Abstract:
Excimer laser was found in 1975, and has been used in corneal refractive surgery, which made a great progress and become rapidly developed. ArF laser of 193 nm has high accuracy because it can gasify corneal tissue molecule. Moreover, it does not produce heat effect on tissues surrounding irradiated sites, so not produce adverse effect on corneal structure. At present, excimer laser has been successfully used in corneal radial incision, excimer laser corneal refractive surgery, laser in situ keratomileusis, laser epithelial keratomileusis and laser subepithelial keratomileusis. With increasing understanding of excimer laser and accumulating clinical experience, novel, accurate and predictive excimer laser corneal refractive surgery will be developed.
