Abstract Details

Purpose:

To alert ophthalmologists of the possibility of iatrogenic corneal ectasia following PRK in cases with thin cornea in otherwise normal topography.

Setting:

Cornea and Refractive surgery Unit, Magrabi eye ceneter, Jeddah ,Saudi Arabia

Methods:

Clinical case report of bilateral standard PRK for low myopia, with retrospective analysis of corneal topography, visual acuity and corneal thickness.

Results:

Retrospective analysis of the records showed that manifest refraction was (-2.25 -1.0 X 85) in right eye and (-2.0 -1.25 X 100) in left eye. Central corneal thickness was 462 and 460 ┬Ám OD and OS respectively. Central simulated keratometry was 42.99/42.45 D in right eye and 43.38/42.40 D in left eye. Preoperative corneal topography obtained with OPD-scan II (NIDEK Co., Ltd.) was within normal apart from mild axis skewing in one eye and was classified as normal based on the Placido topography analysis by the OPD-scan II Corneal Navigator neural-network software (NIDEK). Corneal ectasia occurred bilaterally after PRK.

Conclusions:

Corneal ectasia after PRK for low myopia may develop in patients with normal placido topography. Even if there is no direct proof to demonstrate whether thin cornea was the risk factor responsible for the evolution of iatrogenic ectasia, the safety of the PRK procedure in patient with thin cornea must be a concern.
