WHAT IS A CATARACT?
The natural lens of the eye is made mostly of water and protein. Sometimes, as the eye ages, some of the proteins undergo changes, causing the eye’s lens to become discolored and clouded. This is called a cataract.
When this occurs, light passing through the eye becomes scattered and unfocused. The result is that all objects near and far, become blurry. The only treatment for a cataract is removal of the natural lens and implantation of an intraocular lens (IOL). This restores the eye’s ability to have light pass unobstructed through to the retina.
WHAT IS PRESBYOPIA?
As person age, the natural lens in eye becomes less flexible. The lack of flexibility, called presbyopia, compromises the eye’s ability to switch from one focal point (e.g., distance) to another (e.g., near).
The practical effect of presbyopia is that a person loses the ability to read or see close objects without reading glasses or bifocals.
WHAT IS ASTIGMATISM?
In a healthy human eye, the cornea is round in shape like a basketball. Astigmatism occurs when the cornea is shaped more like a football. When light passes through a cornea with astigmatism, the image does not focus sharply on the retina, causing blurred vision.
THE TECHNOLOGY BEHIND THE TECNIS Symfony IOL
TECNIS Symfony Extended Range of Vision IOL is an advanced implantable lens, providing high-quality vision in any lighting condition, from near to far distances- and everything in between.
TECNIS Symfony Extended Range of Vision IOL uses two advanced technologies that work together to:
1. Elongate the focus of the eye to provide the extended range of vision.
2. Correct chromatic aberration (color distortion) to provide sharp vision in all lighting conditions.
IS PERSON VISION BLURRY OR CLOUDY?
ARE PERSONS BOTHERED BY HEADLIGHT GLARE WHEN DRIVING AT NIGHT?
If so, they may have cataracts.
Consultation is required to be sure whether the TECNIS Symfony Extended Range of Vision intraocular lens (IOL) may be the right choice for patient.
TECNIS Symfony IOL is the first and only presbyopia- correcting extended range of vision lens for patients with or without astigmatism.
EXTENDED RANGE OF VISION IOL
IS IT RIGHT FOR YOUR PATIENT?
TECNIS Symfony Extended Range of Vision lenses provide high quality vision from near to far, in all lighting conditions.
TECHNIS Symfony Extended Range of Vision IOL helps correct presbyopia, while TECNIS Symfony Toric Extended Range of Vision IOL helps correct astigmatism. Both lenses offer high spectacle independence at far, intermediate and near distances.
