Abstract

In accordance with some embodiments, a method of eye examination includes acquiring OCT data with a scan pattern centered on an eye cornea that includes n radial scans repeated r times, c circular scans repeated r times, and n* raster scans where the scan pattern is repeated m times, where each scan includes a A-scans, and where n is an integer that is 0 or greater, r is an integer that is 1 or greater, c is an integer that is 0 or greater, n* is an integer that is 0 or greater, m is an integer that is 1 or greater, and a is an integer greater than 1, the values of n, r, c, n*, and m being chosen to provide OCT data for a target measurement, and processing the OCT data to obtain the target measurement.
