The high powered, short pulsed output of the excimer laser has been proposed for use is producing spatially confined tissue, ablation. In vitro studies of ablation of corneal tissue using 193 nm have been previously reported (Trokel, Srinivasan, Braren, 1983). The excimer laser may be useful in producing incisions in the cornea which alter the topography, thereby modifying the optical power of the cornea. The laser may therefore be applied therapeutically to the correction of myopia and astigmatism (that is, in refractive surgery of the eye).
