Arrangement and method for carrying out a surgical treatment of an eye
An arrangement for carrying out a surgical treatment of an eye includes a diagnostic instrument which is adapted to register eye-structure data. A data processing unit is adapted to generate, on the basis of the eye-structure data registered by the diagnostic instrument, a structural image that contains at least one mapping of a characteristic eye structure and also at least one positional marking arranged relative to the mapping of the characteristic eye structure. An image-data fade-in device is adapted to fade the structural image generated by the data processing unit into an image generated by a surgical microscope during the implementation of a surgical treatment of the eye.
1. The arrangement for carrying out a surgical treatment of an eye, comprising:
a diagnostic instrument adapted to register eye-structure data,
a data processing unit adapted to generate, on the basis of the eye-structure data registered by the diagnostic instrument, a structural image that contains at least one mapping of a characteristic eye structure and also at least one positional marking arranged relative to the mapping of the characteristic eye structure, the structural image comprising, as the mapping of the characteristic eye structure, a mapping of at least one of a blood vessel, an iris structure, an iris margin, and a limbic geometry against a transparent background, and
an image-data fade-in device which is adapted to fade the structural image generated by the data processing unit into an image generated by a surgical microscope during the implementation of a surgical treatment of the eye.
2. The arrangement according to claim 1 ,
wherein the diagnostic instrument is adapted to register, as the eye-structure data, image data pertaining to at least one of blood vessels, iris structures, an iris margin and the limbic geometry.
3. The arrangement according to claim 1 ,
wherein at least one of the diagnostic instrument and the surgical microscope includes a source of green light.
4. The arrangement according to claim 1 ,
wherein the data processing unit is adapted to generate, on the basis of the eye-structure data registered by the diagnostic instrument, a structural image that contains, as the positional marking, a marker designed in the form of at least one of a point, a line or a surface, a grid, and an axis indicating the location of an astigmatism.
5. The arrangement according to claim 1 ,
further comprising a positioning device for positioning the faded-in structural image relative to the image generated by the surgical microscope.
6. The arrangement according to claim 5 ,
further comprising a device for recognising a selected eye structure in the image generated by the surgical microscope, wherein the positioning device is adapted to position the faded-in structural image, depending on the recognised selected eye structure, automatically relative to the image generated by the surgical microscope.
7. The arrangement according to claim 1 , further comprising:
a positioning device adapted to size-adapt the faded-in structural image relative to the image generated by the surgical microscope.
8. The arrangement according to claim 1 , further comprising:
a positioning device adapted to displace and/or rotate the faded-in structural image relative to the image generated by the surgical microscope.
9. The arrangement according to claim 1 , the characteristic eye structure comprising at least two of a blood vessel, an iris structure, an iris margin, and a limbic geometry against a transparent background.
10. A method for carrying out a surgical treatment of an eye, comprising:
registering eye-structure data;
generating a structural image on the basis of the registered eye-structure data that contains at least one mapping of a characteristic eye structure and also at least one positional marking arranged relative to the mapping of the characteristic eye structure, the structural image comprising, as the mapping of the characteristic eye structure, a mapping of at least one of a blood vessel, an iris structure, an iris margin, and a limbic geometry against a transparent background; and
fading the structural image into an image generated by a surgical microscope ( 30 ) during the implementation of a surgical treatment of the eye.
11. The method according to claim 10 ,
wherein image data pertaining to at least one of blood vessels, iris structures, an iris margin and the limbic geometry are registered as the eye-structure data.
12. The method according to claim 11 ,
wherein during at least one of the registering of the eye-structure data and the implementation of the surgical treatment of the eye, the eye is irradiated by a source of green light.
13. The method according to claim 10 ,
wherein on the basis of the registered eye-structure data a structural image is generated that contains, as the positional marking, at least one of a marker designed in the form of a point, line or surface, a grid, and an axis indicating the location of an astigmatism.
14. The method according to claim 1 , wherein the faded-in structural image is positioned relative to the image generated by the surgical microscope.
15. The method according to claim 14 ,
wherein a selected eye structure is recognised in the image generated by the surgical microscope, and the faded-in structural image is positioned, depending on the recognised selected eye structure, automatically relative to the image generated by the surgical microscope.
16. The method according to claim 10 , further comprising:
size-adapting the faded-in structural image relative to the image generated by the surgical microscope.
17. The method according to claim 10 , further comprising:
displacing and/or rotating the faded-in structural image relative to the image generated by the surgical microscope.
18. The method according to claim 10 , the characteristic eye structure comprising at least two of a blood vessel, an iris structure, an iris margin, and a limbic geometry against a transparent background.
