Abstract Details

Purpose:

To investigate the difference between two swept-source optical coherence tomography biometers (ss-OCT), IOLMaster 700 (biometer A, Carl Zeiss Meditec AG, Jena, Germany) and ANTERION (biometer B, Heidelberg Engineering GmbH, Heidelberg, Germany).

Setting:

Vienna Institute for Research in Ocular Surgery (VIROS), Hanusch Hospital, Vienna, Austria

Methods:

Two-hundred and ten cataract patients were measured with both biometry devices. The analysis contained the following parameters: corneal radii (CR), central corneal thickness (CCT), anterior chamber depth (ACD), lens thickness (LT), and axial length (AL).

Results:

The mean AL values were 23.55 ± 1.22 mm for biometer A versus 23.54 ± 1.22 mm for biometer B, with a difference of 0.01 ± 0.03 mm, p=0.0001. The difference between the steep keratometry data was -0.02 ± 0.07 mm, with values of 7.79 ± 0.26 mm for biometer A versus 7.82 ± 0.26 mm for biometer B, and -0.02 ± 0.05 mm, with 7.62 ± 0.26 mm versus 7.65 ± 0.25 mm for the flat keratometry, (p=0.0001). For ACD and LT the mean difference was -0.07 ± 0.05 mm and -0.06 ± 0.06 mm, p=0.0001.

Conclusions:

Comparison between the two devices revealed a good agreement, with small differences that were statistically significant, but did not appear to be clinically relevant.
