20110190741 | Coupling of an eye to a laser device - According to an exemplary embodiment, a process for coupling a mechanical interface unit to a suction-ring unit retained on an eye by suction force includes a step of relative approximating of the interface unit to the suction-ring unit in an axial direction as far as a first, predetermined relative position of the two components, which is preferentially detected by suitable sensorics. When the first relative position is attained, the evacuation is begun of a suction chamber formed between the interface unit, the suction-ring unit and the surface of the eye, whereby the partial vacuum generated establishes in the suction chamber a contact between the surface of the eye and an applanation plate retained on the interface unit, or enlarges a region of existing contact. The aspirating of the eye onto the applanation plate prevents compression loads and shear loads on the eye such as normally cannot be avoided when impressing the plate onto the eye. | 08-04-2011 |

20120172853 | Apparatus for ophthalmic laser surgery - An apparatus for ophthalmic laser surgery comprises a contact surface for formative bearing contact of an eye to be treated, components for providing focussed, pulsed treatment laser radiation and for directing the same through the contact surface onto the eye, a measuring device for measuring the position of the contact surface along the direction of propagation of the treatment laser radiation, the measuring device providing position data representing the measured position of the contact surface at least one location of the contact surface, and an electronic process and control unit, which is connected to the measuring device and which is adapted to control the focus position of the treatment laser radiation in dependence on the position data. By measuring the position of the contact surface, the laser-surgery apparatus provides for compensation of unavoidable manufacturing tolerances of a contact element forming the contact surface, and thereby provides for precise referencing of the front surface of the eye in relation to the laser-surgery apparatus. | 07-05-2012 |
20120206720 | METHOD AND DEVICE FOR EXAMINING A LASER SYSTEM - A method for analyzing a laser system, which has a focused laser beam and a controllable deflection assembly for controlling the transverse and/or longitudinal position of the beam focus, said method comprising the steps of directing the laser beam or a partial beam branched therefrom downstream of the deflection assembly toward an optically nonlinear medium for the purpose of generating frequency multiplied radiation, the wavelength of which corresponds to an uneven higher harmonic of the wavelength of the laser beam, activating the deflection assembly, and measuring a power of the frequency multiplied radiation while the deflection assembly is activated. The conversion efficiency of the nonlinear process by which the frequency multiplied radiation is produced is dependent upon the focusability of the laser beam. By evaluating the measured power of the frequency multiplied radiation, dynamic impairments of focusability can be detected, which can be caused by inertia-induced deformations of optical scan components of the laser system. | 08-16-2012 |
