Halos & Glare After LASIK — You Don't Have to Live With This
Nighttime driving has become frightening. Streetlights explode into starbursts. You've been told to be patient — but years have passed. This is manageable. And you don't need more surgery to fix it.
You've been told this is just part of LASIK recovery and it will get better. For many patients it doesn't. And you've been told it's permanent. It often isn't. The truth is more nuanced — and more hopeful.
Why This Happens to Your Eyes
LASIK reshapes a central optical zone on your cornea — typically 6 to 6.5 millimeters in diameter. In bright daylight, your pupil is small (2–3mm) and sits entirely inside the treated area. Everything looks crisp. But in dim light, your pupil dilates to 7 or even 8 millimeters in some patients — extending well beyond the edge of the treated zone.
That transition zone between treated and untreated cornea scatters light. Your brain perceives this scatter as a halo or starburst around any bright light source. Streetlights, oncoming headlights, and lit signs all become visually disruptive. It's not your imagination, and it's not psychosomatic.
Beyond the optical zone mismatch, LASIK can introduce higher-order aberrations — subtle imperfections in the corneal surface that standard glasses prescriptions cannot correct. The most common are coma (a comet-like smearing of light) and spherical aberration (a soft glow around point sources). These are measurable with wavefront aberrometry, and they are treatable.
Some patients' halos improve significantly in the first year as corneal healing reduces surface irregularity. For others — particularly those with large pupils, high pre-LASIK prescriptions, or wavefront-guided ablations that didn't fully neutralize aberrations — the problem persists. That is where we help.
Solutions That Actually Work
For most post-LASIK halo patients, the answer is optical — not surgical. Here's what we offer.
Scleral Contact Lenses
Scleral lenses vault completely over the cornea, creating a smooth, tear-filled dome that optically neutralizes higher-order aberrations. Because the outer lens surface is perfectly regular, light passing through it is no longer scattered by the irregular LASIK-treated cornea underneath.
Most patients who try sclerals report dramatic improvement in night vision at their very first fitting appointment. Unlike glasses, which must work with the irregular corneal surface and therefore cannot fully correct aberrations, scleral lenses bypass it entirely.
Scleral Ortho-K
For post-LASIK patients who still have residual refractive error contributing to halos — particularly those who are now mildly myopic or hyperopic — scleral ortho-K lenses worn overnight can gently address that residual correction. Daytime vision without any lens wear improves, and halos tied to the refractive component often diminish.
Candidate selection matters. Dr. Bonakdar will assess whether your halo pattern is primarily refractive or primarily aberrational before recommending this approach.
Enhanced Pupil Management
Low-dose dilute pilocarpine drops can constrict the pupil in darkness, keeping it within the treated optical zone and reducing halos for patients who drive at night. This approach is conservative and appropriate for select patients.
We use this as an adjunct — not a primary solution — because it does not address the aberrations themselves and requires nightly application before driving.
Doctor's Insight: Halos After LASIK
Direct Answers from Dr. Bonakdar
Why do I see halos after LASIK at night?
Halos after LASIK result from the size difference between your corrected optical zone and your dark-adapted pupil size. When your pupil dilates in low light, it extends beyond the treated zone — the transition creates a halo or starburst around lights. Higher-order aberrations introduced by the ablation pattern also contribute.
Are halos after LASIK permanent?
Not always. Many patients see improvement over 6–12 months as the cornea heals. For those with persistent halos beyond one year, scleral contact lenses can dramatically reduce the effect by neutralizing the higher-order aberrations responsible.
Is LASIK enhancement safe if I have halos?
Enhancement surgery removes additional tissue from an already-altered cornea, which can increase ectasia risk. For many patients with optical zone-related halos, scleral lenses are a safer, more effective first line of treatment.
How quickly can scleral lenses reduce halos?
Most patients notice significant improvement at their first scleral lens trial appointment. Because sclerals vault over the cornea and create a smooth optical surface, they optically neutralize many of the aberrations causing halos and glare.

Specialty Post-LASIK Care Specialist
With over 35 years of clinical experience in specialty contact lens fitting and post-surgical vision care, Dr. Bonakdar has helped hundreds of patients recover the clear, comfortable night vision they expected from LASIK. He uses advanced optical quality analysis — including wavefront aberrometry — to identify exactly which aberrations are causing your symptoms, then designs a lens solution tailored to your corneal map. No two post-LASIK corneas are the same. Your solution shouldn't be generic.
What Our Patients Say
“I had LASIK six years ago and the halos at night were ruining my ability to drive. Three other eye doctors told me there was nothing they could do. Dr. Bonakdar fitted me with scleral lenses and at the first trial I could see streetlights as points of light again — not explosions. I cried in the exam room. I didn't know this was possible.”
