Comparison of ocular biometric measurements between a new swept-source optical coherence tomography and a common optical low coherence reflectometry

Abstract The purpose of the current study was to compare the measurements between a new optical biometer based on swept-source optical coherence tomography (SS-OCT), the OA-2000 (Tomey, Japan), and an optical biometer based on optical low coherence reflectometry (OLCR), the Lenstar (Haag-Streit, Swi...
