Abstract[English]
Real-time instrument position estimation and guidance for ophthalmic surgery are described. An ophthalmic surgical system may include a first camera to obtain a first image feed of an ophthalmic surgical procedure and a second camera to obtain a second image feed of the ophthalmic surgical procedure. The ophthalmic surgical system may further include a real-time instrument position estimation module implemented in a non-transitory computer-readable storage medium and configured to determine, in real-time, a relative position of an instrument feature with respect to an anatomical feature of an eye based on the first image feed and the second image feed during the ophthalmic surgical procedure. The real-time instrument position estimation module may be further configured to output, in real-time, a surgical guidance based on the relative position of the instrument feature with respect to the anatomical feature of the eye during the ophthalmic surgical procedure.[French]
L'invention concerne une estimation et un guidage de position d'instrument en temps réel pour une chirurgie ophtalmique. Un système chirurgical ophtalmique peut comprendre une première caméra pour obtenir un premier flux d'images d'une intervention chirurgicale ophtalmique et une seconde caméra pour obtenir un second flux d'images de l'intervention chirurgicale ophtalmique. Le système chirurgical ophtalmique peut en outre comprendre un module d'estimation de position d'instrument en temps réel mis en œuvre dans un support de stockage lisible par ordinateur non transitoire et configuré pour déterminer, en temps réel, une position relative d'un élément d'instrument par rapport à un élément anatomique d'un œil sur la base du premier flux d'images et du second flux d'images pendant l'intervention chirurgicale ophtalmique. Le module d'estimation de position d'instrument en temps réel peut en outre être configuré pour délivrer, en temps réel, un guidage chirurgical sur la base de la position relative de l’élément d'instrument par rapport à l’élément anatomique de l'œil pendant l'intervention chirurgicale ophtalmique.
