What Causes Halos Lasik

Lasik is a corrective eye surgery procedure performed by ophthalmologists. The surgery fixes the defective condition of the eyes so that the patient will no longer need to see with the assistance of glasses or contacts. There are some potential side effects to lasik surgery. A halos effect is a side effect that occurs when people see a light surrounding an object. What causes halos lasik is a question many people who are considering lasik surgery may ask.

During lasik surgery, the ophthalmologist corrects any irregularities in the cornea that exist on the eyes. Some patients may experience severe dry eye after surgery. This means the eyes are not able to produce the moisture it needs. This can cause the eyes to feel irritated and it can impair a person's vision. Dry eyes can also cause the halos effect and obstruct a person's vision in other ways. Dry eyes tend to heal over time, but a person can use artificial tears or prescription tears until the condition is healed.

Sometimes the eyes are not able to properly focus on light right after surgery. This leads to the appearance of a halo around objects. The halos effect is common after lasik surgery and normally corrects itself within a few months. The halo appearance around things can occur during daylight, but it can really become exacerbated at night when the eyes are trying to absorb more light to see things clearly.

Inflammation or the accumulation of fluid around the eyes can lead to halos. Even though patients are given antibiotics before surgery to reduce the chance of contracting an infection, it still may occur. The ophthalmologist also assesses the extent of corneal tissue that needs to be removed before the operation, but if a defective portion of the eye was not properly corrected during the surgery, this can also lead to halos.

If what causes halos lasik persists, the patient should consult the ophthalmologist. The ophthalmologist can recommend different treatment options. The cause of the halo will determine if further surgery will be needed to correct the problem. Any person considering lasik should thoroughly review all of the side effects and complications that may accompany the surgery prior to proceeding with the procedure.
