Abstract: The invention concerns a method for determining a minimum value of L.A.S.E.R. energy necessary to form, by using a LASER source, a gas bubble in an ocular tissue, the method comprising: acquisition (200) of a reference image, emission (210) at a sampling point, of a L.A.S.E.R. beam, acquisition (220) of one (or more) current image(s) of the ocular tissue, detection (230) of one (or more) gas bubble(s) by comparing the current image(s) and the reference image, determination (240, 250) of the minimum value based on the detected gas bubble(s).

Abstract: The invention relates to a treatment apparatus including a device for conditioning a LASER beam generated by a femtosecond laser, the conditioning device comprising an optical sweeping scanner (30) and a focusing optical system (40) downstream of the optical sweeping scanner (30), remarkable in that a pivoting mirror (32) of the optical sweeping scanner (30) is positioned between an object focal plane Fobject of the focusing optical system (40) and the focusing system (40).

Abstract: The present invention relates to an apparatus for cutting-out including a device for treating a L.A.S.E.R. beam generated by a femtosecond laser (1), and positioned downstream from said femtosecond laser, the treatment device comprising: a shaping system (3) positioned on the trajectory of said beam, for modulating the phase of the wave front of the L.A.S.E.R. beam according to a modulation set value calculated for distributing the energy of the L.A.S.E.R. beam in at least two impact points forming a pattern in its focal plane, an optical focusing system (5) downstream from the shaping system, the optical focusing system comprising a concentrator module for focusing the phase-modulated L.A.S.E.R.

Abstract: The present invention relates to a coupling interface between a laser source and a tissue (2) to be treated, characterized in that the coupling interface comprises —a ring (3) including: ?a side wall (31), ?a proximal end (311) intended to come into contact with the tissue (2) to be treated, and ?a distal end (312) intended to receive the end of the laser source; —a window (32) transparent to a laser beam generated by the laser source, said window being mounted in a sealed manner on the distal end (312) of the ring (3) in such a way as to close the distal end (312) of the ring (3).

Abstract: The present invention relates to apparatus for cutting out a human or animal tissue, such as a cornea, or a lens, said apparatus including a treatment device for producing a pattern consisting of at least two impact points in a focusing plane from a L.A.S.E.R. beam generated by a femtosecond laser (1), the treatment device being positioned downstream from said femtosecond laser, remarkable in that the treatment device comprises an optical focusing system (5) for focusing the L.A.S.E.R. beam in a cutting-out plane, and a control unit (6) able to control the displacement of the optical focusing system along an optical path of the L.A.S.E.R. beam for displacing the focusing plane in at least three respective cutting-out planes so as to form a stack of surfaces for cutting out the tissue.
