# Is PRESBYOND surgery suitable if you have thin corneas?

Thin corneas often limit or exclude PRESBYOND, because safe laser ablation requires adequate tissue thickness.

## Why thin corneas are a concern

Excess tissue removal risks instability.

- Higher chance of post‑operative ectasia if residual stromal bed is too thin
- Restricted ability to correct both distance and presbyopic components safely
- Increased sensitivity to measurement errors and regression
- Need to respect strict minimum thickness guidelines
- Many thin‑cornea patients are better suited to non‑corneal options

## Alternatives for thin‑cornea presbyopes

Other strategies may be safer.

- ICL or other phakic IOLs with or without reading glasses or monovision
- Lens‑based presbyopia solutions such as multifocal or EDOF implants
- Optimised spectacle or contact‑lens strategies
- In some cases, no surgery if risk outweighs benefit
- Full corneal mapping is essential before deciding
