Laser corneal refractive surgery is the method for refractive error correction, with wide clinical applications. In a history of more than 20 years, more options for safer surgery have gradually become available, from photorefractive keratectomy (PRK), laser in situ keratomileusis(LASIK) and sub-Bowman′s keratomileusis (SBK), to more recent procedures by the ″knife″ to ″femtosecond″ transformation, femtosecond laser assisted-LASIK, small incision lenticule exeraction. More attention is now focused on corneal biomechanical stability. This is especially true for excimer laser TransPRK, which is gradually replacing LASEK. There are now good clinical results with more precise, focused and personalized techniques. Post-operative focus used to be mainly on the problem of corneal structure, complications and visual acuity. Recently there has been greater focus on monocular corneal aberrations, topographic maps and the relationship between binocular vision, personalized visual requirements and long-term stability of the corneal structure. This shift in focus has even included the psychological and spiritual needs of the patients.
