Also called as Bladefree Lasik has raised safety to a whole new level, because the flap is no longer required to be made with a mechanical razor (blade), as was the case in the earlier technology represented by LASIK operations.
LASIK surgery cannot treat presbyopia per se. However, monovision through LASIK is a popular option. In monovision, one eye is fully corrected for distance vision whilst the other eye for reading, is under-corrected with residual myopia, in order to offset presbyopia.
