Abstract[English]
In certain embodiments, an ophthalmic laser surgical system for treating a floater in a vitreous of an eye includes a floater detection system, a laser device, and a computer. The floater detection system determines the location of the floater in the vitreous of the eye. The laser device directs a laser beam along a laser beam path towards the floater. The computer accesses a three-dimensional scan pattern for the laser beam that yields a three-dimensional pulse pattern of laser pulses. The three-dimensional pulse pattern has a bubble shield pulse pattern at the posterior side of the three-dimensional pulse pattern. The bubble shield pulse pattern forms a bubble shield that reduces laser radiation exposure at a retina of the eye. The computer instructs the laser device to direct the laser beam towards the floater according to the three-dimensional scan pattern.[French]
Dans certains modes de réalisation, un système de chirurgie ophtalmique au laser pour traiter un corps flottant dans le vitré d'un œil comprend un système de détection de corps flottant, un dispositif laser et un ordinateur. Le système de détection de corps flottants détermine l'emplacement du corps flottant dans le vitré de l'œil. Le dispositif laser dirige un faisceau laser le long d'une trajectoire de faisceau laser vers le corps flottant. L'ordinateur accède à un modèle de balayage tridimensionnel pour le faisceau laser qui produit un diagramme d'impulsion tridimensionnel d'impulsions laser. Le diagramme d'impulsions tridimensionnel comporte un diagramme d'impulsions de bouclier sphérique sur le côté postérieur du diagramme d'impulsions tridimensionnel. Le diagramme d'impulsions du bouclier sphérique forme un bouclier sphérique qui réduit l'exposition de la rétine de l'œil au rayonnement laser. L'ordinateur commande le dispositif laser pour qu'il dirige le faisceau laser vers le corps flottant en fonction du modèle de balayage tridimensionnel.
