shutterstock 1175895889 The team at Shenandoah LASIK & Cataract Center treats each patient according to their unique needs and preferences. We take great care with each case to achieve optimal outcomes. Our patients know that they can count on us to provide the fullest extent of information regarding their procedure and anticipated side effects. With this in mind, we will discuss the issue of halos and glare after LASIK surgery and what patients may do if they encounter them.

About Glare and Halos

Glare and halos are visual aberrations that occur around sources of light. When a person looks at lights, especially at night, they may notice a strange glow around them. This glow may also appear around brightly-colored objects or shiny objects. Glare and halos tend to be relatively common after LASIK surgery. They are among the most common side effects associated with this procedure. Knowing this, patients can navigate their postoperative experience with a little more peace of mind.

Why Do These Vision Issues Occur?

The LASIK procedure involves the creation of a flap in the outermost aspect of the cornea known as the epithelium. The flap is lifted up so that the surgeon can adjust the contour of the cornea itself using a surgical laser. The flap is applied back over the cornea after this adjustment, and heals nicely over time. Because the shape of the cornea is different after surgery, it can take days or weeks for the eyes to adjust to the way that light now passes through the cornea to the retina at the back of the eye. As a result, glare and halos may occur.  

Side effects like glare and halos generally subside over two to three weeks. However, they can last a month or more. Glare and halos are usually most pronounced during the first week after LASIK. After that time, they increasingly lessen to a point at which they are simply no longer noticeable. 

Can I do Anything about Glare and Halos after LASIK?

It may not be possible to prevent the side effects associated with LASIK surgery. However, they may be diminished in intensity. The best way to do this is to strictly follow the doctor’s postoperative instructions regarding caring for the eyes, including avoiding certain activities if advised to do so. If questions arise or glare and halos don’t seem to be getting better, bring this up at your follow-up visit.
