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 … .
