Determining clinical refraction of eye

摘要: A method of measuring eye refraction to achieve desired quality according a selected vision characteristics comprising the steps selecting characteristic correlate from group acuity, Strehl ratio, contrast sensitivity, night vision, day and depth focus. dynamic over period time during focus accommodation, pupil constriction dilation; using wavefront aberration measurements objectively measure state that defines characteristic; expressing measured with mathematical function enable correction pre-selected vision. The expression may be Zernike polynomial having both second order higher terms or determined by spline calculations. ray tracing technology.
