Abstract: PROBLEM TO BE SOLVED: To provide a method for optimizing the recipe to laser-ablation corneal treatment. SOLUTION: A method for optimizing a prescription for laser-ablation corneal treatment 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. COPYRIGHT: (C)2003,JPO

Abstract: PROBLEM TO BE SOLVED: To provide a method for optimizing a prescription for a laser ablation type cornea treatment or an ophthalmologic implantation. SOLUTION: The method is an actually measured correction prescription for a present patient having a related classification element, and contains a step receiving the actually measured correction prescription using a wavefront type determination method. It is a data base of a treatment result on a plurality of previously treated patients. Each of the patient treatment results has at least one related classification element, and the database provided with the wavefront determination type correction prescription before the treatment and a visual profile after the treatment is accessed. From the treatment result in the database, the average difference between the pre-treatment prescription and the post-treatment visual profile in at least some previously treated patients having the classification element common to the present patient is calculated. In the last, the present correction prescription for the patient is adjusted so as to correspond to the calculated average difference, and an optimum prescription is formed. COPYRIGHT: (C)2003,JPO

Abstract: A system (10) and method for converting measured wavefront data into an ablation profile for correcting visual defects includes providing measured wavefront (24) data on an aberrated eye by a method such as known in the art. The measured wavefront data (701) are correlated with accumulated data on previously treated eyes. Next an adjustment is applied to the measured wavefront data based upon the correlating step (707). This adjustment is used to form adjusted wavefront data (708) for input to a wavefront data correction algorithm to calculate an ablation profile (709) therefrom. The wavefront data correction algorithm may be modeled as, for example, Zemike polynomials with adjusted coefficients.

Abstract: A system for determining an accommodative force in a patient includes a sensor adapted to detect motion of a lens of the patient relative to a globe of the patient's eye, a controller configured to determine an accommodative force in the patient based on the relative motion and to determine at least one parameter for an intraocular lens based on the accommodative force, and an interface adapted to output the at least one parameter for the intraocular lens.

Abstract: A method for optimizing a prescription for an 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, which is then transmitted automatically to an implant manufacturing device.
