摘要： Provided are methods for determining an axis of best vision of an eye or for objectively determining a visual axis of an eye and for making the most accurate measurement of refraction. Generally, an optical measuring device or instrument projects laser beams into the eye during a scan. Positions of the projected beams are detected and measured on the retina to produce a set of projections. Wave front tilt of radiation that is backscattered from the retina is calculated as a best fit from the set of projections. The axis of best vision or the visual axis is reconstructed from a set of those traces of chief rays exiting from the eye that cross the nodal point of the optical system of the eye and that are normal to the wave front tilts. Measuring with the Styles Crawford scans centered over this axis provides the most accurate objective refraction.

摘要： Provided herein are methods for objectively determining a visual axis of an eye. An optical axis of a measuring instrument is aligned with an unambiguously determinable axis of the eye which is the pupillary axis crossing the vertex of an anterior surface of a cornea and perpendicular to the vertex. A wave front tilt of radiation of a set of narrow laser beams backscattered from the retina is calculated as a tilt component in a polynomial that describes the wave front. The visual axis is reconstructed from a set of chief rays exiting from the eye after crossing nodal points of the optical system of the eye.
