System and method for treating vision refractive errors

A computer-implemented system for improving the outcome of laser vision correction treatments of living eyes, each of the eyes characterized by a value representing each of a preoperative sphere, cylinder, axis, and higher-order aberrations, comprising:

• a processor;
• a first subsystem for receiving or calculating an amount of treatment sphere and for controlling a laser vision correction device, the treatment sphere amount being derived from:
• preoperative subjective refraction data, including the sphere, cylinder, and axis values
• an amount of a secondary sphere adjustment derived from preoperative wavefront data measured using wavefront sensors or different types of aberrometers including topography devices, the waverfront data including the higher-order aberrations values,
• a calculated preoperative spherical equivalent amount based on the preoperative subjective sphere and cylinder values,
• a calculated preoperative with or against the rule astigmatism amount based on the preoperative subjective cylinder and axis values,
• a calculated preoperative oblique astigmatism amount based on the preoperative subjective cylinder and axis values,
• a calculated preoperative 4th-order spherical aberration amount based on the preoperative wavefront data, and
• a calculated 3rd order root mean square amount based on the amount of preoperative wavefront 3rd order coma and trefoil data to be corrected.
