PresbyMAX can treat regular astigmatism together with presbyopia, offering multifocal corneal correction tailored to both distance and near.
When astigmatic presbyopes are good candidates
Regularity and magnitude matter.
- Regular corneal astigmatism typically up to about 3 dioptres
- Stable refraction with healthy, symmetrical topography
- Presbyopia causing bothersome reliance on multifocal glasses
- Clear natural lens and good retinal health
- Readiness to adapt to multifocal corneal optics and potential night‑time phenomena
Limitations and alternatives
Not all astigmatism is suitable for laser.
- Irregular astigmatism or keratoconus, where laser may worsen vision
- Very high astigmatism exceeding platform capability
- Cases better suited to toric ICLs or toric lens implants
- Need for detailed mapping and sometimes cross‑linking before considering corneal surgery
- Choice made after comparing corneal, phakic, and lens‑replacement options
