Abstract
PURPOSE: To compare reproducibility, level of agreement and correlation of two ultrasonic biometers and one optical biometer for the calculation of accommodative intraocular lens. METHODS: Cataract patients were submitted to the examination with 3 different biometers (IOLMaster, Axis II and Humphrey Mod. 820) before the implant of the CC 3.07 % for Axis II/contact and 3.19% for IOLMaster). All biometers presented nearly equal results of the analyzed parameters (99.01% for axial length and 94.77% for anterior chamber depth). Pearson's coefficient showed a high correlation between the biometers, regarding the axial length and anterior chamber depth measurements. CONCLUSION: The devices used in this study showed excellent reproducibility and high level of agreement and of the axial length, anterior chamber depth and keratometry measurements, making it possible to reduce errors of intraocular lens calculation and visual insatisfaction after cataract surgery.
