Stabilisation
Torelis Ext

- Back spherical optic zone with aspheric flattening
- Front multifocal-toric optic zone
- Dynamic stabilisation with bumps nasal and temporal
- Low corneal astigmatism, internal or combined astigmatism
- Marking at 0° and 180°
Torelis Int

- Back toric optic zone with aspheric flattening
- Front multifocal optic zone
- Dynamic stabilisation with bumps nasal and temporal
- Corneal astigmatism > 2.5 dpt improves stabilisation
- Curve difference over 0.50 mm
- Refraction axis = axis (rcfl) +/−10°
- Marking at 0° and 180°
Torelis Bal

- Back toric optic zone with aspheric flattening
- Front multifocal optic zone
- Ballast stabilisation
- Deep lower or upper eyelid
- Unsuccessful fitting with dynamic stabilisation
- Very large eyelid (> 11)
- Marking at 0° and 180°
