A toric IOL has different powers in different meridians to reduce suitable regular corneal astigmatism. Toric optics can be combined with monofocal and selected presbyopia-correcting lens designs.
Suitability depends on the amount and regularity of corneal astigmatism and the reliability of corneal measurements.
Astigmatism caused by an irregular or scarred cornea may not respond like regular corneal astigmatism. Keratometry and, when indicated, corneal topography or tomography help the surgeon understand the pattern.
A well-planned toric lens can reduce residual astigmatism and dependence on distance glasses, but it does not guarantee spectacle-free vision.
Toric describes cylinder correction rather than focus range. A toric lens may still be monofocal, EDOF or multifocal, so near-vision expectations must be discussed separately.
The lens is positioned on a calculated axis. Rotation or residual prescription can reduce the intended correction and may require further management.
The axis is planned before surgery and checked when the IOL is placed. If the result differs from the target, glasses, lens repositioning or another treatment may be considered after the eye is assessed.
This page provides general patient information. Your examination, surgeon’s advice and written treatment instructions determine what is appropriate for your eye.
