Abstract: Des réactions biomécaniques de l'oeil sont utilisées en vue d'améliorer les procédures photoréfractives. Les traitements LASIK ou PRK, par exemple, peuvent être améliorés en prenant des mesures pré-opératoires et en prévoyant la réaction biodynamique de la cornée au traitement ablatif. L'utilisation prévisionnelle découle de la réaction biodynamique de la cornée au laser ou à la kératectomie mécanique, à savoir, de la création d'une caractéristique du lambeau cornéen du LASIK. La comparaison entre le lambeau avant et après, les données (de pré-ablation) de la cornée telles que l'épaisseur de la cornée, l'épaisseur du lambeau, la topographie de la cornée et le front d'ondes, par exemple, peuvent fournir des informations prévisionnelles applicables en vue de modifier l'algorithme d'ablation avant d'utiliser le laser, soit pour une opération réel soit pour le développement d'un modèle. La modélisation, par analyse d'élément fini ou d'autres techniques mathématiques, peut également être utilisée en vue de prévoir les résultats post-opératoires fondés sur les données pré-opératoires (pas de coupe de lambeau ou autre intervention chirurgicale) de la cornée lesquels sont entrées pour un modèle d'oeil précis qui, en prenant en considération la réaction biodynamique <i>via</i> le modèle, fournit des informations prédictionnelles destinées à améliorer le succès de la chirurgie réfractive et par là même la satisfaction du patient.
