What is a Cataract?

11A cataract is a clouding of the natural lens in side your eye. This lens, located behind the colored iris, works just like the lens of a camera-focusing light on the retina, which in turn, sends images to the brain. The human lens can become so clouded with a cataract however, that it keeps light and images from reaching the retina.

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

Vision with cataracts has been described as seeing life through an old, cloudy film. But cataracts are not a “film” and neither diet nor laser will make it go away or prevent it. Eye injury, certain diseases or even some medications can accelerate the process but, a majority of cataracts are simply a result of ageing. The most common way to treat a cataract is with surgery to replace the old, clouded lens with a new, artificial one called an Intraocular Implant.
