Laser eye surgery can sometimes reduce night glare, especially if caused by uncorrected prescription or corneal irregularity, but it can also introduce or worsen halos in some people.
When surgery may help
In carefully chosen eyes, improving focus and corneal regularity can make lights appear clearer.
- Night glare mainly due to high prescription or astigmatism
- Normal topography and sufficient corneal thickness
- Use of wavefront‑guided or topography‑guided treatments to reduce aberrations
- Good tear film and controlled dry eye
- Realistic understanding that mild halos are still common early on
When existing glare is a warning sign
Sometimes marked glare points to issues that make laser less suitable.
- Underlying corneal disease, early cataract, or retinal problems
- Very large pupils relative to the planned optical zone
- Extreme sensitivity to visual imperfections that might worsen satisfaction
- Alternative strategies such as lens surgery or updated glasses providing more predictable improvement
- Decision after detailed discussion of risks versus likely benefit
