Does the Vivity IOL treat astigmatism?
The Vivity IOL can treat patients with myopia, hyperopia, presbyopia, and astigmatism. Astigmatism is when the clear surface of the eye called the cornea is slightly oval shaped rather than being perfectly round. If astigmatism is not corrected at the time of cataract surgery, vision may be blurry or distorted. The Vivity IOL is available in different power types to reduce astigmatism for patients that need it. The eye will be measured before cataract surgery with intraocular biometry and topography to measure the amount of astigmatism present.
