LASIK or any refractive correction surgery (Incidentally even lasers are surgery) are cosmetic procedures. Though lasik or other forms of corneal laser surgery are touted to be the safest, because they remove tissue from the cornea this is far from the truth. Also what is removed cannot be corrected back.

Sadly, after the surgery if you've lost some vision quality once the cornea is healed, there is probably no reversing it. There is a lot of publications and results of studies of lasik that is not revealed to the customers of this cosmetic procedure.

Also it is sad that this business is so lucrative that it is not ethically overseen and self regulated. Even the authorities do not seem to bother to enforce current legislation that is in force on their advertising.
