Abstract[English]
A system includes an imaging device configured to perform three-dimensional imaging of at least a portion of an eye of a patient, such as one or both of an OCT and a 3D camera. A sensor is configured to sense a location of a trocar cannula positioned in the eye of the patient. A controller is configured to receive one or more three-dimensional images from the imaging device and receive coordinates of the trocar cannula from the sensor. The controller generates a three-dimensional map of the eye from the one or more three-dimensional images and the coordinates, the three-dimensional map including a representation of the trocar cannula. The controller further generates guidance for performing an ophthalmic procedure according to the three-dimensional map, such as an instrument envelope and/or instrument path. The controller outputs the guidance to a display device or uses the guidance to control a robotic arm.[French]
Un système comprend un dispositif d'imagerie conçu pour effectuer une imagerie tridimensionnelle d'au moins une partie d'un œil d'un patient, tel qu'une OCT et/ou une caméra 3D. Un capteur est conçu pour détecter un emplacement d'une canule de trocart positionnée dans l'œil du patient. Un dispositif de commande est conçu pour recevoir une ou plusieurs images tridimensionnelles provenant du dispositif d'imagerie et pour recevoir des coordonnées de la canule de trocart de la part du capteur. Le dispositif de commande génère également une carte tridimensionnelle de l'œil à partir desdites une ou plusieurs images tridimensionnelles et des coordonnées, la carte tridimensionnelle contenant une représentation de la canule de trocart. Le dispositif de commande génère aussi un guidage pour effectuer une procédure ophtalmique en fonction de la carte tridimensionnelle, telle qu'une enveloppe d'instrument et/ou un trajet d'instrument. En outre, le dispositif de commande transmet en sortie le guidage à un dispositif d'affichage ou utilise le guidage pour commander un bras robotique.
