摘要： A method for generating control data to control a laser device for correcting defective vision. A cut surface is specified which is curved, has a vertex and an edge, and is to be created in the eye. One or more paths, along which a focus of the laser radiation is to be adjusted, are defined for the control data and are selected such that they lie on or near the cut surface. To select the paths, a reference plane, preferably perpendicular, with respect to a direction of incidence of the laser radiation is determined, and different displacement positions are determined for said reference plane from the vertex to the edge of the cut surface. Multiple axes or semi-axes are determined for each displacement position. Intersections of the axes are connected into closed curves which are concentric or form a spiral.

摘要： A device for producing control data for a laser device for the surgical correction of defective vision. The device produces the control data such that the laser emits the laser radiation such that a volume in the cornea is isolated. The device calculates a radius of curvature RCV* to determine the control data, the cornea reduced by the volume having the radius of curvature RCV* and the radius of curvature being site-specific and satisfying the following equation: RCV*(r,φ)=1/((1/RCV(r,φ))+BCOR(r,φ)/(nc−1))+F, wherein RCV(r,φ) is the local radius of curvature of the cornea before the volume is removed, nc is the refractive index of the material of the cornea, F is a coefficient, and BCOR(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, and at least two radii r1 and r2 satisfy the equation BCOR(r=r1,φ)≠BCOR(r=r2,φ).

摘要： With some ophthalmological instruments, the patient to be examined or treated needs to gaze in a defined direction. Accordingly, the operator needs the most objective possible information as to whether the patient actually fixates the fixating target or when this may no longer be the case. The invention makes it possible to monitor fixation economically with a short reaction time and with high accuracy. Monitoring of the fixation of an eye is accomplished in an economical manner with a short reaction time and high accuracy through spectroscopic detection of fixation, particularly by identifying a reflection at the fovea or foveola based on different reflectance factors compared to the rest of the retina.

The laser device separating corneal tissue by applying laser radiation. The control device controls the laser device for emitting the laser radiation into the cornea such that a lenticule-shaped volume is isolated. Removal thereof effects the desired correction. The control device (12) predefines the volume such that a posterior surface and an anterior surface are connected via an edge surface that has a width in projection along the visual axis that is wider than the one which a straight line in the same projection, that is perpendicular at the edge of the posterior or the anterior surface would have relative to the associated surface and connects the anterior surface to the posterior surface or to the perceived extension thereof.

摘要： A method of preparing an apparatus for material processing by generating optical breakthroughs in an object. The apparatus includes a variable focus adjustment device. A contact element is mounted to the apparatus, the contact element has a curved contact surface having a previously known shape. The position of the contact surface is determined prior to processing the object, by focusing measurement laser radiation near or on the surface by the variable focus adjustment device, and the focus position is adjusted in a measurement surface intersecting the expected position of the contact surface. Radiation from the focus of the measurement laser radiation is confocally detected. The position of points of intersection between the measurement surface and the contact surface is determined from the confocally detected radiation to determine the position of the contact surface from the position of the points of intersection and the previously known shape of the contact surface.
