# Is cataract surgery suitable after LASIK?

Cataract surgery is usually suitable after LASIK, but calculating the new lens power needs extra care because the cornea has already been reshaped.

## Key considerations after LASIK

Special measurements and formulas are used.

- Detailed corneal scans and historic data, if available, to refine calculations
- Realistic expectations that tiny prescription surprises are more common
- Preference for monofocal or toric lenses unless carefully counselled otherwise
- Discussion of how prior LASIK (e.g. monovision) influences target focus
- Close follow‑up with the option of glasses or minor laser fine‑tuning if needed

## When surgery may be less straightforward

Irregular or high‑risk corneas need individual planning.

- Evidence of ectasia, scarring, or very thin residual cornea
- Significant dry eye affecting measurements and visual quality
- Large optical zones that make multifocal lenses less predictable
- Need for extra counselling about night‑vision symptoms and contrast
- Collaboration with a refractive specialist familiar with post‑LASIK eyes
