ICL surgery can improve optics but may introduce or highlight some glare or halos, particularly in large pupils, so sensitivity needs careful discussion.
Potential benefits
Reducing high‑power spectacles can sometimes help.
- Sharper focus may lessen some spectacle‑related starbursts
- No lens surfaces in front of the eye to reflect stray light
- Less dependence on contact lenses that dry and scatter light
- Possibility of improved contrast compared with thick glasses
- Adjustment and neuroadaptation can reduce perceived glare over time
Risks and considerations
Some patients remain light‑sensitive.
- ICL edges or vault may cause halos in very large pupils
- Any residual refractive error can contribute to starbursts
- Night‑time glare may persist, especially in high‑risk eyes
- Those extremely intolerant of optical phenomena may be less suitable
- Pre‑operative counselling and management of dry eye and other causes are vital
