20080208177 | Opthalmological Device - A device for correcting defective vision or corneal disease of an eye combines a device ( | 08-28-2008 |
20090051876 | Presbyopia Correction Program - A method of generating a computer program for control of an apparatus for photorefractive treatment of presbyopia by ablation of corneal tissue or a contact lens, comprising the following steps: | 02-26-2009 |
20110190743 | Presbyopia Correction Program - Systems and methods for treating presbyopia are provided. In one embodiment, a system for photorefractive treatment of presbyopia includes a laser source configured for ablating corneal tissue and a control system in communication with the laser source and configured to control the laser source to ablate conical tissue of a patient to achieve a desired corneal shape. In some instances, the control system controls the laser source by calculating a global optimum regarding curvature and asphericity of the cornea. In some instances, control system controls the laser source by calculating a central steep island and calculating a curvature and asphericity for the rest of the cornea. In some embodiments, a laser source is controlled to ablate the cornea of the patient in accordance with a calculated shape profile to achieve a desired corneal shape. | 08-04-2011 |
20110264082 | APPARATUS FOR THE CROSS-LINKING OF OCULAR TISSUE WITH ELECTROMAGNETIC RADIATION - An apparatus for generating an alteration of biomechanical properties of ocular tissue, into which a photosensitiser ( | 10-27-2011 |
20130281992 | Extracting lenticules for refractive correction - In certain embodiments, refractive correction includes controlling a focus of pulsed laser radiation having ultrashort pulses. A channel is created with the pulsed laser radiation to facilitate separation of the lenticule from the eye. A posterior incision is created with the pulsed laser radiation to form a posterior side of the lenticule. An anterior incision is created with the pulsed laser radiation to form an anterior side of the lenticule. | 10-24-2013 |
20130324984 | DEVICE AND PROCESS FOR MACHINING THE CORNEA OF A HUMAN EYE WITH FOCUSED PULSED LASER RADIATION - A device for machining the cornea of a human eye with focused pulsed laser radiation includes controllable components, a control computer for controlling these components and a control program for the control computer. The control program contains instructions that are designed to generate an incision figure in the cornea permitting the insertion of an intrastromal corneal ring implant. The incision figure includes a ring incision situated totally deep within the corneal tissue and an opening incision extending at right angles to the ring plane of the ring incision from the anterior surface of the cornea or from the posterior surface of the cornea as far as at least the ring incision. The ring incision exhibits, assigned to the opening incision ( | 12-05-2013 |
20150342784 | APPARATUS FOR DISSECTING AN EYE FOR THE INTRODUCTION OF A PHOTOSENSITIZER - An apparatus for dissecting an eye for the introduction of a photosensitizer into tissue of an eye, a cannula device for introducing the photosensitizer, a system comprising the apparatus and the cannula device, and a method for dissecting an eye for the introduction of a photosensitizer are provided. The apparatus comprises a source for laser radiation, a system for guiding and focusing the laser radiation with respect to the tissue of an eye, and a computer for controlling said system. | 12-03-2015 |
20160030243 | TECHNIQUE FOR LASER-CUTTING AN ENDOTHELIAL CORNEAL GRAFT - A method for preparing an endothelial corneal graft is provided. The method comprises: providing a donor cornea; irradiating the donor cornea from an endothelial side thereof with laser radiation to cause a photodisruption in tissue of the donor cornea at a focal point of the radiation; and moving the focal point of the radiation to form an endothelial graft in the donor cornea. By irradiating the donor cornea from the endothelial side thereof, instead of the epithelial side, to cut the endothelial graft, optical inhomogeneities which may develop after death in stromal tissue of the donor cornea leave the laser cutting process substantially unaffected. | 02-04-2016 |
