“When the last prescription only helped for a couple of months, I knew I had to do something.

I wanted the latest technology. Now I can see lines more sharply. I see colors more vividly.” -TECNIS Symfony® IOL Patient

Understanding Your Vision


Cataract is a condition of the eye where the lens becomes cloudy, making images fuzzier. Your vision with cataracts is cloudy or dark in some areas or across your whole field of vision, and may cause:

  • Difficulty driving
  • Difficulty seeing at night
  • Difficulty viewing a computer screen, a phone or tablet
  • Colors to appear dim and faded
  • Frequent change in glasses prescriptions


In an eye with presbyopia, the natural lens has increasing difficulty focusing on intermediate and near objects. Light fails to reach a single point on the retina when viewing objects up close and instead focuses on a point behind the retina. Common symptoms may include:

  • Losing your ability to read up-close
  • Cloudier or fuzzier vision at near distance
  • Difficulty viewing a computer screen, a phone or tablet
  • Needing reading glasses or bifocals
  • Holding objects further away to read


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.

TECNIS Symfony® IOL is the first lens of its kind to combine two unique technologies for outstanding visual performance:

  • Elongating the focus of the eye to provide continuous, high-quality vision.
  • Correcting chromatic aberration (color distortion)  to provide sharp vision in all lighting conditions.

The Lens Designed for Everyday Life

Compare the following images. Image A demonstrates what you might see with a traditional implantable lens. Although distance vision is clear, notice how the phone screen, hand and near objects are very blurry.

Now compare that with Image B with  TECNIS Symfony® IOL. TECNIS Symfony® IOL provides high-quality continuous vision at any distance.

TECNIS Symfony® IOL provides continuous, high-quality vision at all distances and may allow you to wear glasses less often.


High-Quality Vision in Low-Light Conditions Your ability to see in dim light can define when, where, and how you’re able to spend your independent time. With TECNIS Symfony® IOL you may be able to comfortably enjoy low-light activities such as taking a walk at dusk, going to the movies, or even driving at night.

Nighttime Performance

With TECNIS Symfony® IOL, you may experience a loss of sharpness, which may become worse under poor visibility conditions such as dim light or fog. This may lead to difficulties in driving, and may cause problems such as not being able to detect hazards in the road as quickly at night or in fog. You may notice halos, starbursts, glare and other visual symptoms. This may impact your vision when there are bright lights at night.
