Abstrakt: A gaussian beam from a CO_2 laser emitting at 10.6 μ was used to measure damage thresholds on rabbit cornea at exposure times of 55 msec, 10 msec, and 3.5 msec. A theoretical model of the radiation–tissue interaction is presented and compared with experimental data. The comparison suggests that a critical temperature exists above which lesions are caused by protein denaturation. The model is useful for establishing safe exposure levels within a limited exposure range.
