N2 - Purpose: To compare anterior eye segment measurements obtained using low optical coherence reflectometry (LENSTAR LS900, Haag-Streit), autokeratometry (RC-5000, Tomey) and corneal topography (Topolyzer, Wavelight). Methods: In 46 healthy subjects, flat keratometry (Kf), steep keratometry (Ks), mean keratometry (Km) and white-to-white (WTW) distance were measured by Lenstar, Tomey RC-5000 and Topolyzer. Results: Kf and Km measurements of Lenstar were significantly steeper than Tomey RC-5000 (both pf and Km measurements of Lenstar and Topolyzer, with a narrow 95% LoA. There were no significant differences between the Ks measurements of Lenstar and Tomey RC-5000, and Lenstar and Topolyzer. A good agreement was found between them with 95% LoA of -0.40 to 0.56D, and -0.56 to 0.64D, respectively. WTW measurements with Lenstar were greater than those with Tomey RC-5000 and Topolyzer (p=0.042, p
