TECNIS® Symfony IOL – New Lens Technology for 2016
In July 2016, the U.S. Food and Drug Administration (FDA) approved the TECNIS® Symfony Intraocular Lenses for the treatment of cataracts. The first in a new category of intraocular lenses (IOLs), the TECNIS® Symfony lenses are currently the only lenses in the United States that provide a full range of continuous high-quality vision following cataract surgery at distance while also mitigating the effects of presbyopia by helping people focus on intermediate to near objects. The FDA approval also includes a version of the lens for people with astigmatism, which is the TECNIS® Symfony Toric IOL.
Cataracts are a very common condition, with almost four million cataract surgeries performed each year. By age 80, more than half of all Americans either have a cataract or have had cataract surgery. Although cataracts primarily impact seniors, it is estimated that nearly one in four cataract surgeries will be performed on people younger than 65. Many people who have cataracts experience additional problems with their vision, such as presbyopia and astigmatism, which the Symfony lenses also address. Presbyopia, which affects most people over age 40, is the condition in which people have lost the active focusing ability to see objects up close and at a distance simultaneously. Most often, people require glasses or contacts to perform near visual tasks. Astigmatism occurs when the cornea is more oval-shaped than rounded, which causes blurry or distorted vision.
“The Symfony intraocular lens is an excellent new option I can offer my patients to improve their vision following cataract surgery, especially those who have difficulty focusing on objects at a close range and at a distance because of presbyopia and the overall blurriness related to astigmatism, [which can be addressed] with the Symfony Toric lens,” said Helga F. Pizio, M.D., our experienced cataract surgeon here at New Eyes. “Many of our Las Vegas patients live a very active lifestyle and want to see clearly at all distances without requiring glasses or contacts. With the Symfony lens, I can give most patients the freedom to enjoy the activities most important to them, while wearing glasses less or not at all.”
During cataract surgery, the natural lens of the eye is removed, and an artificial lens, called an intraocular lens (IOL) is inserted into the eye. The IOL most commonly used in cataract surgery is a monofocal lens, which allows the person to improve distance or near vision only and not both at the same time. Patients who choose distance only with a monofocal IOL will require reading glasses for intermediate and near objects. In contrast, the Symfony lens was specifically developed with features to improve the range for excellent distance, intermediate, and near vision without glasses and maintain the quality of vision throughout that range.
The FDA approval was based on results of a pivotal U.S. study that compared the TECNIS® Symfony lens to a TECNIS® aspheric monofocal lens in 298 patients. Compared with patients in the monofocal group, those who received a TECNIS® Symfony IOL achieved greater improvements in intermediate and near vision while maintaining similar distance vision. Patients in the Symfony group were also more likely to achieve reduced overall spectacle-wear and high overall visual performance in any lighting condition. Rates of adverse events did not differ between the Symfony and monofocal groups.
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, as well as 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 effects can sometimes impact an individual’s ability to drive at night or to perform other visual tasks.
