The VISX Star S4 Excimer laser produces a high-energy, cold, ultraviolet light beam in pulses and delivers the pulses to a surface of the eye’s cornea. These pulses break the bond between molecules and tissue cells so that a controlled amount of tissue can be vaporized away to reshape the cornea. Excimer laser beams do not disturb the underlying eye structures such as iris, lens, and retina. The Excimer laser is computer controlled and programmed to treat each individual eye with a high degree of precision.
