Nomogram for Treatment of Astigmatism With Laser in situ Keratomileusis

PURPOSE: Laser in situ keratomileusis (LASIK) is a mainstay in refractive surgery. Myopes and compound myopic astigmats generally have a good result after LASIK. However, simple myopic astigmats are sometimes not as pleased with their visual outcome. METHODS: We analyzed 40 patients who underwent LASIK with the Nidek EC-5000 excimer laser and the Hansotome microkeratome. The key to successful LASIK in these patients was proper analysis of corneal topography. RESULTS AND CONCLUSION: We found that 37 of the 40 patients studied had an excellent result, but poor topographic interpretation gave a poorer result in the remaining three patients. We discuss how to correctly interpret corneal topography and proper case selection and patient counseling.
