Repeatability, reproducibility, and comparison of ocular biometry using a new optical coherence tomography-based system and another device.

ABSTRACT: Precise measurement of axial length before cataract surgery is necessary for the proper lens implantation. We included 100 eyes of 56 patients in the study. The mean age was 41 (15-84 years). Measurements of axial length, anterior chamber depth (ACD) carried out with the new Revo NX were compared with those obtained with the IOLMaster 500. Interoperator testing was performed on 56 eyes of 56 participants. To test repeatability, axial length, ACD, central corneal thickness, and lens thickness were used. Inter-operator reproducibility was also assessed. The results were evaluated using Bland-Altman analyses. The mean ACD measured with the IOLMaster and Revo NX was 3.41 and 3.40 mm p = 0.467, respectively. The interclass correlation was excellent at the level of 0.975. ICC for axial length va
