Abstract[English]
In certain embodiments, an ophthalmic laser surgical system for imaging and treating a target in an eye includes an imaging system with an optical coherence tomography (OCT) device that directs an OCT imaging beam along an imaging beam path towards the target in the eye, and generates OCT images from the OCT imaging beam reflected from the eye. The beam combining and alignment device aligns the OCT imaging beam and the laser beam. The laser-OCT xy-scanner: receives the OCT imaging beam from the imaging system, directs the OCT imaging beam along the imaging beam path towards the eye, and scans the OCT imaging beam in an xy-plane in the eye; and receives the laser beam from the laser device, directs the laser beam along the laser beam path aligned with the imaging beam path towards the eye, and scans the laser beam in the xy-plane in the eye.[French]
Dans certains modes de réalisation, un système de laser chirurgical ophtalmique pour l'imagerie et le traitement d'une cible dans un œil comprend un système d'imagerie comportant un dispositif de tomographie par cohérence optique (OCT) qui dirige un faisceau d'imagerie OCT le long d'un trajet de faisceau d'imagerie en direction de la cible dans l'œil, et qui génère des images OCT à partir du faisceau d'imagerie OCT réfléchi par l'œil. Le dispositif de combinaison et d'alignement de faisceau aligne le faisceau d'imagerie OCT et le faisceau laser. L'ensemble laser-scanner xy OCT : reçoit le faisceau d'imagerie OCT provenant du système d'imagerie, dirige le faisceau d'imagerie OCT le long du trajet de faisceau d'imagerie en direction de l'œil, et balaye le faisceau d'imagerie OCT dans un plan xy dans l'œil ; et reçoit le faisceau laser en provenance du dispositif laser, dirige le faisceau laser le long du trajet de faisceau laser aligné avec le trajet de faisceau d'imagerie en direction de l'œil, et balaie le faisceau laser dans le plan xy dans l'œil.
