# Is laser eye surgery suitable for astigmatism?

Laser eye surgery can treat many forms of regular astigmatism and is commonly used to reduce or remove astigmatic prescriptions.

## When astigmatism is suitable

Regular, symmetric astigmatism can usually be incorporated into the laser pattern, correcting both sphere and cylinder together.

- Consistent cylinder values on your glasses and repeated measurements
- Topography showing a regular bow-tie pattern rather than distorted maps
- Corneal thickness sufficient to treat combined myopia/hyperopia and astigmatism
- No signs of keratoconus or ectasia-prone corneas
- Expectations that small residual astigmatism may still require thin glasses occasionally

## When astigmatism needs caution

Irregular or unstable astigmatism may signal underlying corneal disease, where tissue-removing laser is unsafe.

- Asymmetric or highly irregular topography suggesting early ectasia
- History of corneal scarring, infection, or surgery
- Marked difference in astigmatism between eyes
- Consideration of cross-linking, specialist lenses, or other options instead
- Thorough evaluation by a refractive surgeon experienced in corneal diagnostics
