Quick Overview
Seeing glare or halos around lights — especially at night — is a common visual symptom after procedures like LASIK or cataract surgery.
This occurs due to temporary changes in the cornea or lens implant, which alter how light enters the eye.
Most patients notice improvement over weeks to months as the eyes heal and adapt to the new optical surface.
When to Take It Seriously (Risk Level: Low to Medium)
Mild halos and glare are expected during early recovery.
But if they persist beyond 3–6 months, worsen at night, or are accompanied by blurred vision, they may indicate issues like residual refractive error, dry eye, or lens misalignment.
Common Causes
- Corneal swelling or irregular healing after LASIK
- Residual refractive error or astigmatism
- Pupil dilation in low light
- Posterior capsule opacity (after cataract surgery)
- Tear film instability or dryness
- Type of intraocular lens (multifocal lenses cause more halo perception)
Associated Symptoms
- Rings or halos around headlights and streetlights
- Starburst or glare when looking at bright light sources
- Blurred or hazy vision in dim lighting
- Dryness or discomfort in the eyes
- Light sensitivity during recovery
- Difficulty driving at night
Possible Conditions
- Post-LASIK Glare or Halo
- Posterior Capsule Opacification (Secondary Cataract)
- Dry Eye-Related Vision Disturbance
- Pupil Dilation-Related Light Scatter
- Refractive Residual Error
Diagnostic Steps
Your eye specialist may perform:
- Corneal topography to assess surface regularity
- Wavefront analysis for optical aberrations
- Refraction test for residual power correction
- Slit-lamp exam to check for lens clouding or capsule opacity
- Tear film evaluation for dryness
- Pupil size assessment under different lighting conditions
Treatment Options
Treatment depends on the underlying cause and severity.
- Lubricating eye drops for dryness-related halos
- Anti-reflective lenses for glare reduction
- Prescription glasses or contact lenses for minor residual power
- Laser enhancement (touch-up) after LASIK if residual error persists
- YAG laser capsulotomy for capsule clouding post-cataract surgery
- Pupil-constricting drops (pilocarpine or brimonidine) in select cases
With appropriate management, most patients regain clear and comfortable night vision.
Home Care / Self-Care Tips
- Avoid driving at night until symptoms improve
- Use lubricating drops before bedtime and screen work
- Reduce screen brightness and increase ambient room lighting
- Use anti-glare glasses for night driving
- Avoid staring at bright light sources directly
- Rest eyes regularly to prevent dryness and fatigue
- Attend scheduled follow-up appointments for monitoring
When to See a Doctor
Consult your eye surgeon if you:
- Experience persistent or worsening glare or halos beyond 3 months
- Notice sudden haziness or foggy vision
- Have severe dryness or discomfort
- Struggle to drive safely at night
- Observe decreased contrast or cloudy vision after cataract surgery
These could indicate a correctable issue like lens misalignment or capsule clouding.
FAQs
Q1: Are halos after LASIK normal?
Yes, mild halos are common and usually resolve as the cornea heals within 3–6 months.
Q2: Do all cataract patients experience glare?
Not all. It’s more frequent in those with multifocal or premium lenses.
Q3: Can eye drops reduce glare?
Yes, lubricating or pupil-constricting drops can help reduce light scatter.
Q4: Will a second laser procedure fix halos?
In some cases, a LASIK enhancement can smooth irregularities causing glare.
Q5: Are halos permanent?
Rarely. They typically fade with healing or after addressing the cause.
