People who suffer from nearsightedness, farsightedness or an astigmatism may all be good candidates for LASIK surgery, states the Mayo Clinic. This surgery is a type of eye surgery in which the cornea is reshaped to restore a patient's vision and reduce the need to wear corrective eyeglasses.
LASIK surgery is not a good choice for patients who suffer from presbyopia. This condition typically occurs in patients in their early to mid-40s, describes the Mayo Clinic. With presbyopia, patients may have difficulty seeing objects up close. For patients with this condition, LASIK surgery may only be able to correct their distance vision, not their near vision.
LASIK surgery is a relatively safe procedure, but it does come with a few risks, according to the Mayo Clinic. Patients are at risk for under-correction, over-correction or astigmatism if the laser used during the procedure is not properly handled. Patients may also be at risk for developing visual disturbances at night and having poor night vision. Dry eyes and infection are also both risks that patients take when undergoing LASIK surgery.
Patients who are poor candidates for LASIK eye surgery include patients who have autoimmune diseases, who have severe nearsightedness, have unstable vision or who have persistent dry eyes, states the Mayo Clinic. These conditions could increase a patient's risk for developing unwanted complications after surgery.
