Abstract[English]
In certain embodiments, an ophthalmic surgical system for viewing an eye includes an ophthalmic microscope and a laser device. The ophthalmic microscope receives light reflected or scattered backwards from within the vitreous of the eye in order to provide an image of an object within the vitreous. The ophthalmic microscope includes a slit illumination source (which includes a light source and an optical element), a spectral filter, and oculars. The slit illumination source illuminates the eye with light, where the light source provides the light, and the optical element directs the light into the eye. The spectral filter filters out red spectral components of the light. The oculars receive the light from the eye in order to provide the image of the object. The laser device generates a laser beam to direct towards the object within the eye.[French]
Dans certains modes de réalisation, un système chirurgical ophtalmique de visualisation d'un œil comprend un microscope ophtalmique et un dispositif laser. Le microscope ophtalmique reçoit la lumière réfléchie ou diffusée vers l'arrière depuis l'intérieur de l'humeur vitrée de l'œil afin de fournir une image d'un objet à l'intérieur de l'humeur vitrée. Le microscope ophtalmique comprend une source d'éclairage en fente (qui comprend une source de lumière et un élément optique), un filtre spectral et des oculaires. La source d'éclairage à fente éclaire l'œil avec de la lumière, la source de lumière fournissant la lumière, et l'élément optique dirigeant la lumière dans l'œil. Le filtre spectral filtre les composantes spectrales rouges de la lumière. Les oculaires reçoivent la lumière provenant de l'œil afin de fournir l'image de l'objet. Le dispositif laser génère un faisceau laser à diriger vers l'objet à l'intérieur de l'œil.
