Piñero DP, et al. - In this study enrolling 35 healthy eyes of 35 patients (age, 16–66 years), researchers assessed the intrasession repeatability of anterior corneal topographic and aberrometric measurements afforded by a color-LED topographer as well as their interchangeability with those offered by a Scheimpflug-based system. All participants underwent complete eye testing including a complete corneal examination with the Scheimpflug-based system Pentacam (Oculus Optikgeräte) (one measurement) and the Cassini system (i-Optics) (three consecutive measurements). With the within-subject standard deviation and the intraclass correlation coefficient, the evaluation of intrasession repeatability of the Cassini measurements was done. Findings revealed that color-LED topography provided consistent anterior corneal topographic, total corneal astigmatic, and aberrometric measurements in healthy eyes, which were not interchangeable with those offered by the Scheimpflug-based topography.
