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 (), the treatment device being positioned downstream from said femtosecond laser, remarkable in that the treatment device comprises an optical focusing system () for focusing the L.A.S.E.R. beam in a cutting-out plane, and a control unit () 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.

Optical focusing system of an apparatus for cutting-out a human or animal tissue

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 (), and positioned downstream from said femtosecond laser, the treatment device comprising:

Sweeping optical scanner of an apparatus for cutting-out a human or animal tissue

A device for cutting human or animal tissue including a femtosecond laser that can emit a L.A.S.E.R. beam in the form of impulses. The device directs and focuses the beam onto or into the tissue for the cutting thereof. The device further includes and element to shape the L.A.S.E.R. beam, positioned in the trajectory of the beam, and to modulate the energy distribution of the L.A.S.E.R. beam in the focal plane thereof, corresponding to the cutting plane.
