Abstract[English]
In certain embodiments, an ophthalmic surgical laser system for imaging and treating an eye floater includes an SLO subsystem, a treatment laser subsystem, a scanner, optical elements, and a computer. The SLO subsystem provides an SLO laser beam with an SLO focal point, and the treatment laser subsystem provides a treatment laser beam with a treatment focal point that spatially coincides with the SLO focal point. The scanner scans the SLO laser beam across a scan region and directs the treatment laser beam to the xy-location of the scan region. The optical elements aim the SLO laser beam and the treatment laser beam at substantially the same point of the scan region. The computer receives an SLO image of the floater, determines an xy-location of the floater, and instructs the treatment laser subsystem to direct the treatment laser beam towards the xy-location and the z-scan location of the floater.[French]
Dans certains modes de réalisation, l'invention concerne un système laser chirurgical ophtalmique pour l'imagerie et le traitement d'un corps flottant dans l'œil, comprenant un sous-système de SLO, un sous-système laser de traitement, un dispositif de balayage, des éléments optiques et un ordinateur. Le sous-système de SLO fournit un faisceau laser de SLO avec un point focal de SLO, et le sous-système laser de traitement fournit un faisceau laser de traitement avec un point focal de traitement qui coïncide spatialement avec le point focal de SLO. Le dispositif de balayage amène le faisceau laser de SLO à balayer une région de balayage et dirige le faisceau laser de traitement vers l'emplacement xy de la région de balayage. Les éléments optiques dirigent le faisceau laser de SLO et le faisceau laser de traitement sensiblement au même point de la région de balayage. L'ordinateur reçoit une image de SLO du corps flottant, détermine un emplacement xy du corps flottant et ordonne au sous-système laser de traitement de diriger le faisceau laser de traitement vers l'emplacement xy et l'emplacement de balayage z du corps flottant.
