20080243109 | Method and Device for Producing Cuts in a Transparent Material - The invention relates to a method for producing cuts in a transparent material, in particular in the cornea, by creating optical openings in said material by means of laser radiation that is focused in said material, whereby the focal point is displaced in order to produce the cut from a surface grid-type array of optical openings arranged in sequence. The focal point is displaced along a trajectory and optical openings along said trajectory that are adjacent are not produced immediately after one another. In addition, the surface grid-type array of optical openings is constructed from at least two sub-grids, the optical openings of which are processed sequentially grid by grid. | 10-02-2008 |

20100049174 | APPARATUS FOR GENERATING A CORRECTING CUT SURFACE IN THE CORNEA OF AN EYE SO AS TO CORRECT AMETROPIA AS WELL AS A CONTACT ELEMENT FOR SUCH APPARATUS - An apparatus for generating a correcting cut surface in the cornea of including a laser unit, which can focus and move pulsed laser radiation; a first contact element; and a control unit, controlling the laser unit which has a standard setting which, when a standard curvature is imposed upon corneal surface by the first contact element, would lead to a standard cut surface. The standard cut surface has a known curvature with respect to a reference surface. The curvature, with respect to the reference surface of the correcting cut surface to be generated deviates from the known curvature of the standard cut surface. The apparatus includes a second contact element adapted to generate the correcting cut surface, which cornea imposes an actual curvature deviating from the standard curvature, thus generating a cut surface using the standard setting results in the correcting cut surface to be generated. | 02-25-2010 |

20120133889 | FIXATION CONTROL DEVICE AND METHOD FOR CONTROLLING THE FIXATION OF AN EYE - 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. | 05-31-2012 |
20130178839 | CONTROL DATA GENERATION FOR THE EYE-SURGICAL TREATMENT OF DEFECTIVE VISION - 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. | 07-11-2013 |
