Toric lenses are suitable for people with significant regular astigmatism who want clearer vision and less dependence on glasses after lens or cataract surgery.
When toric lenses help
Astigmatism occurs when the eye focuses differently in different directions. Toric lenses have built-in cylindrical power to correct this uneven focus.
- Moderate to high corneal astigmatism measured on scans and keratometry
- Desire to reduce or remove the astigmatic part of the glasses prescription
- Healthy cornea with regular, not highly distorted, astigmatism
- Suitable for monofocal, EDOF, and multifocal designs, depending on needs
- Willingness to accept that tiny residual astigmatism may remain
Key considerations
Toric lenses must align carefully with the steep axis of the cornea. Accurate measurements and surgical technique are essential for best results.
- Pre-operative scans confirm stability and regularity of astigmatism
- Lens design is chosen to match both sphere and cylinder power
- Rotation of the lens after surgery is rare but may need adjustment
- Small prescription tweaks with glasses are still possible if needed
- Detailed counselling explains expected distance and near dependence
