An extended depth of focus lens is an integral part of the Lifestyle Premium lens implant menu at The Harman Eye Clinic in Arlington WA.
In 2016 the Food and Drug Administration approved two new types of intraocular lenses for use in cataract surgery—the and TECNIS SYMFONY® toric lens implants.
“The Symfony® intraocular lens is the option of choice that I can offer my patients to improve their vision following cataract surgery, especially those who have difficulty focusing on objects at near distances because of presbyopia,” said Dr. Bajenova.
The Symfony® lens improves intermediate (and in many cases near vision), thereby treating presbyopia. The Symfony® toric lens not only corrects presbyopia, but also astigmatism.
“Many of my patients live very active lifestyles and want to see clearly at all distances, and without glasses if possible,” said Dr. Ballon. “With the Symfony® lens, I can give patients the freedom to enjoy the activities that matter to them, while wearing glasses less.”
Traditional Cataract Surgery compared to an Extended Depth of Focus lens
During cataract surgery, the natural lens of the eye is removed, and an artificial lens, called an intraocular lens, or IOL, is inserted into the eye. Many patients still believe the only IOL available to them is a traditional monofocal lens, which only allows the person to see at a distance, with closer objects being out of focus.
“We take extra time during a patient visit to explore IOL options,” said Dr. Wietharn. It takes more time with staff and myself to introduce new concepts but we think every patient should be aware before surgery, whether or not they wish to take advantage of state-of-the-art technology.”
In contrast to the traditional, standard IOL, the Symfony® lens was specifically developed with features to improve both the range and quality of vision.
The Importance of Pre-Surgical Discussions with your Surgeon
“There is nothing as good as the original equipment from the manufacturer when you are a teenager,” says Dr. Ballon. “That said, the Symfony® lens is the best addition to our lens inventory to date.”
Symfony® lens is successful because it provides a continuous range of focus for both distance and intermediate (computer) vision. Patients who continually require absolute fine detailed vision, such as accountants or those who like to read paper, small-print books in bed without glasses may appreciate a comparison discussion over Technis multifocal lens and Symfony®. These patients who have the Symfony® lens may choose over the counter reading glasses (+1.50 cheaters) for fine print. Others who require fine-print access leave behind need for reading glasses by using their computers, smart phones and pads, to do their reading in bed and fine print projects. It is important to discuss comparison options before surgery by sharing your lifestyle and vision expectations.
The Symfony® lens also offers excellent quality of vision without loss of contrast sensitivity. Some patients who may not be a candidate for the Tecnis Multifocal lens due to, say, an epiretinal membrane (wrinkle in the macula) which may decrease contrast sensitivity, for example, may still be a candidate for the Symfony® lens. Presently, it is the only lens on the market that corrects chromatic aberrations, a feature that improves reading ability. The rings are larger than the Tecnis Multifocal lens, so that halos at night are much less prominent. Patients under the age of 60 tend to tolerate the Symfony® lens much better than multifocal lenses. Although the Symfony® lens is designed for bilateral implantation, patients with a cataract in just one eye seem to tolerate the Symfony® lens well, but the full benefits of reading are best when it is implanted bilaterally.
A LifeStyle Worksheet is available for our patients so that they can prepare. Many patients come for cataract surgery consultations with little or no information about what we call LifeStyle lens implants. The Symfony® is one such lens. Much of the senior population have come to accept that glasses are a part of their life. Some will even say that they like wearing glasses. That is fine, if true. Patients who were eligible and chose to have a LifeStyle lens implant continue to tell us how grateful they are to get up in the morning, look out the window, read the time on their smart phone, and remember how good it is to see with little or no dependence on glasses.
TAKE AWAY POINTS:
- Extended depth of vision was approved by the FDA in 2016
- Symfony® and Symfony® toric lenses can extend depth of vision: far, intermediate, and near
- Symfony® and Symfony® toric lenses can offer quality of vision without loss of contrast sensitivity.
- The traditional lens implant for cataract surgery is a monofocal lens (vision for one point of vision). Reading glasses and glasses for intermediate vision is expected after surgery.
- To proceed with confidence, prepare by listing your lifestyle vision requirements and expectations before meeting your cataract surgeon.
