Cataracts & Astigmatism

Can I have my astigmatism fixed along with my cataracts?
A common question we hear from patients. Dependent on the degree of astigmatism and what type of astigmatism (lenticular or corneal), you may have the option of correcting both with one lens implant.
Toric Lens Implants are a type of Lens Implant that can correct astigmatism. Astigmatism is an optical aberration that is caused by the cornea being shaped more like a football, than spherical like a baseball. For Cataract patients who have astigmatism, and who do not wish to wear eyeglasses to see clearly at a distance, choosing a Toric Lens Implant can help them be independent of glasses for tasks such as driving, that require clear distance vision. In addition, for those who desire the clarity provided by an Aspheric Lens Implant (IOL), there is an Aspheric Toric IOL that offers an enhanced aspheric optical zone that improves image quality and increases contrast sensitivity for Cataract patients with astigmatism.
Toric Lens Implants do not correct Presbyopia, and thus even with Toric Lens Implants to correct astigmatism after Cataract Surgery, most patients still require reading glasses to be able to comfortably perform near vision tasks such as reading.
