Patent ID: 7220255

Claim:
A scanning laser device for ophthalmic surgery, the device comprising: a laser source for generating a beam of laser pulses, each pulse having a tissue ablation profile; scanning optics for directing the beam of the laser pulses; a computer device coupled with the optics for directing each laser pulse to a location on the cornea; the computer device comprising one or more digital storage media having embedded therein programming code for programming one or more processors to perform certain operations, including: a first executable program for calculating a pulse deposit pattern by calculating the location of each laser pulse on the tissue based on overlap of the ablation profile, such that upon ablation according to said calculated pulse deposit pattern, a smooth ablated surface is provided on the tissue; and a second executable program for directing each of the lasers pulses to locations on the tissue in accordance with the pulse locations provided by the first executable program; and an eye movement tracking indicator and optics for directing the laser pulses to be deposited to intended locations on a cornea by adjusting one or more optics when the eye moves during the eye surgery, the eye movement tracking indicator and optics comprising: an eye positional indicator; and laser beam deflecting optics for deflecting the laser beam to follow the movement of the eye.
