Precision and agreement of higher order aberrations measured with ray tracing and Hartmann-Shack aberrometers

Abstract Background To assess the precision and agreement of measurements of higher order aberrations (HOAs) obtained with a ray tracing aberrometer (iTrace) and a Hartmann-Shack aberrometer (Topcon KR-1 W). Methods Prospective evaluation of the diagnostic test. Data from the right eyes of 92 normal...
