The big benefit of LASIK is that it\u2019s a highly accurate procedure that can correct a wide range of refractive or focusing problems and it can be done painlessly, safely, and the recovery is very rapid.1 Healing takes place within three hours and vision recovery occurs overnight. The disadvantage of laser done with LASIK is the flap. The reason why that can be a disadvantage in a very small number of people is that the flap could potentially be injured if you had a job that involved, for example, being in the military or being in the emergency services, or if you were someone that was highly involved in contact sports. In that case, LASIK may not be the best treatment for you. You may be a better candidate for having a surface laser.
