Abstract
Particular embodiments disclosed herein provide an apparatus for performing optometric measurements includes an optical coherence tomography (OCT) imaging system configured to output scanned parallel laser beams across a patient's eye. A line in the OCT image is identified, the line representing a retina of the patient's eye. A shape of the line is then used by the refractive error calculator to measure refractive error of the patient's eye. The height of the line due to curvature indicates degree of myopia or hyperopia. More complex curvature of the line corresponds to higher order aberrations. OCT images for a plurality of section planes may be used to calculate a wavefront elevation map.
