Corneal incisions produced with the fourth harmonic (266 nm) of the YAG laser.
The fourth harmonic wavelength (266 nm) of a neodymium YAG laser was used to cut precise grooves on the surface of the human cornea. Well-controlled cuts were made using the laser operating at 1.3 kHz. The width of the grooves was 2-3 micron. The depth could be controlled by varying the amount of laser exposure.
