New Intraocular Lens helps people with cataracts see better at all distances, minimises need for spectacles


The term ‘cataract surgery’ often conjures images of elders and grandparents wearing spectacles, straining to read small text and having trouble with bright lights at night. Cataract surgery is one of the most common surgeries in India, with over 6.2 million procedures in 2013-141.  The condition is also the leading cause of blindness, according to the National Programme for Control of Blindness (NPCB) 2.

Cataracts require replacing the clouded natural lens in the eye with an intraocular lens (IOL). Intraocular lenses (IOLs) today may correct presbyopia (poor ability to focus on near objects), or offer quality vision only at distinct distances, such as near and far, while vision between these distances may be reduced. With almost a third of the world’s cataract procedures estimated to be occurring in India3, and with elders having more active lifestyles, the demand for newer technologies that offer better functional vision and independence from spectacles is increasing.

Abbott today announced the launch of its revolutionary technology, the TECNIS Symfony® Extended Range of Vision IOL in India, enabling doctors to offer people with cataracts a continuous range of high-quality functional vision for far, intermediate, and near distances, with a reduced incidence of halo and glare, comparable to a standard monofocal lens4.  Halos are bright circles that appear to surround a source of light, such as an oncoming car’s headlights. Glare is light that enters the eye but doesn’t help one see better. Rather, it interferes with vision. Glares can be uncomfortable as the extra brightness may result in squinting and tears in the eye.

The TECNIS Symfony® IOL is a first-of-its-kind presbyopia-correcting lens designed to reduce the need for spectacles and provide a significant advancement over traditional IOL technologies. The   lens is designed to increase the distance over which an object appears in focus across a continuous range of distances, without sacrificing a person’s visual clarity or contrast.

“As people age, the inability to focus and see clearly is a major challenge. Constantly handling glasses can be cumbersome. The Symfony IOL now offers vision correction for life. Post cataract surgery, patients have reported getting back vision which mimics the vision they had in their youth.” said Dr. Ramamurthy, Chairman, The Eye Foundation, Coimbatore.
