Premium Contact Lenses
The Symfony Extended Range of Focus intraocular lens implant
Dr. Luis Washington Lu at the Eye Consultants of Arizona is pleased to provide the Tecnis Symfony® Intraocular Lenses for the treatment of cataracts. The Symfony implant is a new category of intraocular lenses (IOLs), which are utilized to replace a patient’s natural lens removed during cataract surgery.
The Tecnis Symfony are the only lenses in the United States that provide Extended Range of continuous high-quality vision following cataract surgery. These lenses mitigate the effects of presbyopia by helping people focus on near objects. Presbyopia is the blurring of reading vision that comes with aging.
The FDA approval includes a version of the lens for people with astigmatism, the Tecnis Symfony Toric Implant. Astigmatism is a condition where the front surface of the eye is curved differently in areas. This results in blurriness to the patient’s vision. These patients with astigmatism may now have options to maintain or return their reading and distance vision with the Symfony Toric IOL.
Cataracts are a common condition. There are almost 4 million cataract surgeries performed each year, and as the American population ages this number is expected to grow. However, cataracts do not just impact seniors. In 2016 it is estimated that nearly 25% of 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.
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. The IOL most commonly used in cataract surgery is a monofocal lens, which only allows the person to see at a distance, with closer objects being out of focus. In contrast, the Symfony lens was specifically developed with features to improve both the range and quality of vision.
The Symfony Lens has 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.
If you or a family member would benefit from these Symfony lenses or other options available with cataract surgery, contact Dr. Lu at the Eye Consultants of Arizona, and schedule a consultation.
