Claim 9:
10. A method for quantifying retinal traction on a retina of a patient eye during an ophthalmic procedure, the method comprising:
receiving, via an electronic control unit (ECU), stereo image data of the retina from a stereo camera during the ophthalmic procedure, wherein the stereo image data includes stereo image pairs;
assigning tracking points as coinciding pixels of the stereo image pairs;
automatically performing a digital image correlation (DIC) process, via the ECU, using the stereo image pairs to thereby ascertain relative motion of the tracking points;
associate relative motion of the tracking points with the retinal traction, using a traction map of the ECU, to thereby determine a numeric traction quotient indicative of magnitude of the retinal traction; and
executing a control action via the ECU using an indicator device, based on the numeric traction quotient, wherein the control action is indicative of the retinal traction.
