Abstract[English]
In certain embodiments, a system for detecting an intraocular lens (IOL) in an image of an eye includes an imaging system and a computer system. The imaging system generates the image of the eye. The eye has multiple structures, including the IOL. The computer system receives the image of the eye from the imaging system and detects one or more Purkinje image(s) in the image of the eye. A Purkinje image comprises a reflection from a structure of the eye. The computer system uses the Purkinje image(s) to detect one or more surface(s) of the IOL and determines a location of the IOL according to the surface(s) of the IOL.[French]
Dans certains modes de réalisation, un système de détection d'une lentille intraoculaire (LIO) dans une image d'un oeil comprend un système d'imagerie et un système informatique. Le système d'imagerie génère l'image de l'oeil. L'oeil a de multiples structures, y compris la LIO. Le système informatique reçoit l'image de l'oeil du système d'imagerie et détecte une ou plusieurs images de Purkinje dans l'image de l'oeil. Une image de Purkinje comprend une réflexion d'une structure de l'oeil. Le système informatique utilise la ou les images de Purkinje pour détecter une ou plusieurs surfaces de la LIO et détermine un emplacement de la LIO en fonction de la ou des surfaces de la LIO.
