LASIK eye surgery is a procedure that makes permanent changes to the cornea. The cornea is the clear covering on the eye. By using a laser, this procedure helps people who are nearsighted, farsighted or have astigmatism. A common symptom of LASIK eye surgery is severe dry eyes. Though most of the time the symptom will come and go after a few weeks. For some cases, it's more serious and may affect your vision after LASIK surgery.
