Lens replacement surgery can be suitable for people with astigmatism, particularly when combined with a toric lens implant designed to correct the uneven focus.
How astigmatism is treated
Astigmatism occurs when the front of the eye or lens is more curved in one direction. Specially shaped implants can offset this, giving clearer distance and sometimes near vision.
- Toric intraocular lenses are chosen to match the amount of astigmatism
- They can be combined with multifocal or extended range designs
- Accurate measurements and careful positioning are essential
- Can reduce or remove the need for cylindrical power in glasses
- Helpful when laser reshaping is not suitable or desired
Limits and expectations
Some people may still have a small amount of astigmatism after surgery. Understanding likely outcomes beforehand helps avoid disappointment and supports a smooth adjustment.
- Very high or irregular astigmatism may not be fully correctable
- Previous corneal surgery or scarring can affect results
- Fine-tuning with glasses or later laser enhancement might be offered
- Night-time visual effects can occur, especially with multifocal lenses
- Follow-up checks confirm that the toric lens remains correctly aligned
