Abstract
A method for optimizing a prescription for laser-ablation corneal treatment or ophthalmic implant includes the steps of receiving a measured correction prescription for a current patient having a classification element associated therewith, the prescription having been measured using wavefront determination. A database of treatment outcomes on a plurality of previously treated patients is accessed, each treated patient outcome having associated therewith at least one classification element and comprising a preoperative wavefront-determined correction prescription and a postoperative visual profile. From the treatment outcomes in the database is calculated an average difference between the preoperative prescription and the postoperative profile for at least some of the previously treated patients having a classification element in common with the current patient. Finally the current patient correction prescription is adjusted commensurate with the calculated average difference to form an optimized prescription.
