Abstract
A method for detecting refractive errors in the eye that are attributable to a suboptimal surface shape of the front surface and/or rear surface of the cornea. An OCT volume scan and/or one or more OCT line scans of the front eye section are carried out; using the measured values, the front and rear surface of the cornea are detected by an edge detection process; the topography of the front and rear surface of the cornea are determined; and refractive errors are determined from said topographies.
