Night vision quality is one of the most common concerns before LASIK — and with modern AI laser technology, outcomes are significantly better than with older-generation systems.
LASIK and Night Vision — What to Expect
In the first 2–4 weeks after LASIK, many patients notice halos, glare, or starbursts around lights at night. This is completely normal and caused by pupil dilation in low light exposing the edge of the treatment zone. As the cornea heals, these symptoms resolve in the vast majority of cases.
Timeline for Night Vision Improvement
- Weeks 1–2: Halos most noticeable
- Weeks 3–6: Significant improvement as healing progresses
- Months 2–3: Most patients report halos are minimal or gone
- Month 6: Final night vision quality established
How Modern AI Laser Technology Reduces Halos
Our 7th Generation AI laser platform uses a large optical zone treatment (6.5–7.5mm diameter) — significantly larger than older LASIK systems. This means even in dim light with a dilated pupil, the entire pupil is within the treatment zone, dramatically reducing halo formation. Contoura Vision and InnovEyes also correct higher-order aberrations that contribute to glare and halos.
Can LASIK Actually Improve Night Vision?
Yes — for patients with significant higher-order aberrations, Contoura Vision and InnovEyes can produce better night vision than glasses or contacts.
