The invention relates to an ocular therapy device having a radiation source emitting UV light and an optical imaging system disposed downstream of the radiation source for imaging a therapy beam coming from the radiation source in an ocular imaging plane, wherein an optical condenser unit is disposed downstream of the radiation source and comprising a diaphragm unit, an optical means for influencing a spatial energy distribution which can be associated with the therapy beam and is oriented along the therapy beam cross-section, and comprising an optical means for influencing a beam form, which can be associated with the therapy beam.

Ocular therapy device

The invention relates to an ophthalmoscope for examining the fundus of an eye of a patient, which comprises at least one illuminating device producing at least one illuminating beam, in addition to an imaging lens system which can be associated with the illuminating device and which images the illuminating beam onto the fundus of the eye of a patient; also comprising an observation device, wherein the imaging lens system images an observation beam onto the fundus of the eye, said observation beam being produced by reflecting the illuminating beam; also comprising a diaphragm arrangement introduced into the illuminating beam and the observation beam, whereby the gap of said diaphragm can be variably modified and synchronized. The invention is characterized in that the imaging lens system is formed in such a manner that an intermediate focal plane is created along the illuminating beam and the observation beam, wherein the fundus of the eye and the illuminating device are imaged, so that the intermediate focal plane is imaged infinitively, and so that the infinitively formed intermediate focal plane is imaged on an image plane of the observing beam, wherein the observation device is arranged.

Ophthalmoscope

The invention is characterised by the provision that in a slit lamp or a slit lamp projector an oblique thin glass flat with a partial reflection of the light is disposed at a defined angle relative to the optical path above the filter assembly between the latter and the &ldquo;slit projector&rdquo; lens (,), and in the configuration with an achromatic doublet lens between the lens assemblies in the parallel optical path, in such a way that as a result one part of the incident rays is incident as deflected light cone on a detector assembly which is arranged laterally in the housing at an angle dependent on the angle of the thin glass flat in the housing, which detector assembly measures the respectively existing luminous intensity, transmits the detected values to an evaluation and control means which compares the values so received against a predetermined maximum value, calculates the irradiation dose for the phakic or aphakic eye and, when the value is exceeded, signals this situation on an indicating alarm means and/or reduces the luminous intensity automatically to the predetermined maximum value in a controlled manner.

Luminous intensity detection and control system for slit lamps and slit lamp projections

An apparatus for the observation and treatment of the eye with a laser, having an illumination light source, whose light is focussed on the part of the eye to be observed and which preferably contains a laser, a scanning device, which generates a scanning movement of the light of the illumination light source on the background of the eye, a detector device, which receives the reflected light, an evaluation and synchronization unit, which generates from the time-sequential signal output of the detector device a visual representation of the portions of the eye to be treated and shows the visual representation, on a monitor, and a treatment laser device, whose light can be reflected on the part of the eye to be treated. The apparatus provides that a visual representation in which the location or locations to be treated are marked, can be superimposed on the visual representation of the eye at least on the monitor, and a control unit aligns the laser to the marked location.

An endothelium attachment for a slit lamp device with a microscope objective to increase the magnification of the slit lamp microscope which can be attached in front of the slip lamp microscope housing. The attachment includes a beam splitter provided between the microscope objective and the primary objective of the slit lamp microscope, this beam splitter being arranged in the optical axis of the primary objective and deflecting at least a portion of the light reflected by the eye to be examined into at least one ocular beam path of the slit lamp microscope, and that the portion of the light passing through the beam splitter impinges upon a measuring and/or recording unit.

Endothelvorsatz

A contact lens is disclosed, especially for the treatment of the frontal eye sections with a laser, the surface on the eye side of which has a radius adapted to the radius of curvature of the cornea, this contact lens exhibiting a reflective surface for enlarging the field of vision. The contact lens has the following features:
