Aberrometry from astronomy to vision science

Abstract

AAberrometry is a branch of optical metrology and more specifically of astronomy. This branch is applied to the science of vision. It allows dramatic improvements in human vision research, such as refining the visual capabilities of healthy and diseased subjects beyond physiological limits. Aberrometry relies on the ocular wave front collection with the help of an aberrometer, which allows establishing the precise and quantitative record of the various optical aberrations of the human eye, whether low or high degree.
In this work, we draw our approach to apply these concepts to refractive surgery and adaptation in order to relate the changes in Higher-Order Aberrations (HOAs) following wavefront-guided femtosecond laser-assisted (WFG FS-LASIK), and to explore the correlations between preoperative spherical equivalence (SE) and mechanisms of HOAs affecting the visual quality.
