Abstract

There is provided a system, apparatus and methods for enhancing the illumination of structures of the eye using predetermined scan patterns of an illuminating light beam. The systems, apparatus and methods further provide for obtaining enhanced single images of multiple structures of the eye.

Claims (57)

1. A system for performing laser surgery on a structure of an eye, the system comprising:

a. a digital camera, comprising an image plane;

b. a map defining a relationship between a plurality of points in a three dimensional volume of space and the image plane of the digital camera; wherein the three dimensional volume of space is positioned to contain a structure of the eye;

c. an illumination source for illuminating the structure of the eye in the three dimensional volume of space;

d. a memory, the memory storing the map;

e. a processor;

f. the digital camera, the map and the processor configured to create an enhanced digital single composite image of the structure of the eye;

g. a control system; and,

h. a therapeutic laser shot pattern.

2. The system of claim 1 , wherein the relationship is linear.

3. The system of claim 1 , wherein the relationship is non-linear.

4. The system of claim 1 , wherein the map eliminates image distortion; whereby the enhanced digital composite image is a dimensionally accurate image.

5. The systems of claim 1 or 4 , wherein the structure of the eye is a cornea.

6. The systems of claim 1 or 4 , wherein the structure of the eye is a lens.

7. The systems of claim 1 or 4 , wherein the illumination source is configured to avoid interference from a pupil of the eye.

8. The system of claim 1 , wherein the illumination source is a non-coherent light source.

9. The system of claim 1 , wherein the illumination source comprises a diode.

10. The systems of claim 1 or 4 , wherein the digital camera and processor are configured to create an enhanced digital single composite image of a plurality of structures of the eye.

11. The systems of claim 10 , wherein the structures of the eye are selected from the group consisting of a cornea, a peripheral edge of a cornea, an anterior lens capsule, a posterior lens capsule, and a lens.

12. A system for performing laser surgery on a structure of an eye using an enhanced digital composite image of the eye, the system comprising:

a. a calibrated digital camera, comprising an image plane;

b. the calibrated digital camera configured to create an enhanced digital single composite image of a plurality of structures of an eye, wherein the structures comprise a structure selected from the group consisting of a cornea, a peripheral edge of a cornea, an anterior lens capsule, a posterior lens capsule, and a lens;

c. a map defining a relationship between a plurality of points in a three dimensional volume of space and the image plane of the calibrated digital camera; wherein the three dimensional volume of space is positioned to contain the structures of the eye;

d. an illumination source for illuminating the structures of the eye in the three dimensional volume of space to provide raw images of the structures of the eye;

e. a memory;

f. a processor;

g. the calibrated digital camera, the map, the memory and the processor configured to create an enhanced digital single composite image of the structures of an eye from the raw images;

h. a control system; and,

i. a therapeutic laser shot pattern based upon the enhanced digital single composite image.

13. The system of claim 12 , wherein the enhanced digital single composite image is a dimensionally accurate image.

14. The systems of claim 12 or 13 , wherein the system is configured to create the enhanced digital single composite image without digital alteration or digital enhancement.

15. The system of claim 12 , wherein the relationship is linear.

16. The system of claim 12 , wherein the relationship is non-linear.

17. The system of claim 12 , wherein the illumination source comprises a diode.

18. The systems of claim 12 or 13 , wherein the illumination source comprises a non-coherent light source.

19. The systems of claim 12 or 13 , wherein the illumination source is configured to avoid inference from the pupil.

20. The system of claim 1 , wherein the illumination source is configured to avoid inference from the pupil.

21. A system for performing laser surgery on a structure of an eye using an enhanced digital composite image of the eye, the system comprising:

a. an image capture device;

b. the system configured to create an enhanced digital single composite image of a plurality of structures of an eye, wherein the structures comprise a structure selected from the group consisting of a cornea, a peripheral edge of a cornea, an anterior lens capsule, a posterior lens capsule, and a lens;

c. a map defining a relationship between a plurality of points in a three dimensional volume of space and the image capture device; wherein the three dimensional volume of space is positioned to contain the structures of the eye;

d. an illumination source for illuminating the structures of the eye in the three dimensional volume of space to provide raw images of the structures of the eye;

e. a memory;

f. a processor;

g. the map, the memory and the processor configured to create an enhanced digital single composite image of the structures of an eye from the raw images;

h. a control system; and,

i. a therapeutic laser shot pattern based upon the enhanced digital single composite image.

22. The system of claim 21 , wherein the enhanced digital single composite image is a dimensionally accurate image.

23. The system of claim 21 , wherein the system is configured to create the enhanced digital single composite image without digital alteration or digital enhancement.

24. The system of claim 21 , wherein the relationship is linear.

25. The system of claim 21 , wherein the relationship is non-linear.

26. The system of claim 21 , wherein the illumination source comprises a diode.

27. The system of claim 21 , wherein the illumination source comprises a non-coherent light source.

28. The system of claim 21 , wherein the illumination source is configured to avoid inference from the pupil.

29. The systems of claim 21 , 22 , 23 , or 28 , wherein the image capture device comprises a digital camera.

30. The systems of claim 21 , 22 , 23 , or 28 , wherein the image capture device comprises an image plane.

31. The systems of claim 21 , 22 , 23 , or 28 , wherein the image capture device comprises a digital camera, comprising an image plane.
