What is Comparison of 2 Swept-source Optical Coherence Tomography–based Biometry Devices about?

## Purpose: To compare 2 swept-source optical coherence tomography (ss-oct) biometers, iolmaster 700 (biometer a), and anterion (biometer b). ## Setting: Department of ophthalmology, vienna institute for research in ocular surgery, karl landsteiner institute, hanusch hospital, vienna, austria. ## Design: Retrospective study. ## Method: Biometric measurements of cataract patients performed between june and july 2019 were reviewed. patients scheduled for cataract surgery were measured with both ss-oct devices on the same day. the following biometry parameters were compared: keratometry, central corneal thickness, anterior chamber depth (acd), lens thickness (lt), and axial length (al). ## Result: In total, 389 eyes of 209 subjects were measured with both devices. the mean absolute difference between the keratometry data of the 2 devices was 0.04 ± 0.05 mm (7.80 ± 0.26 mm for biometer a and 7.82 ± 0.26 mm for biometer b; p < .0001) for the steep keratometry readings and 0.04 ± 0.04 mm (7.63 ± 0.26 mm and 7.65 ± 0.25 mm; p < .0001) for the flat keratometry readings. for acd and lt, the mean absolute difference was 0.07 ± 0.04 mm and 0.07 ± 0.04 mm. the mean absolute difference for al w
