Abstract
The invention relates to a device for cutting the human cornea (45) using a focused laser beam comprising controllable components for adjusting the location of the beam focus, a control computer for controlling said components and a control program for the control computer. Said control program contains instructions that are designed to produce cuts (38, 40, 43) in the cornea according to a predetermined cutting pattern when said instructions are carried out by the control computer. Said cutting pattern defines a cornea bed (42), a flap (36) arranged on the bed (36) and at least one strip of cornea tissue (46) which extends along the flap edge in the region of the peripheral edge of the flap between the bed and the flap. Once the flap is folded away, said tissue strip can be removed and the flap (36) can be folded back onto the surface of the bed (42) in a fold-free, post-ablative manner. The visual damage to microstrips can also be avoided.

Claims (14)
1. Device for machining the human cornea (45) with focused laser radiation, with controllable components (16) for setting the location of the radiation focus, with a 5 control computer (30) for controlling these components, and with a control program (34) for the control computer, the control program containing instructions that have been designed to bring about, upon execution by the control computer, the genera tion of incisions (38, 40, 43) in the cornea in accordance with a predetermined inci sion figure, the incision figure defining a corneal bed (42), a flap (36) situated on the 10 bed and also at least one tissue strip (46) situated in the region of the peripheral edge of the flap between the bed and the flap and extending along the edge of the flap.
2. Device according to Claim 1, wherein the tissue strip (46) extends substantially 15 over the entire peripheral length of the edge of the flap.
3. Device according to Claim 1, wherein the tissue strip (46) extends only over a part of the peripheral length of the edge of the flap. 20
4. Device according to Claim 3, wherein the incision figure defines a plurality of at least two tissue strips which extend along different peripheral regions of the edge of the flap.
5. Device according to one of the preceding claims, wherein the tissue strip (46) is 25 situated completely beneath the anterior surface (48) of the cornea.
6. Device according to one of the preceding claims, wherein the tissue strip (46) has variable cross-section in the peripheral direction of the edge of the flap. 30
7. Device according to one of the preceding claims, wherein the cross-section of the tissue strip (46) has increasing width when viewed in the direction from the ante rior surface (48) of the cornea towards deeper regions of the cornea (45).
8. Device according to one of the preceding claims, wherein the cross-section of 35 the tissue strip (46) is approximately wedge-shaped. - 15
9. Device according to one of the preceding claims, wherein the incisions (38, 40, 43) include a first incision (38), defining the underside of the flap, situated totally deep within the cornea (45) and preferentially extending parallel to the anterior sur face (48) of the cornea, and also two second incisions (40, 43), spaced from one 5 another, in particular running into the first incision in angled manner and delimiting the tissue strip (46) between themselves and the first incision, of which at least one is conducted out to the anterior surface of the cornea.
10. Device according to Claim 9, wherein the two second incisions (40, 43) run into 10 one another beneath the anterior surface (48) of the cornea.
11. Device according to one of the preceding claims, wherein the control computer (30) has access to ablation data that are representative of a corneal ablation profile, the control computer having been set up to determine, on the basis of the ablation 15 data, the incision figure, in particular the cross-section of the tissue strip (46), in a manner depending on the peripheral location of the edge of the flap.
12. Process for machining a human eye, including: - generating incisions in the cornea of the eye by means of first focused laser radia 20 tion in accordance with a predetermined incision figure, the incision figure defining a corneal bed, a flap situated on the bed and also at least one corneal tissue strip situated in the region of the peripheral edge of the flap between the bed and the flap and extending along the edge of the flap, - folding the flap upwards, 25 - removing the at least one tissue strip, - ablating the exposed bed tissue by means of second focused laser radiation in accordance with an ablation profile, - folding the flap back. 30
13. Process according to Claim 12, further including: - determining the incision figure on the basis of the ablation profile.
14. Process according to Claim 13, wherein the determining of the incision figure includes: 35 - ascertaining a length-difference, existing after the ablation in comparison with be fore the ablation, of at least one line segment measured across the bed surface, - 16 - establishing the cross-section of the at least one tissue strip on the basis of the ascertained at least one length-difference.
