Abstract: A device for altering an optical and/or mechanical property of a lens that is implanted in an eye, the device including a laser device, which has a laser beam source that provides a pulsed laser beam and an optical unit, which impinges on the implanted lens with the pulsed laser beam. The device also includes a control device, which controls the laser device such that the optical and/or mechanical property of the lens is altered on the basis of non-linear interaction between the laser beam and the lens material.

Abstract: 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.

Abstract: A weather-proof notification device includes an enclosure having an integrally formed grille and a speaker located within and attached to the enclosure proximate the grille. The grille is configured to inhibit the entry of rainwater into the interior of the enclosure. A water-resistant or water-tight seal is provided between the speaker and the enclosure, and the speaker includes a water-repellent diaphragm, in order to prevent water from migrating from the sound chamber into the operating electrical compartment. A drain is provided on the grille to permit free drainage of water from the sound chamber.

Abstract: For defined ablation of a surface, successive partial regions of equal surface area are acted on by a radiation source, preferably a laser, through an optical system. The partial regions are smaller as regards surface area than the whole surface to be processed, so that the respective radiation source can be dimensioned in a less costly manner. Telescope optics with conical surfaces serve as optical systems suitable for this purpose.
