Abstract

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.

Claims (26)

1. A navigation apparatus for detecting structures within an eye and for processing the eye as a function of the detected structures, the navigation apparatus comprising:

a detection device configured to acquire geometric data of an optical element of the eye;

a processing device comprising a laser; and

a controller to which the detection device and the processing device are connected,

wherein the detection device is further configured to transfer the acquired geometric data to the controller, and

wherein the controller is configured to use the acquired geometric data to calculate target coordinates for the processing device.

2. The navigation apparatus of claim 1 , wherein the detection device comprises one of an optical confocal device or an optical coherence tomography device.

3. The navigation apparatus of claim 1 , wherein the detection device comprises a polarization optical sensor system.

4. The navigation apparatus of claim 1 , wherein the detection device includes a dynamic wavefront diagnosis device configured to measure a range of accommodation of the optical element during at least one of positive accommodation or negative accommodation.

5. The navigation apparatus of claim 4 , wherein the dynamic wavefront diagnosis device is further configured to measure a speed at which the range of accommodation of the optical element is traversed by the optical element.

6. The navigation apparatus of claim 1 , wherein the detection device is configured to acquire geometric data of an eye by using at least one of an optical coherence tomography device, a rotating slit Scheimpflug camera, a confocal laser scanner, or an ultrasonograph.

7. The navigation apparatus of claim 1 , wherein the controller is configured to calculate target coordinates for the processing device using a finite element method.

8. The navigation apparatus of claim 1 , wherein the controller is configured to calculate target coordinates for the processing device so as to determine preferred cutting geometries that will at least one of:

increase an accommodative ability of the eye when applied to the eye, or

be used during one of refractive laser surgery or cataract surgery.

9. The navigation apparatus of claim 1 , wherein the laser is an ultra-short pulsed laser system.

10. The navigation apparatus of claim 9 , wherein the ultra-short pulsed laser system is configured to produce bubble fields in the eye.

11. The navigation apparatus of claim 1 , further comprising an ophthalmologic irrigation device having at least one cannula,

wherein the at least one cannula is configured to remove a fragmented nucleus from the eye.

12. The navigation apparatus of claim 11 , wherein the at least one cannula is further configured to fill a hollow lens body with a gel material.

13. The navigation apparatus of claim 1 , wherein the optical element has a different refractive index than a medium that surrounds the optical element.

14. The navigation apparatus of claim 13 , wherein the optical element has a refractive index that is greater than that of a medium that surrounds the optical element.

15. The navigation apparatus of claim 1 , wherein the optical element is a lens of the eye.

16. The navigation apparatus of claim 15 , wherein the detection device is further configured to detect an inner structure of the lens of the eye.

17. The navigation apparatus of claim 16 , wherein the detection device is further configured to obtain a three-dimensional image of the inner structure of the lens of the eye.

18. The navigation apparatus of claim 1 , wherein the detection device is further configured to detect visual defects, a topography of the cornea of the eye, and/or a pupil size of the eye.
