VIVITY vs CLEARVIEW 3 - Which Lens is Better?

www.EyeOC.com   / doctorkrad   Within a healthy eye is a clear lens. As we become older, that lens becomes cloudy. The cloudy lens is called a Cataract. In cataract surgery, the cloudy lens is removed and replaced with a clear artificial lens implant (IOL). There are many types of IOL's, including those that treat presbyopia in order to reduce dependence on reading glasses. Multifocals historically provided the strongest reading vision, but they are associated with dysphotopsias such as halos, glare, and starbursts at night. In order to reduce dysphotopsias, extended depth of focus lenses came out such as the Vivity and Symfony IOL's. They provide some mid-range/intermediate reading vision with less severe dysphotopsias at night. The Vivity lens has a more favorable night time profile than the Symfony, so it has gained popularity. Now, the Clearview multifocal IOL is available and has an impressive night time dysphotopsia profile, and stronger reading vision that the Vivity and Symfony. In this case, a patient has the Vivity in one eye, and the Clearview in the other. He shares his experience and lets us know which lens he likes better.
