Purpose
In this study, inter-operator reproducibility, repeatability and agreement in ocular biometry measurements between Revo NX (the new device) and IOLMaster 500 were determined.
Setting
University clinic, prospective study.
Methods
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. To test repeatability, axial length, ACD, central corneal thickness, and lens thickness were used. Two operators, A and B, also tested inter-operator reproducibility under the same conditions. The results were evaluated using Bland–Altman analyses. The differences between both methods were assessed using the paired-samples t-test, and their correlation was evaluated by intraclass correlation coefficiency (ICC).
Results
The mean ACD measured with the IOL master 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 values was 0.999 and the mean was equal to 23.47 for the new device and 23.48 for IOL master. ICC for Inter-operator repeatability was higher than 0.99 in all parameters. Revo NX showed a very high level of repeatability with ICC ranging from 0.9935 for central corneal thickness to 0.9997 for axial length.
Conclusions
Both devices showed excellent agreement and differences that are insignificant, which suggests that they can be used interchangeably.
