LASIK works by permanently reshaping the front of your eyes, and that change cannot wear off. However, some eyes will regress over time and may need an enhancement or touch up with the laser. This is more common with larger starting visual errors that require more reshaping of the eye. Also, as we age, normal changes in our vision often occur, and LASIK does not stop these from happening. For most, LASIK can last ten years or longer, but everyone’s a little different.
