Decentration measurements of the children treated with PRK who were cooperative enough for corneal topography. Mean decentration was 0.68 ± 0.43 mm. The one extreme outlier had a preoperative spherical equivalent refractive error of −21.00 and visual acuity of 5/200 preoperatively and postoperatively with eccentric fixation in this eye. The other outlier with decentration of more than 1 mm had had a hyperopic PRK.
