Comparison of two novel swept-source optical coherence tomography devices to a partial coherence interferometry-based biometer

Abstract To evaluate the repeatability and agreement of corneal biometry measurements obtained with two swept-source optical coherence tomography (SSOCT) a partial interferometry-based device. This is cross-sectional study. Forty-eight eyes 48 patients had three consecutive for ANTERION (Heidelberg Engineering, Germany), CASIAII (Tomey, Japan) IOLMaster500 (Carl Zeiss Meditec, USA) on same visit. Mean keratometry (Km), central thickness (CCT), anterior chamber depth (ACD) axial length (AL) were recorded. Corneal astigmatic converted into vector components—J0 J45. Intra-device agreements amongst devices evaluated using coefficients (RCs) Bland–Altman plots, respectively. All demonstrated comparable Km (p ≥ 0.138). lowest RC J0 ≤ 0.039). Systematic difference was found compared to either SSOCTs 0.010). The ACD AL measured by showed higher < 0.002). in CCT between 0.001), mean 1.6 µm, 0.022 mm 0.021 mm, Both smaller test–retest variability measuring IOLMaster500. There significant disagreement PCI-based device; their should not be considered as interchangeable.
