    摘要: The invention is directed to an optical system for a fundus camera for reflection-free opthalmoscopy having a beam path with refractive and reflective optical elements which are used substantially in common for illumination and observation or recording. An imaging mirror system substantially comprising a plurality of reflecting optical elements in the form of mirrors and is provided for illuminating and imaging the fundus. At least one optical element, for example, mirror, is formed as a freeform mirror with an imaging, reflecting freeform surface. The optical elements are arranged in a housing in a precisely defined position and attitude relative to one another in such a way that an imaging of the reflecting surfaces of the optical elements on the image of the imaged retina is prevented within a wide diopter range of the patient's eye to be examined.

    摘要: There is now provided a method for determining vision defects and for collecting data for correcting vision defects of the eye. The method comprises projecting an image into the eye of the patient with an adaptive optical system having adaptive optical elements. The optical characteristics of the optical elements can be individually changed by an electrical signal. The presence of distortions of the image as perceived by the patient is determined by interaction of the patient with the examiner. By way of an electronic control system the optical characteristics of the adaptive optical elements are changed through outputting of an electrical signal to obtain a modified image with minimized distortions in the eye of the patient. The optical characteristics of the adaptive optical elements, as modified, are determined and vision correcting data for the eye being examined are computed from the optical characteristics of the adaptive optical elements, as modified. The method not only takes into consideration the aberrations of the optical imaging system but also the properties of reception and signal processing in the human brain. The method is further characterized in that the correction data for the aberrations of the human eye that impair the vision can be obtained by a measuring method that is actively physiologically evaluated beforehand. There is also provided an apparatus for determining vision defects and for collecting data for correcting vision defects.

    摘要: This invention relates to a method and a device for the complete correction of sight defects in the human eye. Combinations of measuring, and processing methods are described which when applied as disclosed in the invention, make it possible to fully correct sight defects in the human eye. Measuring methods are used which can precisely scan the surface of the cornea and also register other imaging defects in the light path up to the retina. Computer-aided of said measuring results determined when combined with calculation of ideally corrected ocular lenses (for example after cataract operations) or ideally corrected surfaces of the cornea opens up the possibility of manufacturing a patient-specific lens and/or achieving ideal correction of the cornea using preferably a topography-supported spot-scanning-excimer laser system.

    摘要: An ophthalmologic laser device includes a pulsed laser configured to produce radiation focused along at treatment beam path. A variably adjustable beam deflector unit and a focusing lens system are disposed in the treatment beam path. The deflector unit is configured to focus the radiation in different target volumes. Measuring equipment is configured to determine a shape and position of optical interfaces along a detection beam path. A control unit is configured to control the laser and the deflector unit and to implement steps including determining a shape and position of an interface of a membrane of a capsular bag of an eye located in a treatment area using the measuring equipment, determining coordinates of a target volume such that, on irradiation of the target volume, a pressure wave runs from the target volume to the anterior or posterior membrane, and adjusting the deflector unit to the target determined volume.
