摘要： An arrangement and method for positioning an ophthalmologic device with respect to the patient's eye to be examined in x-, y- and/or z-coordinates. The device includes a controllable illumination unit, an observation system, an image recording unit, a central control unit, an output unit, an eye tracker unit, and a device for relative positioning. The imaging system of the eye tracker unit has at least two different adjustable magnifications. In positioning the ophthalmologic device, the signal of the eye tracker unit is used to track a measuring mark and/or grid structure projected on the eye, and also to detect the position of the patient's eye with respect to the optical axis of the ophthalmologic device. The inventive solution makes it possible to automatically position the entire device with respect to the eye to be examined, thus simplifying examination and accelerating determination of biometric data.

摘要： A subassembly for generating an optically active slit with a changeable slit width s, preferably for slit lamps, with two slit jaws which are displaceable relative to one another at a straight-line guide and between which the slit is formed, wherein one of two guide paths is allocated to each slit jaw. In a subassembly for generating an optically active slit, the guide paths are formed at portions of a guide rail which project out freely in the displacement directions of the slit jaws from a clamping position which is fixed with respect to the frame. The guide rail can accordingly expand without hindrance in the displacement direction under the influence of temperature without the parallelism of the slit being affected thereby.

摘要： Illumination unit for the generation of optical sectional images in transparent media, particularly in the eye is disclosed. In the arrangement according to the invention, the low-divergence beams emitted by a laser serving as illumination source are imaged on or in the eye under examination by a reflection element which is controllable in a defined manner and beam deflection elements present in the beam path. The optical sectional images resulting in and on the eye can be observed and/or recorded, further processed and evaluated with an image processing unit in a known manner. In the solution according to the invention, a sectional image is generated by the deliberate periodic beam deflection of a particularly fine laser beam with high depth of focus, which sectional image remains sharp through the entire dimension of the object to be examined and makes possible an improved evaluation. The intensity of the laser beam bundle can be varied in such a way that it is sufficient for observation and documentation, but so that the diameter of the beam bundle is fine enough for a high detail resolution.

摘要： The present invention is directed to an arrangement for generating a variable illumination and irradiation for diagnosis and therapy, particularly for the human eye (1), and to a method for the application thereof. The object to be illuminated can be an artificial object or biological tissue. The arrangement for carrying out the illumination/irradiation of a human eye (1) comprises an illumination unit (2, 3), an optical imaging system (4), an evaluating unit, a central control unit (6) and an output unit (7). The illumination unit (2, 3) generates an illumination which is variable with respect to time and/or space and which is adapted to the diagnostic results. The solution according to the invention is provided chiefly for post-operative fine adjustment of the refractive power of photosensitive plastics already implanted in the eye (1). The latter can be optical lenses as well as other optical elements which are placed in a specific manner in the cornea. However, application of the invention for achieving dermatological effects is also conceivable.

摘要： The present invention is directed to an arrangement and a method for eye examination and/or for determining biometric eye data in which the movement of the eyes is compensated through the use of an eye tracker unit. The arrangement comprises a controllable digital illumination unit and an observation system which are arranged on separate supporting arms. A central control unit has connections to an image recording unit, an optical imaging system, an eye tracker unit and an output unit. Further, transmitter elements and/or actuating drives are provided at the separate supporting arms, at the zoom system and at the magnification changer. The examination can be adapted in an optimal manner to the task at hand by means of the structured illumination patterns that can be generated in a variable manner. Detection of all adjusting parameters relevant for recording can be used for calculations and for reconstructing the pertinent observation conditions. In case of repeated examinations for determining changes, e.g., during the recovery process following eye surgery, the regions can be found again in a simple manner and examined under exactly the same conditions.
