System and method of illumination of structures within an eye
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.
1. A system for the controlled illumination and single image creation of multiple structural components of the eye, the system comprising:
an illumination light source capable of providing a first illumination light beam defining a first illumination light ray line, and a second illumination light beam defining a second illumination light ray line;
the first illumination light ray line corresponding to a first area of the eye;
the second illumination light ray line corresponding to a second area of the eye, wherein the first and second areas are different;
wherein the first illumination light ray defines a first illumination beam having illumination properties that are optimal for illuminating the first area of the eye, wherein the second illumination light ray defines a second illumination beam having illumination properties that are optimal for illuminating the second area of the eye, and wherein the first illumination beam illumination properties are different from the second illumination beam illumination properties;
an image capture system having a first image capture area corresponding to the first illumination light ray line and capable of capturing an image of the first area of the eye, and a second image capture area corresponding to the second illumination light ray line and capable of capturing an image of the second area of the eye;
wherein the image capture system is capable of combining the image of the first area and the image of the second area to provide a single composite image of the eye without registration of the image of the first area and the image of the second area.
2. The system of claim 1 , wherein the light source comprises a super luminescent diode.
3. The system of claim 1 , wherein the first light beam comprises a coherent light beam.
4. The system of claim 1 , wherein the light source comprises a non-coherent light source; whereby laser speckle is avoided in the composite image.
5. The system of claim 1 , wherein the first area of the eye corresponds to a first structure of the eye, and the second area of the eye corresponds to a second structure of the eye, whereby the first and second structures are different.
6. The system of claim 5 , wherein the first structure of the eye is the cornea.
7. The system of claim 6 , wherein the second structure of the eye is anterior lens capsule.
8. The system of claim 1 , comprising a calibration system.
9. The systems of claims 1 , 2 , 7 and 8 , wherein the light source and the image capture system define a Scheimpflug configuration.
10. The system of claim 6 , wherein the second structure is the posterior lens capsule.
11. A method of creating a single composite image of multiple structural components of the eye, the method comprising:
providing a first illumination light beam defining a first illumination light ray line, and a second illumination light beam defining a second illumination light ray line;
directing the first illumination light beam along the first ray line to a first area of the eye, whereby the first area is illuminated;
directing the second illumination light beam along the second ray line to a second area of the eye, whereby the second area is illuminated;
capturing an image of the illuminated first area of the eye to provided a first image, and capturing an image of the illuminated second area of the eye to provided a second image, whereby the first and second images are not the same; and,
processing the images to provide a single composite image of the eye without registration of the image of the first area and the image of the second area.
12. The method of claim 11 , wherein the first, the second, or both illumination light beams are a coherent light beam.
13. The method of 11 , wherein the first, the second or both illumination light beams are a non-coherent light beam; whereby laser speckle is avoided in the composite image.
14. The method of claim 11 , wherein the first area of the eye corresponds to a first structure of the eye, and the second area of the eye corresponds to a second structure of the eye, whereby the first and second structures are not the same, and are selected from the group of structures consisting of the cornea, the lens, the anterior lens capsule, and the posterior lens capsule.
15. The method of claim 11 , whereby the first, the second or both captured images are calibrated.
