Tecnis Symfony® IOLs

What are Tecnis Symfony® Intraocular Lenses?

The first in a new category of intraocular lenses (IOLs), the FDA approved Tecnis Symfony lenses are the only lenses in the United States that provide a full range of continuous high-quality vision following cataract surgery, while also mitigating the effects of presbyopia (age-related farsightedness) by helping people focus on near objects. The FDA approval includes a version of the lens for people with astigmatism, the Tecnis Symfony Toric IOL.

Cataracts are a common condition, with almost 4 million cataract surgeries performed each year, and that number is expected to increase. By age 80, more than half of all Americans either have a cataract or have had cataract surgery. However, cataracts do not just impact seniors. In 2016 it is estimated that nearly one in four cataract surgeries will be performed on people younger than 65. Many people who have cataracts experience other problems with their vision, such as presbyopia and astigmatism, which the Symfony lenses also address. Presbyopia, which affects most people over age 40, means people have lost the ability to focus on objects up close and often require glasses to perform near visual tasks. Astigmatism is when the cornea is misshapen, which causes blurry or distorted vision.

The Symfony lens is approved in more than 50 countries around the world, and has been widely studied, with data from numerous clinical studies involving over 2,000 eyes. In clinical studies, the Symfony lens:

Provided seamless, day-to-night vision.

Patients could see objects sharply and clearly at near, intermediate and far away distances, and points in between.

Provided high-quality vision.

Some IOLs may leave patients with an inability to focus clearly due to competing wavelengths of light passing through the lens at different angles (known as chromatic aberration), or with vision that is not completely focused because of the shape of the lens (known as spherical aberration). The Symfony lens has been engineered to correct these issues.

Demonstrated a low incidence of halo and glare, which may be perceived as rings or blurring around bright lights.

Glare and halo can sometimes affect an individual's ability to drive at night or to perform other visual tasks.
