摘要：
The present invention relates to an ophthalmic surgical device comprising a laser source (1) adapted to deliver a laser pulse beam (8) of duration between the picosecond and the nanosecond； a focusing optical system (10) for focusing said laser pulse beam at a focal point (6)； and a laser pulse beam moving system configured to move said focal point (6) along a predetermined path. According to the invention, the laser source (1) generates a laser beam (8) picosecond to nanosecond, focused near a surface (25) of the anterior segment of the eye (4), the focal point ( 6) being located at a non-zero distance d from an optical axis (21) of symmetry of the anterior segment of the eye (4), the displacement system (30) of the laser pulse beam comprises a single degree of freedom in rotation about an axis of rotation (36) so as to move said focal point (6) along a curvilinear path (16) located in an annular zone around the optical axis (21) of symmetry of the anterior segment of the eye (4)； and the ophthalmic surgical apparatus configured with a numerical aperture so as to limit the geometric optical aberrations at the focal point (6) and over the entire curvilinear path (16) in said annular zone around the optical axis (21) of symmetry of the anterior segment of the eye (4). La présente invention concerne un appareil de chirurgie ophtalmique comprenant une source laser (1) adaptée pour délivrer un faisceau d'impulsions laser (8) de durée comprise entre la picoseconde et la nanoseconde； un système optique de focalisation (10) pour focaliser ledit faisceau d'impulsions laser en un point focal (6)； et un système de déplacement du faisceau d'impulsions laser configuré pour déplacer ledit point focal (6) suivant une trajectoire prédéterminée. Selon l'invention, la source laser (1) génère un faisceau d'impulsions laser (8) picoseconde à nanoseconde, focalisé au voisinage d'une surface (25) du segment antérieur de l'œil (4), le point focal (6) étant situé à une d
