摘要:
The invention relates to a device for producing at least one continuous slit-shaped cut (42) from the rear surface (48) to the front surface (46) of the cornea (44) of a human eye, comprising a laser device for producing at least one part of the cut using focused pulsed laser radiation, wherein the laser device comprises controllable components for setting the location of the focus, a control computer for controlling said components, and a control program for the control computer. The control program contains instructions, which are designed to cause the creation of at least one part of the cut (42) starting from the rear surface (48) of the cornea when said instructions are executed by the control computer, wherein the cross- sectional course of the cut - observed in the direction from the front surface to the rear surface, deviates from a straight line (60) perpendicular to the eye surface. According to a preferred embodiment, the cross-sectional course of the cut has several straight-line sections (50, 52, 54), which follow each other in the manner of a zig-zag pattern and each pair of which is separated by a kink (56, 58).
