    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: An ophthalmological measuring system, for obtaining biometric data of an eye, provided with the necessary calibration and check devices for monitoring the functionality and the calibration status. The ophthalmological measuring system includes an illumination source for illuminating an eye with light and with a sensor for recording and analyzing back-scattered or reflected light components and a controller. At least one calibration and check system integrated in the ophthalmological measuring system for monitoring the functional and calibration status is provided. A device is also provided which houses the calibration and test structures and which reads off the individual physical data therefrom by an interface. The ophthalmological measuring system is in particular provided for determining biometrical data but can also be used for ophthalmological, dermatological or other devices which require calibration and/or functional checking at regular intervals.

    摘要: The present invention is directed to a solution for measuring geometric parameters in the eye which are required for calculating the refractive power of intraocular lenses. The device according to the invention for axial length measurement which acquires axial length, anterior corneal radii, anterior chamber depth, and other parameters in the anterior eye segment includes a control unit, a first measuring device for determining axial length, and an additional measuring device which acquires a plurality of structures in the anterior segment (such as the cornea, anterior chamber, and lens) and which has at least one illumination unit and at least one image recording unit. By determining additional partial-distance parameters of the anterior eye segments, the IOL can be calculated with high precision even after refractive surgery in which the natural relationship between the radii of the anterior and posterior corneal surfaces is extensively altered by corneal surgery.

    摘要: The present invention is directed to an arrangement by which the image field of the illumination components and irradiation components of ophthalmic instruments for diagnosis and therapy is improved. In the arrangement according to the invention, one or more diffractive optical elements is/are arranged additionally in the illumination beam path for deliberate shaping of the image plane in the eye to be irradiated. These diffractive optical elements can be located on the surface of other optical elements, swiveled into the illumination beam path, and their wavelength changed by filters. The image plane can be adapted to the spherical contour of the eye so that the projected characters and structures have a uniformly high image quality in the center and in the edge area of the eye. The present invention is applicable for variable illumination for diagnosis and treatment of the eye, in particular for irradiation of the eye lens and other parts of the eye such as the cornea or retina. The arrangement can be used in a great variety of ophthalmic instruments such as fundus cameras, slit lamps, laser scanners, OPMI instruments or surgical microscopes.

    摘要: The present invention is directed to a method and an arrangement for automatic detection, documentation and reproduction of the adjusted magnification. The magnification steps are read off at the rotational axis of the magnification changer, monitored by a control unit and stored for reproducing the magnification setting. For this purpose, a cylinder is arranged on the rotational axis of the magnification changer, this cylinder having a quantity of magnets with radially oriented magnetic fields which divide the cylinder into segments. An arrangement of sensors which are fixedly connected to the housing is located opposite from these magnets for detection of their magnetic fields. The quantity and arrangement of sensors correspond to the quantity and arrangement of magnets. The solution supports a comprehensive computer-assisted control of the instruments and offers the possibility of defined standardized sequences. Further, it is possible to let the magnification step be adapted to the observation task automatically or to ensure remote control capability through voice control.
