Apparatus for individual therapy planning and positionally accurate modification of an optical element
A navigation apparatus for optically analyzing an inner structure of an optical element and processing that element includes a detection device and a processing device. The detection device has an aperture smaller than 0.25 and the processing device is disposed relative to the analyzed inner structure of the optical element. An apparatus for planning therapy for a human eye includes a dynamic wavefront measurement device for acquiring wavefront data, a diagnostic device for determining geometric parameters of the optical apparatus of the eye, a controller for consistent superposition of the wavefront and geometric data, and an additional controller for planning the most efficient therapeutic laser cutting paths.
1. A navigation apparatus for optically analyzing an inner structure of an optical element and for processing the optical element, the apparatus comprising:
a detection device having an aperture smaller than 0.25; and
a processing device configured to process the inner structure and adapted to be guided along or in a fixed relationship to the inner structure of the optical element.
2. The navigation apparatus as recited in claim 1 , wherein the detection device includes at least one of a confocal detector, a detector based on optical coherence tomography, a rotating slit Scheimpflug camera, a confocal laser scanner, an ultrasonograph, a device for dynamic wavefront diagnosis, a system for dynamic stimulation of the aberrometry, an aberrometer, and a refractometer.
3. The navigation apparatus as recited in claim 1 , wherein the aperture of the detection device is larger than 0.1.
4. The navigation apparatus as recited in claim 3 , wherein the aperture of the detection device is smaller than 0.22 and larger than 0.18.
5. The navigation apparatus as recited in claim 1 , wherein the detection device includes a polarization optical sensor system.
6. The navigation apparatus as recited in claim 1 , wherein the processing device includes a laser configured to make surgical cuts in the optical element.
7. The navigation apparatus as recited in claim 6 , wherein the laser is a fs-laser.
8. The navigation apparatus as recited in claim 7 , wherein the fs-laser produces a scanned, focused, ultra-short pulsed laser beam.
9. The navigation apparatus as recited in claim 1 , wherein the processing device is configured to deliver radiation in the optical element.
10. The navigation apparatus as recited in claim 9 , wherein the radiation includes pulse energies less than or equal to 1 microJ so as to stimulate subdisruptively or greater than 0.1 microJ to perforate disruptively.
11. The navigation apparatus as recited in claim 9 , wherein the radiation creates rows of narrowly spaced, disruptively produced bubbles to cut.
12. The navigation apparatus as recited in claim 1 , wherein the optical element includes a lens.
13. The navigation apparatus as recited in claim 12 , wherein the lens is an aged eye lens.
14. The navigation apparatus as recited in claim 1 , wherein the navigation apparatus includes an ophthalmologic suction/irrigation device having at least one cannula.
