Corneal ectasia after LASIK in a patient with normal scheimpflug evaluation but a high Ectasia Risk Score
Purpose:
To present a case of ectasia after LASIK that developed in a patient with normal Scheimpflug imaging but a high Ectasia Risk Score System (ERSS) score.
Methods:
Case report.
Results:
A 24-year-old woman with no preoperative abnormalities on Scheimpflug evaluation but a cumulative ERSS risk of 4 (high risk) in the right eye and 3 (medium risk) in the left eye developed ectasia in both eyes 27 months after LASIK. She underwent ultraviolet-A corneal collagen cross-linking, with no signs of further progression.
Conclusions:
In this case, the ERSS was effective at predicting ectasia risk despite normal Scheimpflug imaging and only mild asymmetry on Placido topography.
