Comparison of ocular biometry using the of a new swept-source optical coherence tomography-based optical biometer and an optical low-coherence interferometer device in patients with clear lens.

Abstract

Purpose: To compare the clinical measurements with the new IOLMaster-700 from those obtained with the Aladdin. Methods: A prospective, cross-sectional, observational Comparative study.24 eyes were assessed using the two devices. Measurements of axial length (AL), anterior chamber depth (ACD), mean keratometri (K m ) flattest (K f ), steepest keratometry (K s ) and white-to-white (WTW) were done with both devices in random order. Results: No statistically significant differences (p>0.05) between the two biometers were found for AL (mean difference 0.000 mm), ACD (mean difference 0.164 mm) and K f (mean difference 0.020 D). In K m (mean difference was 0.085 D), Ks (mean difference 0.151 D) and WTW (mean difference 0.29 mm) the differences was statistical different. Conclusions: Measurements with the new IOLMaster-700 correlated well with those obtained with the Aladdin in patients with clear lens.
