Wavefront fusion algorithms for refractive vision correction and vision diagnosis

摘要

Accommodation-Free Wavefront, wave aberration of an eye at the far accommodation points, is determined using a wavefront fusion algorithm by obtaining a wave aberration of an eye from a wavefront measurement, obtaining a manifest refraction of an eye at a far accommodation point according to a conventional subjective refraction, and determining a wave aberration of the eye at its far accommodation point based on a combination of the manifest refraction and the measured wave aberration of the same eye. Wave aberration of an eye at the far accommodation points enable accommodation-free wavefront-guided vision corrections as well as comprehensive vision diagnosis of human vision based on a true-vision wavefront. True-Vision wavefront is determined from the accommodation-free wavefront with removal of a refractive prescription of a correction lens if the lens is used for a sphero-cylindrical correction.
