Abstract:
1. A method for optimizing a refractive prescription without using subjective refractions, the method comprising the steps of: a. obtaining aberrometric data from a patient by way of an aberrometer; and b. selecting an objective image quality metric, wherein the objective metric of image quality is selected from a group consisting of average blur strength (“B c. computing the objective image quality metric from the aberrometric data; d. iteratively modifying the level of spherical and cylindrical defocus of the abberometric data; e. computing the modified objective image quality metric from the modified abberometric data; f. repeating steps c and d until the modified objective image quality metric is optimized; and g. generating at least one clinical refractive sphereocylindrical prescription for the patient based on the optimized objective image quality metric.
