LASIK can take a few weeks to adjust your vision and the results are permanent, although the eye prescription can still change over time. The only time a follow-up procedure may be necessary is if eyesight changes slightly with age or the initial correction was not enough. Further adjustments can be made several years after LASIK surgery to correct vision if the vision has shifted.
Patients usually experience a dramatic reduction in the need for glasses after LASIK surgery, and some patients do not need to wear glasses at all. Even though LASIK requires a financial investment upfront, patients experience hundreds of dollars of savings each year because they do not need to update their eyeglass and contact lens prescription.

It is important for you to weigh the benefits and risks before choosing to go ahead with surgery. Though the goal of LASIK surgery is to eliminate your need for glasses or contact lenses as much as possible, in some cases you may benefit from wearing glasses part time or full time after a LASIK procedure. For example, for persistent dry eye problems after LASIK, wearing eyeglasses with photochromic lenses can help relieve photophobia sensitivity to light associated with dry eyes.
For cases of mild residual refractive error that don't warrant additional surgery, wearing corrective eyeglasses for specific visual tasks such as driving at night is a good choice. If you can benefit from glasses after LASIK, choose lenses with anti-reflective coating for the best vision and comfort possible. Also, if you're over age 40, consider progressive lenses to provide enhanced vision for reading as well as sharper distance vision.
