What Are Cataracts?

A cataract is a clouding of the natural lens inside your eye. This process occurs slowly over time. The lens, located behind the colored iris, works just like the lens of a camera, focusing light on the retina that sends images to the brain. The lens can become so clouded as it develops into a cataract that it prevents light and images from clearly reaching the retina.

Without treatment, cataracts can cause blindness. Early signs of cataracts can include:

  • Blurred vision
  • Faded or dull colors
  • Poor night vision
  • Sensitivity to light

A cataract can be the reason sharp objects become blurred, bright colors become dull, or seeing at night becomes more difficult. It may also be why your reading glasses or bifocals no longer seem to be effective.

Cataract removal means removing your clouded lens. It is one of the safest and most effective surgical procedures in medicine.

Cataract surgery is now a technologically advanced procedure performed with a tiny incision in the eye. Once the cloudy lens (cataract) is removed, it is replaced with a crystal clear, plastic replacement lens that is inserted through the same tiny incision. The new lens allows light to be clearly and precisely focused on the retina.

Fortunately, we live in a time when there are a wide variety of choices in cataract replacement lenses, and the ophthalmologists at the Mercyhealth Eye Center can achieve extraordinary results with cataract surgery.

It is now possible to achieve clear vision and be able to see near, far, and everywhere in between with little or no glasses or contact lenses. These premium lens implants offer the potential for an unprecedented visual recovery.
