# Is ICL surgery suitable if you have large pupils?

ICL surgery can be performed in people with large pupils, but the risk of halos, glare, and night‑vision symptoms needs special attention.

## Potential issues with large pupils

More light passes through peripheral optics.

- Increased chance of seeing lens edges or optical aberrations in low light
- Greater sensitivity to halos around lights at night
- Higher risk of glare if lens centration or vault is suboptimal
- May influence the choice between different refractive options
- Requires thorough counselling about night‑vision expectations

## Mitigating strategies

Planning can reduce symptoms.

- Accurate centration and sizing of the ICL
- Careful assessment of scotopic pupil size during workup
- Exploring impact with simulation and discussion of potential trade‑offs
- Advice on driving and lighting while adapting after surgery
- Considering alternative procedures if very large pupils make visual quality uncertain
