Corneal Damage from Infrared Radiation.

Abstract

This report summarizes research during the past year on: the damage mechanism for short (80 ns) pulses of CO2 laser radiation interacting with the cornea epithelium; epithelial damage from multiple-pulse exposures to more penetrating mid-infrared radiation from a Tm:YAG laser at 2.02 micro; and predictions of retinal damage thresholds for exposures to sources with rectangular irradiance distributions. Damage threshold measurements on corneas maintained at 21 C using single 80 ns pulses continue to support a thermal damage mechanism.
