Patent

CA 2515970

The present invention relates to a process in which the visual effect of different higher order aberrations is normalised in relation to the visual effect produced by defocus. In addition, it relates to a correcting factor that will normalise RMS, a test chart for measuring the effects of higher order aberrations, methods of testing for the effects of higher order aberrations, models to establish the relative visual effect of aberrations, a method for designing contact lenses, a method in which the VPDF is used to optimise the design of both the front and back surface of the lens, methods for designing surgical procedure, and methods of ocular surgery.

La présente invention concerne un procédé permettant de normaliser l'effet visuel de différentes aberrations d'ordre supérieur par rapport à l'effet visuel produit par la défocalisation. Cette invention concerne également un facteur de correction qui va normaliser la moyenne quadratique (RMS), un tableau d'optotypes servant à mesurer les effets d'aberrations d'ordre supérieur, des méthodes pour tester les effets d'aberrations d'ordre supérieur, des modèles permettant d'établir l'effet visuel relatif d'aberrations, un procédé de conception de lentilles de contact, un procédé consistant à utiliser le facteur défavorable à la performance visuelle (VPDF) pour optimiser la conception des surfaces avant et arrière de la lentille, des procédés pour élaborer une procédure chirurgicale ainsi que des méthodes de chirurgie oculaire.
