Variability in Corneal and Epithelial Pachymetry: A Comparison of Optopol Revo 130 and Optovue RTV XR Avanti in Healthy Patients.

ABSTRACT: Background/Objectives: The accurate measurement of corneal epithelial thickness (CET) and pachymetry is essential for diagnosing and managing corneal conditions such as keratoconus and for optimizing outcomes in refractive surgery. This study aimed to evaluate the agreement and repeatability of measurements between two anterior segment optical coherence tomography (AS-OCT) devices-OCT REVO FC 130 and Optovue RTV XR Avanti-in healthy individuals. Methods: This prospective, cross-sectional, observational study included 53 healthy participants. High-quality scans were performed using both devices by two trained operators. Agreement between devices was assessed using Bland-Altman analysis and Deming regression, while repeatability and reproducibility were evaluated through intrac
