Central Corneal Thickness Measurements With Fourier-Domain Optical Coherence Tomography Versus Ultrasonic Pachymetry and Rotating Scheimpflug Camera

Abstract

RTVue-100 FD-OCT may be a useful alternative for measuring the CCT; however, it significantly underestimates the CCT compared with the USP and the Pentacam with slight differences. Although highly correlated, the measurements are not directly interchangeable in clinical practice.
