Infrared radiation from a CO2 laser at a wavelength of 10.6 μm is strongly absorbed by the cornea. Indeed, 99% is absorbed within the first 50 μm of tear film and epithelium. This energy is rapidly converted to heat that initially is concentrated in the volume of absorption and subsequently is conducted to deeper layers of the cornea and beyond. Consequently, various layers of the cornea can sustain thermal damage, depending on the exposure conditions. In this review the authors summarize very briefly our past work on: epithelial damage thresholds for single- and multiple-pulse exposures having individual pulse durations between 1 ms and 10 s; endothelial damage thresholds and endothelial temperature histories; and damage thresholds for stromal cells.
