Abstract
A laser system serves for corneal grafting by photodisruptive laser cutting. To this end, short laser pulses within the range from 1 fs to 10 ns are positioned and guided in the cornea in such a way that the foci (20) of the laser pulses describe an incision path in the cornea (12) that exhibits an undercut, so that a seal between the juxtaposed surfaces of the implant and of the residual cornea arises between a donor implant and the recipient cornea which is promoted by the overpressure of the eye
