Abstract (en)

[origin: WO2004017878A1] The invention relates to a laser-based device for non-mechanical, three-dimensional trepanation during cornea transplants, said device comprising a computer-assisted control and regulation unit (4) provided with at least one control computer (5, 6, 7) and at least one display unit (8, 9), a laser source (2) for generating a working laser beam (3), and a multisensor processing head (1) into which the following items are integrated: an axial beam positioning system (11) into which the working laser beam (3) can be coupled, a focal point tracking unit (12) for the displacement of the focal point (13) of the working laser beam (3) into position z, an x-y scanner unit (14, 15) for the displacement of the working laser beam (3) into positions x and y, an eye position sensor unit (23, 24, 35, 36) for detecting the position of the eye, and a plasma sensor unit (16, 25) for detecting the plasma light occurring during the cornea trepanation.
