Abstract

A device for superimposing parameters and/or image data in the stereoscopic observation path of ophthalmological devices relates to an apparatus for reflecting relevant parameters and/or image data into the stereoscopic observation beam path of ophthalmic devices, for example for therapeutic laser treatments of an eye. The device includes an additional micro-display, which is connected to the control unit, and a beam deflection element for reflecting the parameters and/or image data shown on the micro-display into the stereoscopic observation beam path, which are for example arranged in the parallel beam path. Even though the apparatus is intended for ophthalmic devices for therapeutic laser treatment in the eye, it can also be used, in principle, for ophthalmic devices for examination, diagnosis and surgical interventions.

First claim

1 .- 17 . (canceled)

18 . An apparatus for reflecting relevant parameters and/or image data into the stereoscopic observation beam path of ophthalmic devices, comprising:
a first micro-display, which is connected to a control unit, and a first beam deflection element that reflects parameters and/or image data shown on the micro-display into the stereoscopic observation beam path.

19 . The apparatus as claimed in claim 18 , wherein the micro-display and the beam deflection element are arranged in a parallel beam path.

20 . The apparatus as claimed in claim 18 , wherein the micro-display is self-illuminating.

21 . The apparatus as claimed in claims 18 , wherein the micro-display has an image diagonal of less than 1″.

22 . The apparatus as claimed in claims 21 , wherein the micro-display has an image diagonal of less than 0.5″.

23 . The apparatus as claimed in claims 21 , wherein the micro-display has an image diagonal of less than 0.4″.

24 . The apparatus as claimed in claim 18 , wherein the micro-display has a refresh rate selected from a group consisting of at least 24 frames per second, more than 50 frames per second and more than 100 frames per second at a resolution of about 1024×768.

25 . The apparatus as claimed in claim 18 , wherein the beam deflection element further comprises a semi-transparent mirror or folding mirror or a prism.

26 . The apparatus as claimed in claim 18 , wherein the beam deflection element that reflects the parameters and/or image data shown on the micro-display into the right or left beam path of the stereoscopic observation beam path is arranged in displaceable fashion.

27 . The apparatus as claimed in claim 18 , further comprising a second micro-display and a second beam deflection element that with the first micro-display and the first beam deflection element represent and reflect three-dimensional image data.

28 . The apparatus as claimed in claim 18 , wherein the control unit and operating elements are embodied to modify and activate displayed laser parameters or to select and modify the image data.

29 . The apparatus as claimed in claim 18 , wherein the ophthalmic device comprises a laser slit lamp and operating elements are arranged at the laser slit lamp by application of a multifunctional joystick, an additional rocker or other adjusting elements that are embodied to modify and activate the displayed laser parameters or to select and modify the image data.

30 . The apparatus as claimed in claim 18 , wherein the control unit is structured to actuate the micro-display accordingly to display parameters and/or image data.

31 . The apparatus as claimed in claim 18 , wherein the control unit is structured to vary, on the basis of a live image of an eye, color, contrast and brightness of the parameters and/or image data represented by the micro-display.

32 . The apparatus as claimed in claim 18 , wherein the control unit is structured to mask or switch off a live image of an eye.

33 . The apparatus as claimed in claim 18 , further comprising an imaging unit and an angle mirror or prism arranged between the first beam deflection element which is displaceable and the micro-display.

34 . The apparatus as claimed in claim 18 , further comprising a camera connected to the control unit that enables evaluating a live image of the eye and detecting a focusing state.

35 . The apparatus as claimed in claim 18 , wherein the first beam deflection element is arranged such that the parameters and/or image data shown on the micro-display are reflected into the stereoscopic observation beam path in a direction of an operator.

36 . The apparatus as claimed in claim 18 , wherein the beam first deflection element is structured such that the beam first deflection element can be folded, rotated or displaced by 90° to reflect symbols, structures and/or the image data shown on the micro-display into the stereoscopic observation beam path in a direction of a patient.
