Abstract
(EN)
Systems and methods for modifying an eye including a light source with light elements, a photodetector producing a signal representing images of the light elements and corresponding to locations on an ocular surface, an optical system directing light from the light elements reflected by the ocular surface onto the photodetector, a memory including code for processing the signal, and a processor for executing the code and outputting shape data for use in calculating a treatment plan for the eye. The code includes instructions for determining the shape data based on a combination of zonal reconstruction and polynomial fitting using the plurality of images.

La présente invention a pour objet des systèmes et des méthodes permettant de modifier un œil, comprenant une source de lumière pourvue d'éléments lumineux, un photodétecteur produisant un signal représentant des images des éléments lumineux et correspondant aux emplacements d'une surface oculaire, un système optique dirigeant la lumière issue des éléments lumineux réfléchie par la surface oculaire sur le photodétecteur, une mémoire comprenant un code pour le traitement du signal, et un processeur pour l'exécution du code et la production en sortie de données de forme destinées à être utilisées dans le calcul d'un plan de traitement pour l'œil. Le code comprend des instructions pour la détermination des données de forme basées sur une association d'une reconstruction zonale et d'un ajustement polynomial utilisant la pluralité d'images.
