Abstract

PURPOSE

To report a case of severe corneal scarring and hyperopic shift after corneal cross-linking (CXL) for the treatment of ectasia following small incision lenticule extraction (SMILE).

METHODS

Case report and literature review.

RESULTS

A 35-year-old man was referred with severe unilateral corneal haze that developed after CXL. The patient had undergone SMILE 4 years earlier in both eyes. Nineteen months postoperatively, the patient presented with bilateral decrease in vision and corneal topography revealed corneal ectasia in the right eye. CXL was performed in the right eye and a deep stromal haze was observed 1 year later. Comparative maps showed progressive corneal thinning with corresponding flattening that induced hypermetropization and astigmatism.

CONCLUSIONS

CXL after SMILE in this original case resulted in severe deep corneal haze and corneal flattening with hyperopic shift. [J Refract Surg. 2018;34(11):779-782.].
