ablation and asymmetrical corneal steepening (forme fruste keratoconus) [4]. However, none of these characteristics definitively predict the development of ectasia. We present a case in which corneal ectasia developed 14 years after PRK with no identifiable risk factors, even when a surface ablation was performed.
