Most patients are extremely pleased with the results of their refractive surgery and the freedom from their glasses or contact lenses. Refractive surgery is the most common elective surgical procedure performed worldwide.

However, just as any other surgical procedure, refractive surgery may be associated with intraoperative and postoperative complications. These include vision problems such as ghosting, halos, starbursts, night vision symptoms, double-vision, dry-eye syndrome, over- or under-correction, irregular flaps, epithelial ingrowth or infection.

The incidence of severe, vision-threatening complications is less than 1%. Not all patients experience all symptoms, and some patients with these complications experience no symptoms and require no treatment.

Treatments for the above risk may include glasses, contact lenses, re-treatment with laser, medicated or lubricating eye drops, oral medications and/or surgical correction.

Your optometrist should perform a thorough eye exam and discuss whether you are a good candidate. During your consultation at Horizon you will be informed about the risks, benefits, or alternatives to the surgery are. You will be given a full, informed consent to read and sign prior to surgery.

In October 2009, the FDA, the National Eye Institute (NEI), and the Department of Defense (DoD) launched the LASIK Quality of Life Collaboration Project (LQOLCP) to help better understand the potential risk of severe problems that can result from LASIK. The project aimed to determine the percent of patients who develop difficulties performing their usual activities following LASIK, and to identify predictors for those patients.
