Variable Spot Scanning and Wavefront-Guided Laser Vision Correction

The excimer laser is a remarkable tool. It emits an invisible burst of light one hundred thousand times more intense than the noonday sun that lasts just billionths of a second. When that light reaches the cornea of a human eye, it etches away a few millionths of an inch of cornea and propels the ejected material outward at supersonic speeds. One engineer likened it to performing eye surgery with a light saber.
