    • Abstract
  • In order to increase the precision and safety of the corneal ablation refractive surgery,two mathematical models for corneal ablation were given,one was for spherical myopia and compound myopic astigmatism,the other was for spherical hyperopia and compound hyperopic astigmatism,Based on both the mathematical models,the flying-spot scanning algorithm was put forward.The mathematical models and the algorithm were applied to ophthalmic excimer laser system.Eighty-nine eyes underwent laser in situ keratomileusis(LASIK) using the models and algorithm,including 88 eyes with spherical myopia and compound myopic astigmatism and 1 with compound hyperopic astigmatism.The lightsight of 80.7% of the nake eyes increased upto 0.8.It can be concluded that the mathematical models and the algorithm are precise and safe and the laser cornea surgery is satisfactory.
