A high-energy "cold" laser that is used in the PRK procedure
to sculpt the central zone, or visual axis, of the cornea to
correct mild to moderate cases of nearsightedness. The laser
emits a pulsating beam of ultraviolet light that ablates, or
vaporizes, the corneal tissue to the degree designated and
guided by a computer within the laser system.
