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 method for enhancing an illumination of structures of an eye and imaging the structures, the method comprising:
a) selecting a first predetermined illumination scan pattern, having a predetermined rate and area;
b) selecting a second predetermined illumination scan pattern, having a predetermined rate and area; wherein either the second scan area is different from the first scan area, or the second scan area and the second scan rate are different from the first scan area and the first scan rate;
c) directing a first illuminating beam of light in the first scan pattern toward a first structure of the eye whereby a first illuminated image is created;
d) directing a second illuminating beam of light in the second scan pattern toward a second structure of the eye, wherein the second structure is different from the first, whereby a second illumination image is created;
e) digitally capturing the first illumination image on a first predetermined portion of an image capture device;
f) digitally capturing the second illumination image on a second predetermined portion of the same image capture device, wherein the second portion is different than the first portion;
g) whereby a single composite image of the illuminated components is created on the image capture device by combining the digitally captured first and second illumination images.
2. The method of claim 1 , wherein at least one of the predetermined illumination scan patterns is optimized for the component to be scanned.
3. The method of claim 1 , wherein the first structure of the eye is the cornea of the eye.
4. The method of claims, 1 , wherein the second structure of the eye is the natural crystalline lens of the eye.
5. The method of claim 3 , wherein the second structure is the natural crystalline lens of the eye.
6. A system for providing enhanced illumination of structures of the eye and imaging the structures, the system comprising:
a) an illumination light source for providing an illumination light beam;
b) a control system, associated with the illumination light source; the control system configured to control the illumination light source so that the following patterns are generated:
i) a first predetermined illumination light pattern,
having a predetermined rate and area;
ii) a second predetermined illumination light pattern, having a predetermined rate and area; wherein either the second scan area is different from the first scan area, or the second scan area and the second scan rate are different from the first scan area and the first scan rate; and the system further comprising:
c) an image capture device comprising:
i) a first means for digitally capturing a first image of a first area of the eye generated by the first illuminating light beam scan pattern; and
ii) a second means for digitally capturing a second image of second area of the eye, wherein the second area is different from the first area, generated by the second illuminating light beam scan pattern; and,
iii) wherein the first means for digitally capturing the first image and the second means for capturing the second image are different portions of the same image capture device; and
d.) wherein the system is configured to create a single composite image of the illuminated components on the image capture device by combining the digitally captured first and second images.
7. The system of claim 6 , wherein the illumination light beam is an illumination laser beam.
