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 |
20100060728 | METHOD FOR PRODUCING HIGH-QUALITY REPRODUCTIONS OF THE FRONT AND/OR REAR SECTIONS OF THE EYE - The present invention makes it possible to make high-quality recordings of the anterior and/or posterior segments of the eye as an individual image or also as a sequence of images without increasing the radiation load on the eye to be examined. In the method according to the invention, at least one pre-flash is used in order to determine an optimal exposure time for the main flash based on the recording of the pre-flash which is reflected by the object to be recorded. Both the pre-flash and the main flash are controllable and the recordings of the pre-flash and main flash are recorded with the same sensor of the electronic camera and are evaluated electronically by a control unit, and the recording of the main flash and, as the case may be, of the pre-flash is analyzed and/or corrected and displayed to the user. | 03-11-2010 |
20100137849 | MULTIPLE-SPOT LASER REFRACTIVE OPHTHALMIC SURGERY - An apparatus for material processing by laser radiation, including a laser source which emits a processing beam, and a beam path for focusing and scanning, the beam path focusing the processing beam into a processing volume and shifting the position of the focus therein. A beam splitting device generates several foci in the processing volume and the beam splitting device splits the processing beam up into a primary beam and at least one secondary beam and leaves the cross section of the beam in a pupil plane of the beam path unchanged during said division and introduces an angle of separation between the primary and secondary beams, so that these beams expand in the beam path in directions which differ by the angle of separation. | 06-03-2010 |
20100277695 | APPLICATOR FOR AN OPHTHALMOLOGIC TREATMENT DEVICE - An applicator for an ophthalmologic treatment or diagnostic device, wherein a laser beam and an illumination beam are directed at the eye and light reflected from the eye is fed to an examining beam path. A reflective surface is provided for the reflection of the illumination beam and comprises an optical aperture for the laser beam. | 11-04-2010 |
20110264209 | Ophthalmologic Implant - The invention relates to an ophthalmologic implant, in particular an intraocular lens, comprising at least one marker ( | 10-27-2011 |
20130231644 | MULTIPLE-SPOT LASER REFRACTIVE OPHTHALMIC SURGERY - An apparatus for refractive ophthalmic surgery by laser radiation including a source of radiation which emits a processing beam a beam path for focusing and scanning. The beam path focuses the processing beam into a cornea of an eye and shifts a position of a focus therein. A beam splitting device generates several foci in the cornea and divides the processing beam into a primary beam and at least one secondary beam. The primary and secondary beams have substantially the same cross section as the processing beam which is incident on the beam splitting device and the beam-splitting device introduces a separation between the primary and secondary beams. The primary and secondary beams expand in the beam path. A contact glass induces a pre-defined geometric boundary surface at the cornea. | 09-05-2013 |
