1. A system for photoaltering a region of an eye, the system comprising:
- a laser assembly that outputs a non-ultraviolet, ultrashort pulsed laser beam;
a controller coupled to the laser assembly programmed to perform operations of directing the laser assembly to output the pulsed laser beam to the region of the eye;
an imaging system to which the controller is coupled, comprising;
an image sensor capturing a high resolution first real-time digital image of the eye having a first resolution and a frame rate of at least about 20 frames per second; and
an imaging system monitor displaying a second real-time digital image of the eye based on the high resolution first real-time digital image of the eye, the second real-time digital image having a second resolution that is less than the first resolution, wherein the controller produces the second real-time digital image of the eye via a compression of the first real-time digital image of the eye and outputs the second real-time digital image of the eye to the imaging system monitor to be continuously displayed; and
a user interface to which the controller is coupled, the user interface having a touch-sensitive monitor for displaying digital video received from the controller, and a plurality of laser operating parameters and controls, wherein the touch-sensitive monitor of the user interface and the imaging system monitor are separate monitors for displaying respective images,wherein the controller is further programmed to produce a third real-time digital image of the eye selected from either the first real-time digital image of the eye or the second real-time digital image of the eye and output the third real-time digital image of the eye to and display it on the touch-sensitive monitor of the user interface, and respond to operator input of the laser operating controls after display of the third real-time digital image of the eye.

Abstract
System and method of photoaltering a region of an eye using a high resolution digital image of the eye. The system includes a laser assembly for outputting a pulsed laser beam, an imaging system for capturing a real-time high resolution digital image of the eye and displaying the digital image of the eye, a user interface receiving at least one laser parameter input, and a controller coupled to the laser assembly, imaging system, and user interface. The controller directs the laser assembly to output the pulsed laser beam to the region of the eye based on the laser parameter input.
