PRESBYOND provides long‑lasting corneal reshaping that is effectively permanent, though natural ageing changes will still occur.
What “permanent” means
The cornea is reshaped for the long term.
- Laser permanently alters corneal curvature to create blended‑vision optics
- Effects are designed to last for many years without daily maintenance
- Lens ageing and cataract may later change vision irrespective of laser
- Further procedures may be needed if cataract develops or refraction shifts
- Surgery should be approached as a lasting change, not a reversible trial
Who this suits best
Some prioritise durability over reversibility.
- Presbyopes comfortable with permanent corneal modification
- Stable prescription and healthy ocular structures
- Understanding that occasional glasses may still be useful
- Acceptance that future lens surgery might alter the blended‑vision balance
- Preference for a one‑off surgical solution rather than ongoing spectacle use
