Lasik surgery is a procedure that involves correcting vision problems by reshaping the cornea. It is designed to correct nearsightedness, farsightedness and astigmatism. In most cases, this surgery eliminates a person’s need to wear glasses or contacts. However, it is important to note that it has its risks just like any other procedure. Below are some of the risks that are associated with Lasik surgery:

Dry Eyes

This is one of the most commonly reported side effects of Lasik surgery. Dry eyes occur when the eyes are unable to produce enough tears. Dry eyes can cause blurred vision, infection and inflammation. Most patients develop dry eyes a few days after their surgery. This problem can very easily be corrected with artificial tear drops. In rare cases, surgery will be needed to plug the tear ducts.


Infection is a risk that is associated with just about any type of surgery. However, only a small percentage of patients suffer an infection after getting Lasik surgery. Doctors have found that people who wear contacts are at a greater risk for suffering an infection after this procedure. Pain in the eye, increased sensitivity to light, yellow discharge from the eyes, fever and blurred vision are some of the signs of infection.

Even though the risk of infection is small, patients who think that they have an infection need to see their eye doctor as soon as possible. Severe infections can result in permanent vision loss. Anti-inflammatory drops and oral antibiotics can be used to treat an infection.

Reduced Night Vision

Lasik Surgery could possibly reduce a person’s ability to see while driving at night. Some patients also report that they see halos.


Even though Lasik eye surgery can correct astigmatism, it can also cause this problem. If astigmatism occurs, then the patient will most likely need to get a second surgery.

Epithelial Ingrowth

The epithelial cells normally cover the cornea’s surface. Epithelial ingrowth occurs when the cells grow beneath the flap inside of the cornea’s surface. In most cases, this problem does not affect vision and does not require any further treatment.

However, the doctor may choose to prescribe eyedrops. Surgery may be required in some cases. In rare cases, this condition has caused vision loss.


Keratectasia is a condition that occurs when too much corneal tissue is removed or the flap of the cornea is cut too deeply. This condition weakens the cornea, and in most cases, it cannot be corrected with surgery. Keratectasia can cause distorted vision. Patients who have this condition may be prescribed contact lenses in order to hold the cornea in place.

Complications from Lasik surgery are rare, and only occur in about one percent of surgeries. Your doctor will decide whether the benefits of surgery outweigh the potential complications.
