Comparison of central corneal thickness measurements with three new optical devices and a standard ultrasonic pachymeter.

摘要

AIMTo compare the RTVue spectral optical coherence tomography (SD-OCT), Sirius Scheimpflug-Placido topographer, Lenstar optical low coherence reflectometry (OLCR) and ultrasound pachymetry (USP) devices in terms of their agreement and repeatability of measuring central corneal thickness (CCT).
