Does LASIK surgery last forever?

Together with the lens, the cornea refracts light allowing a person to see. If there are defects in the cornea (e.g. it is irregularly shaped) there can be refractive errors and vision problems.[1] About 120 million people in the United States wear eyeglasses or contact lenses to correct the refractive errors that lead to nearsightedness, farsightedness, or astigmatism.[2]

Laser eye surgery improves 'natural' eyesight by altering the shape of the cornea. In many cases it will allow people to see with 20:20 vision without glasses or contact lenses. As people age the lens in their eye loses its elasticity and ability to focus on objects.[3] This is called presbyopia and is most common after the mid-40s. People who have LASIK surgery can still experience presbyopia later on in life. This means that even after the surgery, people will likely need reading glasses later on in life.[4] 

If you do get presbyopia, LASIK surgery may help to correct distant vision, but can worsen near vision. To accommodate this, some people will have one eye's vision corrected for near vision and the other corrected for distant vision - this is called 'monovision'.[5] Not everyone is able to adjust to or tolerate monovision, however, so it's best to do a trial with contact lenses before having a permanent surgical procedure.[5]

So in short, yes it works but your vision will likely become impaired as you get older.
