Estimating the term…
The invention relates to a device (1) for cutting human or animal tissue, such as a cornea (3), or a crystalline lens, said device comprising a femtosecond laser (2) that can emit a L.A.S.E.R. beam (4) in the form of impulses, and means for directing and focusing said beam onto or into the tissue for the cutting thereof as such. According to the invention, the device comprises means (9) for shaping the L.A.S.E.R. beam (4), which are positioned in the trajectory of said beam, and can modulate the energy distribution of the L.A.S.E.R. beam (4) in the focal plane thereof, corresponding to the cutting plane.
A device for cutting-out a human or animal tissue, such as a cornea, or a lens, said device comprising a femtosecond laser able to emit a L.A.S.E.R. beam as pulses, and means able to direct and focus said beam on or in the tissue for its cutting-out as such, said device being wherein the cutting-out device in that it comprises shaping means 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 in its focal plane, corresponding to the cutting-out plane.
A method of controlling a device for cutting-out a human or animal tissue, such as a cornea, or a lens, said device comprising a femtosecond laser able to emit a L.A.S.E.R. beam as pulses, and means able to direct and focus said beam on the tissue for its cutting-out as such,
