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.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.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.
