ABSTRACT
PURPOSE: To evaluate the level of agreement between ANTERION (Heidelberg Engineering, Heidelberg, Germany), OA-2000 (Tomey, Nagoya, Japan), and IOL Master 500 (Carl Zeiss Meditec AG, Jena, Germany).
METHODS: Fifty-one eyes of 51 patients were included in the study. Flat and steep keratometry (K), vector component of astigmatism (J0 and J45), anterior chamber depth (ACD), and axial length (AL) were compared using the three devices. Repeated-measures analysis of variance was conducted to compare the mean values of the biometrics. Pearson’s correlation test was conducted to analyze the correlations of the measured values, and a Bland-Altman plot was used to assess the agreement between the three devices. The predicted intraocular lens (IOL) power of each device was compared to the others using the SRK/T, Haigis, Barrett Universal II, and Kane formulas.
RESULTS: All K values measured using ANTERION were flatter than those of other instruments. However, good agreement was observed for flat K (ANTERION-OA-2000) (95% limits of agreement [LoA] = 0.86D) and steep K (ANTERION-OA-2000 [95% LoA = 0.93D]) and OA-2000-IOL Master 500 [95% LoA = 0.93D]). J0 and J45 vector components of astigmatism were not statistically different; however, the agreements were poor between the devices (95% LoA ≥ 1.97D). ACD values of ANTERION and OA-2000 were interchangeable (95% LoA = 0.15 mm). The AL showed a high agreement (95% LoA ≤ 0.17 mm) among the three devices. The predicted IOL powers of the three devices were not interchangeable regardless of formulas (95% LoA≥ 1.04D).
CONCLUSION: Significant differences in ocular biometrics were observed between ANTERION and the other two devices. This study demonstrated that only AL showed good agreement among devices.
