Compensatory Corneal Epithelial Thickness Changes after Myopic Photorefractive Keratectomy Imaged with Ultra High Resolution Anterior
Segment Optical Coherence Tomography
Author(s): Athina Plakitsi
Purpose: To evaluate how corneal epithelium thickness changes after myopic Photorefractive Keratectomy (PRK) relate to
the magnitude of myopic correction, the diameter of the Optical Zone (OZ) and the incidence of regression in the early
postoperative period.
Setting: Tertiary referral center
Design: Prospective longitudinal cohort study
Methods: Twenty-two eyes of 11 patients with mean manifest spherical equivalent of -4.75 ± 1.69 D underwent PRK between
November 2016 and March 2017. Epithelial thickness profiles were evaluated preoperatively and at 1, 3 and 6 month’s
postoperatively using ultra-high resolution anterior segment OCT. The relationship between post-operative epithelial thickness
changes and the magnitude of myopic correction, the OZ diameter and the re.. View More»
