How Dangerous Is Eye Surgery?

Laser-assisted in-situ keratomileusis, or LASIK, eye surgery has some risks, but eight out of 10 people no longer need glasses or contacts for most of their activities, and many report that they are highly satisfied with the results, according to Mayo Clinic. Some health conditions increase the risk of developing complications after surgery.

Health conditions that increase a patient's risk of developing complications include rheumatoid arthritis or other autoimmune disorders, immunodeficiency conditions such as HIV, hormonal changes, and unstable eye conditions. A doctor may not recommend LASIK eye surgery for a patient with eye-related changes, fairly good vision, if the patient's job may be affected by the results of the surgery, or if the patient participates in contact sports, according to Mayo Clinic.

Risks associated with LASIK eye surgery include loss of vision, developing debilitating visual symptoms and severe dry eye syndrome. The patient may experience vision loss that doctors cannot correct with glasses, contacts or another surgery. Debilitating visual symptoms include glares, halos and double vision, and these may seriously affect the patient's ability to see in low-contrast situations or at night. A patient with severe dry eye syndrome experiences intermittent vision blurring because the eye cannot produce enough tears to stay moist, describes the U.S. Food and Drug Administration.
