Despite plenty of scientific evidence to the contrary, some LASIK myths just don’t seem to go away. For instance, many people still think that the results produced by this form of laser eye surgery only last for a few years. This is simply not the case. LASIK will permanently correct vision problems that a patient comes in with to have the procedure, including astigmatism, nearsightedness and farsightedness.
Learning more about how LASIK corrects vision may help you put such a rumor to rest. Here are a few facts that can shed light on this matter.
How LASIK Works
The excimer lasers used by an ophthalmologist during the procedure are designed to reshape the cornea itself. This enables light to enter the eye properly and be focused onto the retina. Doing so eliminates the imperfections in your eye that are causing myopia, hyperopia or astigmatism, resulting in clearer vision. In and of itself, reshaping the cornea is a permanent process. Meaning, it is impossible for your eyes to revert to their previous state afterwards.
Still, patients need to understand that LASIK is not a cure-all for all issues with your eyesight. The operation only seeks to correct the vision problems you had when you came in for the treatment. Therefore, it is possible for your prescription to change naturally or you may develop other issues after you’ve had the surgery. A patient’s farsightedness or nearsightedness may begin to progress again, for example. It is worth noting, though, that slight alterations you may experience will never be quite as bad as your condition before the surgery.
What’s more, this doesn’t happen that often and even if it does, patients have a good option for dealing with it, called LASIK enhancement. According to the American Refractive Surgery Council, the LASIK enhancement rate is only at 1 to 2 percent in the first 12 months, and then about 1 percent a year following the surgery.
LASIK enhancement is a follow-up LASIK procedure performed if a patient’s vision changes significantly over time or if you find the original vision correction to be unsatisfactory. Patients need not worry about their wellbeing when undergoing LASIK a second or third time since it is completely safe. Surgeons conduct meticulous evaluations to make sure that you are still a good candidate.
LASIK is indeed a long-term solution for your existing vision correction needs, but it does not prevent changes that naturally occur with age.
