Resumen
Purpose
To evaluate the agreement between preoperative optical coherence tomography (OCT)-derived central corneal epithelial thickness (CET) and an intraoperative epithelial thickness estimate derived from optical coherence pachymetry (OCP) during alcohol-assisted photorefractive keratectomy (PRK).
Methods
A retrospective analysis was performed on 116 eyes of 58 consecutive patients who underwent bilateral myopic alcohol-assisted PRK between June 2020 and October 2021. Preoperative CET was assessed using anterior-segment OCT. The OCP-derived intraoperative epithelial thickness estimate was calculated as the difference between total corneal pachymetry readings obtained immediately before and after epithelial removal. Demographic, preoperative clinical, and refractive data, as well as intraoperative laser parameters, were collected.
