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
