Halo and Glow After LASIK – Reasons, Remedies, and When to Call A Doctor

Las Vegas eye patient experiencing halo and glow after LASIK surgery

So, you’ve just come from your LASIK eye surgery appointment and are ecstatic to be on the mend with brand-new vision. In being free of the hassle that comes with contact lenses and prescription eyeglasses, there are so many activities you’ll be able to participate in without stress like playing contact sports, swimming, or simply enjoying a clear view. As exciting as this is, it’s normal to worry about possible visual disturbances during your recovery, as LASIK halos, glowing lights, glare, and starbursts are all common after effects. As your eyes heal, these visual phenomena may pop up around bright lights or in low light conditions. While this can be alarming, these symptoms are temporary and will fade during the healing process. To help you through your recovery, let’s discuss why LASIK halos occur, what you can do about them, and on the rare occasion, when you should call a doctor.

What Are LASIK Halos, Glowing, and Starburst Visual Disturbances?

If you’ve ever looked at the headlight of an oncoming vehicle at night, only to see a bright circle around it, you’ve witnessed a halo. A glowing light or glare, on the other hand, looks like an odd level of brightness that appears near an object or as if it’s “coming off/from” and object, and appears somewhere in your field of vision. A starburst looks more like a glow that disperses around the light, rather than being a full circle around the light (halo). It’s very common to see all or a combination of these when you gaze at light sources straight-on, are near bright objects that are reflective, or look at shiny objects in low light conditions.

Is It Normal to Have Halos After LASIK Surgery?

Yes, it is completely normal to experience halos, glares, and starbursts after undergoing LASIK eye surgery. These visual disturbances are not something you should be overly worried about, as most patients do not find that they have a major impact on their daily lives.

Why Do LASIK Patients See Halos & When Do They Disappear?

During the LASIK procedure, an epithelium flap is created in the outermost layer of the cornea. This flap is lifted, giving us access to the cornea underneath, which is then adjusted to give you clearer vision without the need for glasses or contact lenses. Once the cornea has been reshaped using a laser, the flap is then replaced and allowed to heal naturally. As your eyes adjust to the new cornea shape and begins healing, “good” fluid accumulates in the cornea, leading to a bit of swelling. This swelling is what gives you the common side effect of LASIK halos. You can also experience halos if the cornea heals unevenly.

In some cases, halos and glow may occur due to the patient’s pupil size. If the pupil is larger than the area of correction, it can cause light to scatter, resulting in the appearance of halos, glare, glow, and starbursts. Additionally, if the patient experiences dry eyes, this increases the likeness of visual disturbances, which is why it’s recommended to follow the post-operative care as closely as possible. Finally, under or over-correction can cause halos, blurry vision, and glares when looking at bright lights.

How Long Will I See Halos For During the Healing Process?

You can expect to experience halos, glowing lights, and other visual disturbances at night like starbursts for at least the first 2–3 weeks of the healing process. It’s common for some patients to experience them for longer, though, with 1–3 months being a commonly reported time frame. For most individuals, the cornea swelling should subside within 3-months, and with it the halos should fade as well. If this time frame passes, and you’re still experiencing LASIK halos, glare, glowing, and starbursts, and they have NOT faded in their intensity or have worsened, then it’s time to contact your LASIK surgeon to have your eyes examined.

3 Remedies To Lower LASIK Halo Frequency

In terms of remedies, the best possible measure you can take is to follow the after-care instructions of your surgeon, as this will allow for the quickest recovery and subsequent relief from halos and glare. These instructions may include:


1. Prescription Eye Drops. Your doctor will prescribe you to use eye drops regularly, as they are designed to reduce inflammation, swelling, and dryness in the eyes. Not only will this reduce LASIK halos and glare, but will also speed up the healing process.

2. Special Lenses & Contacts. By limiting the amount of light that enters the eye, halos, and glare can be reduced without compromising your vision. However, you may notice that the effectiveness of these lenses are reduced at night. This is largely due to lights at night being more directional and focused than their ambient, day-time counterparts.

3. Further Surgery. Under and overcorrection can cause halos and glare, so it’s not uncommon for a surgeon to recommend LASIK enhancement surgery in cases where vision is continuing to be negatively impacted. This basically involves repeating the LASIK treatment, touching up problem areas with an excimer laser, and repositioning the corneal flap.

When Should I Call a Doctor For LASIK Halos?

While LASIK halos and other visual disturbances are expected during your recovery process, there are rare cases where it may be necessary to seek medical attention. If you experience sudden or severe visual disturbances, such as flashing lights or loss of vision, you should contact our team immediately, as something more serious may be going on that needs to be looked at. We also recommend that if the halos, glow, and starbursts do not steadily improve, or worsen and begin interfering with your daily activities, then that warrants a revisit with your surgeon.
