Paper Abstract

Continuous wave (cw) hydrogen fluoride (HF) chemical laser interactions with human corneal tissue have been studied in order to understand tissue heating phenomenology, effects, and mechanisms under well- characterized laser irradiation conditions. Time-resolved tissue front surface temperature measurements have been obtained during laser irradiation using an optical pyrometer system. Both front surface and in-depth temperature distributions have been calculated by 1D and 2D heat transfer models using realistic tissue optical and thermal properties data for comparison with experiment. The combined experimental/modeling results are useful for developing safe and effective laser microsurgical heating procedures.
