# Is PRESBYOND surgery suitable for high myopia?

PRESBYOND is more limited in high myopia, because larger corrections remove more tissue and may exceed safe corneal thresholds.

## Concerns with high myopia

Biomechanical safety is critical.

- Deep ablations can weaken the cornea and increase ectasia risk
- Higher myopes often have thinner or more marginal corneal profiles
- Residual stromal bed must remain well above safety minima
- Risk of regression or visual quality issues rises with very high corrections
- High myopia also carries retinal risks independent of the cornea

## Alternative strategies

Lens‑based options often perform better.

- ICL or other phakic IOLs for high myopes with clear lenses
- Lens replacement if there are early cataract or presbyopic needs
- Combination approaches tailored by a refractive specialist
- Continued glasses or contact lenses when surgical risk outweighs benefit
- Thorough evaluation is essential before considering PRESBYOND in high myopia
