How long does it last? Can a patient need glasses after the surgery?
The amount of time a patient can see excellent after the procedure is dependent on the physiology of that patient’s eyes. Many patients see excellent for many years. There isn’t a specified time that the procedure is “supposed to last.” It’s not like buying a product and getting a warranty. And yes, if a patient does have some regression in their eyes, then that patient could need glasses or contact lenses later. Most patients after the age of 40 who have had LASIK typically need reading glasses due to changes within the eye. This is not an indication of the LASIK procedure failing, just a different change occurring.
