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.

Abstract: Procedimiento (100) para crear un sistema destinado a optimizar una receta para una corrección de la refracción, que comprende las etapas siguientes: a) formar una base de datos (14) de resultados del tratamiento en un conjunto de pacientes tratados, teniendo asociado por lo menos un elemento de clasificación y comprendiendo una receta de la corrección determinada por el frente de onda (11) preoperatorio y un perfil visual posoperatorio; b) proporcionar un programa de búsqueda (16) que comunica con un procesador (12) adaptado para extraer resultados del tratamiento basados en un elemento de clasificación; c) proporcionar un primer módulo informático (13) para su utilización por el procesador, estando adaptado el primer módulo informático para calcular (104) a partir de los resultados extraídos del tratamiento en la base de datos una diferencia media entre la receta preoperatoria y el perfil posoperatorio de por lo menos alguno de los pacientes tratados anteriormente que tienen un elemento de clasificación en común con el paciente presente; d) proporcionar un segundo módulo informático (13) para su utilización por el procesador, estando adaptado el segundo módulo informático para ajustar la receta de la corrección del paciente presente en proporción a la diferencia media calculada para formar (108) una receta optimizada, teniendo el paciente presente un elemento de clasificación asociado y habiendo presentado un determinación del frente de onda realizada para medir una receta de corrección inicial, y e) proporcionar unos medios para transmitir (118) la receta optimizada automáticamente a un dispositivo de fabricación del implante (15). - - - (En el mencionado fascículo siguen las versiones en alemán y en francés, respectiva-mente, de las mismas reivindicaciones que se han traducido de la versión en inglés). - - - - 3 - - 7 - 1
