The LASIK surgery is performed by an ophthalmologist who uses a laser or microkeratome to reshape the eye's cornea in order to improve visual acuity. For most patients, LASIK provides a permanent alternative to eyeglasses or contact lenses.
But thereâs no set age for LASIK. Most providers wonât perform LASIK on those under 18 because eyes tend to keep changing into early adulthood. But laser eye surgery has been performed on children (with severe vision problems) and octogenarians alike. These are outliers to most cases.
