Patent ID: 7789513

Claim:
A method for improving an accuracy of a prescription for laser-ablation corneal treatment comprising the steps of: receiving a set of raw data comprising Hartmann-Shack image data obtained from a plurality of aberrometer measurements of a patient eye; receiving a set of reconstructed wavefront data calculated from the set of raw data for the plurality of aberrometer measurements; comparing data on a selected component of the set of raw data and in the set of reconstructed wavefront data; if the selected component data differ more than a predetermined amount between the raw data and the reconstructed wavefront data, further manipulating the raw data prior to undertaking laser ablation; receiving a diopter prescription calculated from the raw data for each of the plurality of aberrometer measurements, the reconstructed wavefront data including the diopter prescriptions, wherein the selected component data comprise the diopter prescriptions; and if a deviation between the diopter prescriptions is greater than a predetermined amount, receiving new sets of raw data and reconstructed wavefront data collected with additional aberrometer measurements.
