Repeatability and agreement of wavefront aberrations of a new hybrid topographer and aberrometer in healthy eyes

This study assessed the repeatability and agreement of the Pentacam AXL Wave vs the i-Trace.

“… Pentacam AXL Wave had repeatability with an ICC for total ocular aberrations ranging from 0.84 for HOAs to 0.92 for LOAs and for corneal from 0.76 for HOAs to 0.86 for LOAs. The Sw, TRT, and CoV of all aberrations were significantly lower (better) than those of iTrace (P < .001). …

Conclusions: The repeatability estimates for wavefront aberrations using Pentacam AXL Wave were significantly better than those using i-Trace. Both devices showed excellent correlations for total ocular aberrations.“

Impact of tear optics on the repeatability of Pentacam AXL wave and i-Trace in measuring anterior segment parameters and aberrations

The study assessed the impact of tear optics on the repeatability of the Pentacam AXL Wave compared to the i-Trace.

“… All measurements with Pentacam AXL Wave with OSI < 1 had excellent repeatability, intraclass correlation coefficient (ICC) ranging from 0.88 for HOA, to 0.92 for LOA. The Sw, TRT, and COV of all aberration measurements were significantly lower (better) than those of iTrace… .

Conclusion: Tear optics affected repeatability of Pentacam Wave and i-Trace. Pentacam Wave had better repeatability in eyes with a poor tear film as compared to i-Trace.”

Repeatability and Agreement of a New Scheimpflug Device and a Hartmann-Shack Aberrometer With a Ray-Tracing Aberrometer in Normal, Keratoconus, and CXL Groups

Besides the assessment of the device performance for normal and healthy eyes, even more interesting are their performance in abnormal - the challenging eyes. Due to the fact, that the Pentacam AXL Wave outperformed the i-Trace in the normal, healthy eye group anyway, only the repeatability of the Pentacam AXL Wave and the comparison between the two devices was analysed in the study.

METHODS: In this cross-sectional, observational study, normal, keratoconus, and CXL groups with 125 eyes in each of the three groups were included. All eyes underwent three sets of measurements, at a single visit, using the Pentacam AXL Wave (Oculus Optikgeräte GmbH) and i-Trace (Tracey Technologies). Keratometry, pachymetry, objective refraction, and total ocular aberrations including…

CONCLUSIONS: The Pentacam AXL Wave showed comparable repeatability in the normal and keratoconus groups, but was poorer in the CXL group … .
