Corneal ectasia after photorefractive keratectomy for low myopia.
OBJECTIVE
To alert ophthalmologists of the possibility of an aggravation of forme fruste keratoconus after photorefractive keratectomy (PRK).


METHODS
Clinical case report.


METHODS
Standard bilateral PRK for low myopia.


METHODS
Corneal topography, corneal thickness, and visual acuity.


RESULTS
Corneal ectasia occurred bilaterally after PRK. Retrospective analysis of preoperative videokeratography indicated the existence of forme fruste keratoconus on the left eye.


CONCLUSIONS
This article is the first case report of a bilateral corneal ectasia after PRK for low myopia. Even if there is no direct proof to demonstrate that PRK has worsened the evolution of keratoconus, the safety of the PRK procedure in forme fruste keratoconus must be considered.
