Abstract

Projection of visible, non-treatment light onto an eye to illuminate specific areas of the surgical field is disclosed herein. A surgical system may include a surgical console; a microscope communicatively coupled to the surgical console; a camera communicatively coupled to the surgical console; and a projector operable to project light onto an eye. The projector may be communicatively coupled to the surgical console. A method for light projection may include collecting information from an eye using a camera; determining the light projection based, at least in part, on the collected information; and projecting visible, non-treatment light onto the eye using a projector.

Claims (23)

1. A surgical system for projecting illumination onto an eye comprising:

a microscope;

a camera communicatively coupled to a surgical console, the camera operable to collect image data of an eye; and

the surgical console communicatively coupled to the camera, the surgical console operable to receive the image data, the surgical console comprising:

a processor; and

a memory, the memory comprising code executable by the processor and the processor operable to process the image data in a manner defined by the code to identify one or more cannulas inserted into the eye;

a projector communicatively coupled to the surgical console and operable to project visible, non-treatment light onto a surface of an eye, the projected light being in the form of one or more discrete light projections directed to one or more discrete area of the eye surface that encompasses the cannula to the exclusion of the remainder of the eye surface of the eye based on the received image data, wherein projecting visible, non-treatment light onto the one or more discrete locations comprises selectively illuminating each of the one or more cannulas to form a lighted zone at each of the one or more cannulas conforming to a shape of the cannula.

2. The surgical system of claim 1 , wherein the processor is operable to determine the one or more particular locations on the eye based on the received image data.

3. The surgical system of claim 2 , wherein the image data of the eye corresponds to an image viewable through the microscope.

4. The surgical system of claim 1 , wherein the camera is mounted to the microscope, and wherein the projector is mounted to the microscope.

5. The surgical system of claim 1 , wherein the projected light further comprises an incision marker, a toric axis, or a toric axis marker.

6. A method of projecting light onto an eye comprising:

collecting image data of an eye using a camera;

processing the received image data to determine one or more discrete locations on the eye to be illuminated with projected visible, non-treatment light;

projecting visible, non-treatment light onto the one or more discrete locations of the eye to be illuminated, the one or more discrete locations being one or more cannulas disposed in the eye; and

inserting a surgical instrument into at least one of the one or more cannulas while the visible, non-treatment light is being projected

wherein projecting visible, non-treatment light onto the one or more discrete locations comprises selectively illuminating each of the one or more cannulas to form a lighted zone at each of the one or more cannulas, each of the lighted zones conforming to a shape of the cannula.

7. The method of claim 6 , wherein projecting visible, non-treatment light onto the one or more discrete locations of the eye to be illuminated further comprises projecting visible, non-treatment light in an operating room environment.

8. The method of claim 6 , wherein projecting visible, non-treatment light onto the one or more discrete locations of the eye to be illuminated further comprises projecting a ring of the light onto the one or more cannulas.

9. The method of claim 6 , further comprising:

projecting light onto the eye in the forms of one or more incision markers;

forming one or more incisions in the eye according to the one or more incision markers; and

inserting the one or more cannulas into the eye through the one or more incisions.
