Abstract
A method for optimizing a prescription for laser-ablation corneal treatment includes receiving a measured correction prescription for a current patient. Next a database of treatment outcomes on a plurality of previously treated patients is accessed. The database contains a desired correction, and an actual correction. A difference between the desired correction and the actual correction represents an over- or undercorrection resulting from surgery. From the difference data is calculated a distribution of data points as a function of correction level. From the data-point distribution is calculated a statistically based offset applicable to the correction prescription for matching actual corrections with desired corrections. From the data-point distribution is calculated a confidence interval of the data using a predetermined confidence level. The statistically based offset is then adjusted based upon the confidence interval to provide an optimized prescription. The adjusted offset is then output for use in performing a refractive procedure.
