摘要： The invention relates to a device for producing control data for controlling a laser device (L) for the surgical correction of the defective vision of an eye (3) of a patient (4), the control data being adapted to control a laser device (L) which cuts cornea tissue by irradiation of laser radiation (2) onto the cornea (5) of the eye (3). The device (12) produces the control data in such a manner that the laser device (L), when operated according to the control data, emits the laser radiation (2) in such a manner that a volume (18) in the cornea (5) is isolated, the removal of said volume from the cornea (5) resulting in the desired correction of the defective vision. The device (12) calculates a radius of curvature R
CV * to determine the control data, the cornea (5) reduced by the volume (18) having said radius of curvature R
CV * and said radius of curvature being site-specific and satisfying the following equation: R
CV *(r,φ) = 1 / ( (1/R
CV (r,φ)) + B
COR (r,φ)/ (n
c -1 )) + F, wherein R
CV (r,φ) is the local radius of curvature of the cornea (5) before the volume (18) is removed, n
c is the refractive index of the material of the cornea (5), F is a coefficient, and B
COR (r,φ) is the local change in refractive force required for the desired correction of defective vision in a plane lying in the vertex of the cornea (5), and at least two radii r1 and r2 satisfy the equation B
COR (r=r1,φ) ≠ B
COR (r=r2,φ).

摘要： The invention relates to a method for producing cuts (9) in a transparent material, in particular in the cornea (5), by creating optical openings (8) in said material (5) by means of laser radiation (3) that is focused in said material (5), whereby the focal point (7) is displaced in order to produce the cut (9) from a surface grid-type array (F) of optical openings (8) arranged in sequence. The focal point (7) is displaced along a trajectory and optical openings (8) along said trajectory that are adjacent are not produced immediately after one another. In addition, the surface grid-type array (F) of optical openings (8) is constructed from at least two sub-grids (G,1, G2, G3), the optical openings (8) of which are processed sequentially grid by grid.

摘要： The invention relates to a method for forming curved cuts (9) in a transparent material, in particular in the cornea (5), by the creation of optical perforations (8) in said material (5) using laser radiation (3) that is focussed in the material (5). The focal point is displaced three-dimensionally (7) to form the cut (9) by lining up the optical perforations (8). The focal point (7) is displaced in a first spatial direction (z) by a displaceable lens (6) and said focal point (7) is guided in relation to the two remaining spatial directions (x, y) in such a way that it follows the contours (17) of the cut (9), which lie on a plane that is perpendicular to the first spatial direction (z).

摘要： The invention relates to a device for measuring an optical penetration that is triggered in a tissue (6, 14) underneath the tissue surface by means of therapeutic laser radiation which a laser-surgical device (5) concentrates in a treatment focus (11) located in said tissue (6, 14). The inventive device is provided with a detection beam path comprising a lens system which couples radiation emanating from the tissue (6, 14) underneath the tissue surface into the detection beam path. A detector device (4, 3, 9; 39, 40, 41; 58, 59, 60) generating a detection signal (5) which indicates the spatial dimension and/or position of the optical penetration in the tissue (6, 14) is arranged downstream of the detection beam path.
