What Are the Long-Term Side Effects of Laser Eye Surgery?
Laser eye surgery is a corrective procedure that removes the corneal tissue of the eye with a laser. The laser reshapes the cornea and enhances its focusing power. Though effective for many patients, the FDA warns of potential risks related to laser eye surgery.-
Vision Loss
-
The FDA website reports patients have suffered irreversible loss in lines of vision after laser surgery that cannot be corrected from glasses or contact lenses.
Dry Eyes
-
Surgery may affect tear production in the eye. This causes not only discomfort, but also blurred vision. This could last briefly after surgery but can often remain permanent according to the FDA.
Debilitating Visual Symptoms
-
The FDA reports double vision, glare and halos are all possible side effects that can negatively affect vision, particularly at night or in areas with low lighting.
Decreased Vision Over Time
-
Some farsighted patients have experienced decreased vision as they age, with the vision loss increasing as time passes according to the FDA.
Unknown Other Effects
-
There have been no long-term studies conducted regarding safety of laser eye surgery because the first approved surgery took place in 1998. As patients age, it is possible that they are yet to see additional debilitating vision effects. The FDA suggests one carefully weighs out the pros and cons of laser eye treatment before committing to the surgery.
