An ophthalmoscope having a laser device for laser irradiation of an eye, in particular for performing a photocoagulation on fundus of the eye of the eye, includes an illuminator for illuminating the eye as well as a camera for acquiring an image of the eye. The illuminator is adapted to generate visible and infrared lights. The ophthalmoscope further includes a control unit adapted to trigger the illuminator for generating a light pulse of visible light and to read out from the camera a control image of the eye acquired by the camera during the light pulse. The ophthalmoscope is configurable to acquire an image of an eye and perform a laser treatment of an eye.

Ophthalmoscope having a laser device

An ophthalmoscope for observing an eye comprises a converging first lens system for generating a real intermediate image of a region in the eye in an intermediate image plane as well as an observation apparatus having an imaging optics for imaging the real intermediate image in an imaging plane in the observation apparatus and for imaging an aperture of the observation apparatus in a pupil of the eye. Between the first lens system and the imaging optics of the observation apparatus, a diverging second lens system is provided for enlarging a working distance between the first lens system and the pupil and for enlarging a field angle.

Ophthalmoscope for observing an eye

An ophthalmic apparatus including an observation system configured for displaying a moving image of a patient's eye, an optical system for directing an illumination beam into the patient's eye and for directing an observation beam from the patient's eye into the observation system, a control system configured for controlling the optical system, and a control stick for inputting control signals into the control system including an auxiliary control element being provided on the control stick for inputting auxiliary control signals into the control system, wherein the control system is configured for controlling a display mode of displaying the moving image of the observation system according to the auxiliary control signals. The invention further relates to a method of operating said ophthalmic apparatus.

Ophthalmic apparatus and method of operating the same

An ophthalmoscope includes a therapy beam source configured to apply therapy beam pulses onto an eye and a drive unit configured to store information about the therapy beam pulses applied onto the eye.

Ophthalmoscope including therapy beam pulse information storage

An ophthalmoscope comprising includes a display, a therapy beam source, and a drive unit. The display is configured to display a live image of a patient's eye. The therapy beam source is configured to apply therapy beam pulses onto the eye. The drive unit is configured to superimpose onto the live image of the eye target positions intended for the application of therapy beam pulses.

Ophthalmoscope including therapy beam targeting

An ophthalmoscope includes a display, a therapy beam source, and a drive unit. The display is configured to display a live image of a patient's eye. The therapy beam source is configured to apply therapy beam pulses onto the eye. The drive unit is configured to superimpose onto the live image of the eye a virtual pattern of positions intended for the application of therapy beam pulses.

Ophthalmoscope including virtual position patterning for therapy beam application

An opthalmoscope for examining a patient's eye includes an illumination device for generating an illumination beam Illumination imaging optics image the illumination beam onto the eye and a scanning device scans the illumination beam over the eye. The opthalmoscope also includes an observation device and observation imaging optics for imaging an observation beam generated by reflection of the illumination beam from the eye onto the observation device. An electronic shutter excludes stray light from the observation beam. The observation device comprises an electronic sensor with an array of photosensitive pixels that can respectively be activated and/or read out in rows, and the scanning device includes an electronic drive circuit for reading out at least one pixel row of the sensor.
