Abstract: An eye implant with an optical implant region for correcting an imaging error of the eye. Biometrically determined data of optically effective components located in front of the retina of the eye is obtained through wave front measurement. The optical implant region is adjusted, based on the biometrically determined data, for a monofocal vision with a visual acuity of at least 0.7 (70%) within a field of focus depth of at least 2 diopters.

Abstract: A system and method are provided in which an iris or eye image is taken during a refractive diagnostic analysis. The image is employed for aligning data from the analysis with data from other refractive analysis instruments, as well as aligning a refractive surgical tool, such as a laser, with the eye for treatment. Further, the stored iris image is compared with the patient's iris before treatment, verifying that the correct eye is to be treated with a developed treatment pattern. A variety of refractive instruments can be used, such as corneal topography systems and wavefront aberration systems.

Abstract: A method and a device for detecting the spatial position of the optical axis of the eye of a human or animal subject and for centering a reference system in relation to the optical axis are described, having at least one light source emitting a parallel light beam bundle, a positioning region for the subject provided opposite the light source, means for relative position orientation of the parallel light beam bundle in relation to the eye of the subject, and at least one detector unit for detecting reflection events caused in and on the eye by the parallel light beam bundle. The present invention generates control signals on the basis of the scattering and reflection events detected by the detector unit, by which the means for relative position orientation are activated, the control signals being generated in such a way that at least one reflection event and at least one scattered light event are to be brought into congruency in relation to the propagation direction of the parallel light beam bundle.

Abstract: An apparatus for the treatment of glaucoma with a laser catheter and a light-conducting fiber arrangement, to the proximal end of which light can be coupled and at the distal end of which a light-emerging surface is provided, with a pressure-sensitive device to achieve a specified contracting pressure of the light-emerging surface.

Abstract: A device is disclosed for selectively improving and/or permanently ensuring the permeability for ocular aqueous humour through the trabecular formations into Schlemm's canal. A small tubular element is provided, whose wall material encloses a hollow duct that presents an open configuration on both ends along the longitudinal extension of the hollow duct, so that the size and the shape of the small tubular element correspond approximately to the internal contour of Schlemm's canal, and the wall material as well as the wall thickness are so selected that upon introduction into Schlemm's canal the small tubular element keeps the canal open and dilates adjacent trabecular formations.

Abstract: A method for determining data for adapting a reflective surface to a desired surface, includes the steps of determining spatial co-ordinates of a multiple number of points of a surface and entering the determined spatial co-ordinates into a computer as a data record. Recorded in the computer are then shape and/or position of a desired surface, with the shape and/or position of the desired surface being variable. The computer calculates for the multiple number of points on the surface the spacing to the desired surface. The spatial co-ordinates and spacings of the multiple number of points are then outputted as a data record for adjusting the surface. By simulating the treatment process on the computer in advance, it is possible to select the optimal treatment process and to eliminate regional unevenness on the cornea.

Abstract: What is described here is a device for dilating and restoring the lacrimal duct on the human eye, through which lacrimal fluid flows from the eye into the nasal cavity. The inventive device is provided with the follow components: a first hollow cannula with a distal end which presents at least one longitudinal gap, a guide passing through the first hollow cannula and having a distal end which dilates the distal end of the first cannula in the region of the gap, a hollow body surrounding the outside contour of the first hollow cannula in the distal zone, as well as a second hollow cannula adapted to be pushed over the first hollow cannula and extending up to the end on the proximal side of the hollow body, which is placed on the first hollow cannula so as to lock the latter and prevent it from axial sliding on the proximal side.

Abstract: In this method, the refraction performance is either measured along the path of rays (5-7) for a multitude of ray paths which are distributed across a surface, each path originating from one point (P), or is given based on empirically established values. Afterwards the distances of the incident rays between the surfaces intersected by the path of rays are measured along the path or are given based on empirically established values, and the required shape of at least one surface intersected by the paths of rays is calculated based on those values so that the paths of rays intersect in one point as accurately as possible. Based on the values derived in this way optical fittings (3) can be calculated which can be placed on the cornea surface (8-10), inserted into the inner cornea, attached to the anterior section (11) of the eye and inserted into the inner part of the eye in order to simulate arithmetically all measures that change the refraction power of the eye before the measure is actually implemented.
