What Is Astigmatism?
Astigmatism is a common eye condition where the cornea or natural lens has an irregular shape, causing distorted or blurred vision.
Common Symptoms of Astigmatism
- Blurred vision
- Distorted images
- Eye strain
- Halos around lights
- Poor night vision
- Frequent spectacle power changes
Astigmatism may occur along with:
At ASG Eye Hospital, advanced corneal scans and measurements help determine the exact amount and axis of astigmatism before surgery.
How Toric IOLs Work
Toric intraocular lenses are designed with different optical powers in specific meridians to correct astigmatism.
During cataract surgery:
- The cloudy natural lens is removed
- The toric lens is implanted
- The lens is precisely aligned according to the astigmatism axis
Correct alignment is essential for achieving clear and stable vision.
Benefits of Toric Intraocular Lenses
Cataract & Astigmatism Correction Together
Toric lenses help treat:
in a single procedure.

Toric IOLs can significantly reduce the need for distance spectacles after cataract surgery.
Better Night Vision Quality
Correcting astigmatism may improve:
- Contrast sensitivity
- Night driving comfort
- Low-light visual clarity
Stable & Predictable Outcomes
Modern toric lenses are designed for:
- Rotational stability
- Precise alignment
- Reliable long-term performance

Provide:
- Astigmatism correction
- Near vision
- Intermediate vision
- Distance vision
These premium lenses help reduce spectacle dependence.
Trifocal Toric IOLs
Advanced trifocal toric lenses improve:
- Reading vision
- Computer vision
- Distance vision
- Astigmatism correction
Especially useful for:
- Digital screen users
- Professionals
- Active lifestyle patients
