# Is PRESBYOND surgery suitable for astigmatism?

PRESBYOND can treat regular astigmatism alongside presbyopia, provided the cornea is otherwise healthy.

## When astigmatic presbyopes are good candidates

Regularity and magnitude are key.

- Regular corneal astigmatism typically up to about 3 dioptres
- Stable refraction with symmetrical, healthy topography
- Presbyopia causing bothersome dependence on multifocal spectacles
- Clear crystalline lens and good macular health
- Willingness to adapt to blended‑vision optics and possible night‑time phenomena

## When astigmatism limits suitability

Irregular or high astigmatism may need alternatives.

- Irregular astigmatism or keratoconus where laser may worsen vision
- Very high astigmatism beyond platform capability
- Eyes better served by toric ICLs or toric lens implants
- Potential need for cross‑linking or rigid lenses in ectatic corneas
- Comprehensive corneal mapping guides the safest option
