# When is PRESBYOND surgery not recommended?

PRESBYOND is not recommended when corneal, lens, or retinal health, systemic factors, or expectations make the risk-benefit balance unfavourable.

## Ocular reasons to avoid PRESBYOND

These conditions typically exclude blended‑vision laser.

- Thin, irregular, or ectatic corneas (for example keratoconus)
- Unstable prescription or suspicious topography
- Early or established cataracts or significant macular disease
- Advanced glaucoma or poorly controlled ocular hypertension
- Severe dry eye or autoimmune‑related ocular surface disease

## Other situations where it is inadvisable

Health and preferences also matter.

- Pregnancy, breastfeeding, or poorly controlled systemic illness
- Highly risk‑averse patients or those demanding "perfect" vision
- People content with spectacles or contact lenses experiencing little inconvenience
- Inability to attend follow‑up visits or follow aftercare instructions
- Better candidacy for lens replacement, ICL, or non‑surgical options
