Toric Lenses
Toric lenses are intraocular lenses developed for people with astigmatism.
They may be used during cataract surgery or lens replacement surgery.
The aim is to help correct corneal astigmatism while treating the cataract.
What Is Astigmatism?
Astigmatism is a refractive error that occurs when the front surface of the eye differs from an ideally round shape.
It may cause blurred vision at both distance and near.
Astigmatism is also an important factor to assess in people planning cataract surgery.
Features of Toric Lenses
- Have a specialised optical design intended to correct astigmatism.
- May be used during cataract surgery.
- Aim to reduce the effect of astigmatism on vision.
- Options are available for different degrees of astigmatism.
The Importance of Astigmatism in Lens Selection
In cataract surgery, both the degree of cataract and the degree of astigmatism are assessed.
In some people, correcting astigmatism may have a noticeable effect on postoperative vision.
Preoperative measurements and planning are therefore very important.
Who May Consider Toric Lenses?
Toric lenses are one option that may be considered for people with corneal astigmatism.
Suitability is determined following a comprehensive eye examination and biometric measurements.
Lens Selection
Today, monofocal, toric, EDOF and multifocal lenses are designed for different needs.
Toric lenses are considered particularly when correction of astigmatism is a treatment goal.
The choice of lens is determined according to the eye anatomy and measurements.
