Abstract

The disclosure relates to systems and methods for performing eye surgery in which a single image that simultaneously presents a graphical representation of a planned or actual flap location superimposed with a graphical representation of a planned or actual area of ablation is used.

Claims (31)

1. A surgery system for performing eye surgery comprising:

a cutting device comprising a laser configured to cut a flap in a cornea of an eye undergoing eye surgery;

a shaping device comprising a laser configured to perform ablation of an interior part of the cornea;

at least one display configured to:

display a single image that simultaneously presents a graphical representation of a planned or actual flap location superimposed with a graphical representation of a planned area of ablation, the single image showing the planned flap location relative to the planned area of ablation, the graphical representation of the planned flap location associated with a plurality of flap parameters, the graphical representation of the planned area of ablation associated with a plurality of ablation parameters, the planned area of ablation comprising a plurality of ablation locations, the graphical representation of the planned area of ablation comprising a heat map of the planned area of ablation that represents each ablation location with a different color; and

a computer configured to:

receive an adjustment of the flap parameters;

adjust the planned flap location relative to the planned area of ablation shown in the single image by adjusting the graphical representation of the planned flap location according to the adjusted flap parameters;

receive an adjustment of the ablation parameters; and

adjust the planned area of ablation relative to the planned flap location shown in the single image by adjusting the map of the planned area of ablation according to the adjusted ablation parameters.

2. The system of claim 1 , wherein the single image further comprises textual information regarding the flap.

3. The system of claim 2 , wherein the textual information regarding the flap comprises textual information regarding at least one of the side angle of the cut, flap diameter, flap thickness, hinge size, or hinge location.

4. The system of claim 1 , wherein the single image further comprises textual information regarding the ablation.

5. The system of claim 4 , wherein the textual information regarding the ablation comprises textual information regarding at least one of sphere, cylinder, or axis.

6. The system of claim 1 wherein the plurality of ablation parameters comprise a size of the planned area of ablation.

7. The system of claim 6 wherein the size of the planned area of ablation is presented as a planned optical zone and a planned ablation zone.

8. The system of claim 1 , wherein the laser configured to cut the flap comprises a femtosecond laser.

9. The system of claim 1 , wherein the laser configured to perform ablation comprises an excimer laser.

10. The system of claim 1 , wherein the single image simultaneously presents a graphical representation of an actual flap location superimposed with the graphical representation of the planned flap location and the graphical representation of the planned area of ablation.

11. The system of claim 1 , wherein the single image simultaneously presents a graphical representation of an actual ablation area superimposed with the graphical representation of the planned flap location and the graphical representation of the planned area of ablation.

12. The system of claim 1 , wherein the single image simultaneously presents a graphical representation of an actual flap location and an actual ablation location superimposed with the graphical representation of the planned flap location and the graphical representation of the planned area of ablation.

13. The system of claim 1 , wherein the image further presents graphical information regarding the optical zone, the location or size of the pupil, or the location or size of the iris.

14. The system of claim 1 , wherein the at least one display comprises at least one cutting device display and at least one separate shaping device display, and the single image is displayed on one or both of the at least one cutting device display and the at least one separate shaping device display.

15. The system of claim 1 , wherein the image comprises an alert if a potential inconsistency between the planned or actual flap location and the planned or actual area of ablation is identified by the system.

16. The system of claim 1 wherein the graphical representation of the planned or actual flap location further comprises a perimeter of the planned or actual flap.

17. The system of claim 1 wherein the single image further comprises sphere, cylinder, and axis parameters.

18. The system of claim 1 wherein the graphical representation of the planned or actual area of ablation further comprises a size of a planned optical zone and a size of a planned ablation zone.

19. The system of claim 1 wherein the at least one display is configured to:

overlay a video of the eye undergoing eye surgery onto the single image.

20. The system of claim 1 wherein the laser configured to cut the flap and the laser configured to perform ablation is the same laser.

21. The system of claim 1 wherein the laser configured to cut the flap and the laser configured to perform ablation are different lasers.
