ABSTRACT:
A laser eye surgery system and method include a laser for producing a laser beam capable of making refractive corrections, an optical system for shaping and conditioning the laser beam, a digital micromirror device (DMD) for reflecting the shaped and conditioned beam toward the eye, and a computer system for controlling the mirrors of the DMD. The computer system and methodology utilize a higher order polynomial equation to generate a smooth refraction correction profile and determines the coefficients for the higher order polynomial equation from preferably first-, second-, or third-order curves based on the correlation between the coefficients and the desired diopter correction.
