Abstract
Aberrometry is a branch from optical metrology and more directly from astronomy. Applied to the science of vision, it allows for dramatic improvements in human vision research, such as refining the visual capabilities of healthy and diseased subjects beyond physiological limits. In retinal imaging, it permits observing with very high resolution, photoreceptors allowing glimpsing an earlier diagnosis of some retinal pathologies as well as the observation and assessment of more effective treatments. They rely 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 contact lenses adaptation, 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.
