New Technology Can Offer People with Cataracts
Health Canada approves TECNIS® Symfony Extended Range of Vision intraocular lens
TORONTO, Sept. 16 2015 — Abbott announced today it received Health Canada’s approval of the TECNIS® Symfony Extended Range of Vision intraocular lens (IOL) for the treatment of people with cataracts who may also have a diminished ability to focus on near objects (presbyopia). It is the first and only extended range of vision IOL to correct presbyopia and help people with cataracts see better at all distances, including far, intermediate and near, and points in between, with decreased need for glasses.
A cataract is a gradual clouding of the natural lens of the eye that prevents light from reaching the retina. More than 2.5 million Canadians have cataracts. The incidence of cataracts increases with age from about 12 per cent at age 50, to 60 per cent at age 70. In general, approximately 50 per cent of Canadians 65 years of age or older have cataracts.
“The availability of the TECNIS Symfony IOL is welcome news for many of my patients,” said Sheldon Herzig, M.D, co-founder and medical director, Herzig Eye Institute, Toronto. “The new lens effectively improves both near and distance vision without glasses following cataract surgery, while maintaining excellent night vision. Eliminating the need for reading glasses has been one of my patients’ greatest needs and has a significant impact on their quality of life.”
Traditionally after cataract surgery, people may still require eyeglasses. However, a clinical study of 31 people who had the TECNIS Symfony IOL implanted showed 70 per cent of them reporting rarely or never requiring wearing glasses. One hundred per cent of people who had the lens implanted reported they did not need to wear glasses for seeing objects at distance, while 94 per cent and 87 per cent of people reported the same results at intermediate and near distances, respectively.
The TECNIS Symfony lens differs from traditional technologies with its unique design that elongates the eye’s focus across a continuous range of distances, without sacrificing a person’s visual clarity or contrast. The IOL is designed to be placed in the lens capsule of the eye, replacing the natural crystalline lens that has been removed because of a cataract…….
