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).

摘要： An apparatus for creating incisions in a human cornea comprises: a source of pulsed laser radiation; a scanner device for scanning the laser radiation; and a control computer for controlling the scanner device based on a control program, the control program containing instructions that, when executed by the computer, bring about the creation in the cornea of: a flap cut defining a corneal flap that is connected to surrounding corneal tissue through a hinge; and one or more auxiliary cuts in connection with the flap cut for removing gas generated during creation of the flap cut, the one or more auxiliary cuts defining a first channel extending from the flap cut to an anterior surface of the cornea and a reservoir located at least partially deeper within the cornea than the flap cut.

摘要： Proposed is an apparatus for assistance in the implantation of a corneal prosthesis in a human eye. The apparatus comprises a laser device for providing focussed, pulsed laser radiation, and a control program for the laser device. The control program is designed, to create an incision figure in the tissue of the eye by means of the laser radiation, this incision figure allowing the corneal prosthesis to be inserted. The incision figure in this case comprises a bed incision located entirely in the depth of the corneal material and an annular incision, which, within the circumferential line of the bed incision, extends from the latter, along its entire annular circumference, as far as the corneal anterior surface. The incision figure further may comprise an auxiliary incision, which extends from a location of the eye surface outside the circumferential line of the bed incision as far the bed incision.
