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.

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.
