Clinical utility of irx3 in keratoconus

Researchers at the University of New South Wales and the Centre for Eye Health assess the repeatability of lower‐ and higher‐order aberration measurements in patients with keratoconus using the irx3 wavefront aberrometer. The findings indicate that lower‐order aberrations tended to be less repeatable, indicating that instrument variability must be considered when monitoring progression.  Total higher‐order aberration RMS and third‐order higher‐order aberrations demonstrated a strong correlation with corneal curvature.
