# Is ICL surgery suitable for astigmatism?

Yes. Toric ICLs are specifically designed to treat myopic or hyperopic astigmatism alongside the main spherical prescription.

## When toric ICLs work well

They correct both components in a single implant.

- Regular astigmatism typically up to about 3-6 dioptres
- Combined with moderate to high myopia or hyperopia within ICL limits
- Stable corneal shape without significant keratoconus or ectasia
- Precise rotational alignment at surgery to maximise effect
- Potential for excellent uncorrected vision when properly centred and oriented

## Considerations with astigmatic ICLs

Alignment and stability are critical.

- Preoperative marking and imaging to determine correct axis
- Follow‑up to ensure the lens has not rotated significantly
- Possibility of minor residual astigmatism managed with glasses or small laser tweaks
- Alternative strategies if astigmatism is irregular or linked to corneal disease
- Recognition that accurate biometry is essential for a predictable outcome
