When Do Halos Go Away After LASIK?

Many people choose LASIK because they want to see clearly without glasses. The surgery is fast, safe, and has helped millions of people. But right after LASIK, some patients notice “halos.” Halos look like glowing rings around lights, especially at night. This can feel scary, but in most cases, halos are normal and temporary.

At VESELY Augenklinik in Bratislava, we help patients understand what to expect before and after LASIK. In this blog, we explain why halos happen, how long they last, and when you should talk to your doctor. Our goal is to give you simple, clear facts so you feel calm and informed.

What are halos?

Halos are circles of light you may see around lamps, headlights, or streetlights. They can look like a glow or mist around a bright object. Many people see halos in dark places or when driving at night.

Why do halos happen after LASIK?

LASIK reshapes the cornea so you can see without glasses. After the treatment:

• The surface of the eye needs time to heal
• Your tears change for a short period
• Your brain adjusts to the new vision
• Light may bend differently than before

Because of these changes, halos are common. Almost everyone gets them to some degree after laser eye surgery.

How long do halos last?

Typical timeline:

• First 24–48 hours: Halos are strongest. Vision may feel misty.
• First week: Many patients notice improvement.
• 1–3 months: Halos continue to fade as the cornea stabilises.
• 3–6 months: In most cases, halos are almost gone.
• After 6 months: Most people no longer notice halos at all.

Each person heals differently. Some people recover fast, while others need a little more time.

What helps halos fade faster?

There are simple steps you can take to help your eyes heal well:

1. Use your eye drops

Your doctor will give you drops to keep your eyes moist and clean. Using them as instructed helps reduce halos.

2. Rest your eyes

Your eyes work hard every day. Blink often and give them breaks, especially after using screens.

3. Avoid bright lights at first

Wear sunglasses outside. Try not to drive at night for the first few days.

4. Follow your check-ups

Regular visits help your doctor track your healing and adjust treatment if needed.

Are halos ever permanent?

In most cases, halos go away. Only a very small number of people have halos that stay for longer. This can happen if:

• The cornea heals slowly
• The pupil is very large
• The correction needed was very strong
• The eyes are naturally dry

If halos last longer than 3–6 months, your doctor may give extra drops, lenses, or another small treatment to help.

When should you call your doctor?

Most halos are normal. But you should contact your clinic if:

• Halos get worse instead of better
• You feel sharp pain
• Vision suddenly becomes very blurry
• You see dark shadows
• Light hurts your eyes a lot

At VESELY Eye Clinic, we want you to feel safe every step of the way. Never hesitate to ask questions.
