Repeatability of ocular biometry with IOLMaster 700 in subjects with clear lens

Abstract

Purpose: The purpose of the study was to assess the reproducibility of ocular biometry using the IOLMaster-700 in a healthy population. Methods: This is a prospective, cross-sectional, observational reproducibility study. Ocular biometry was performed three times on each of 45 studied eyes. Flattest meridian (Kf) and the steepest meridian (Ks), central corneal thickness, axial length, anterior chamber depth, aqueous depth, lens thickness, and white-to-white distances were recorded. Reproducibility was evaluated using the coefficient of variation (CV), the within subject standard deviation, and the intraclass correlation coefficient (ICC). Results: There was a high reproducibility in all parameters; CV was between 0.3 and 1 %, and the ICC was higher than 0.87 in all measurements. Conclusions: IOLMaster-700 showed high reproducibility for ocular biometry.
