Abstract

Purpose: To report the repeatability, level of agreement, and correlation of 2 swept-source optical coherence tomography (SS-OCT) biometers, the IOLMaster 700 (biometer A) and the ANTERION (biometer B).

Setting: Rothschild Foundation Hospital, Paris, France.

Design: Prospective comparative case series.

Methods: Consecutive patients who attended for cataract assessment had SS-OCT biometry performed with the reference, biometer A, and biometer B. Axial length, mean keratometry, central corneal thickness, anterior chamber depth, lens thickness, and corneal diameter measurements (white-to-white [WTW] distance) were measured. The intraoperator repeatability was calculated using analysis of variance and repeatability limits. Correlations were assessed, and the level of agreement between the biometers was represented with the Bland-Altman method.

Results: The study comprised 63 patients (125 eyes). There was a statistically significant difference between the 2 biometers in all measurements (P < .05). All repeatability measurements were very high, as were the level of correlation and level of agreement between biometer A and biometer B for all parameters.

Conclusions: Biometer B provided good agreement and repeatability compared with biometer A; however, all parameters were not interchangeable, particularly, the WTW measurement and the high keratometric values.
