PRESBYOND‑type presbyopic enhancements can sometimes be performed after LASIK, but require especially cautious evaluation.
When post-LASIK PRESBYOND may be considered
Corneal and refractive stability are crucial.
- Stable refraction many years after LASIK
- Adequate residual stromal thickness and regular topography
- No signs of ectasia, flap issues, or significant dry eye
- Clear lenses with presbyopia now the main complaint
- Patient preferring corneal enhancement over lens replacement for the moment
Additional challenges
Re‑treating a LASIK cornea carries risks.
- Less tissue reserve for further ablation
- Higher risk of night‑vision symptoms and dry eye
- Biomechanics already altered by the original flap and ablation
- Need for highly experienced surgeons and detailed planning
- In some cases, refractive lens exchange is a safer presbyopia solution
