What is a Cataract

A cataract is a clouding of your eye’s lens. The clouding usually develops over time and interferes with light entering your eye affecting your ability to see clearly.

If left untreated, cataracts may progress and eventually cause you to go blind. Both eyes may be affected, although not usually to the same extent. The risk of getting cataracts increases with age and may cause the following symptoms to your vision:

    • Blurriness and ghosting of images
    • Glare with sunlight or car headlights
    • Difficulty with driving or reading in one or both eyes.



Cataract facts

    • Cataracts are mainly diagnosed in people over 60 but can occur at any age (some babies may even be born with them).
    • Age is the major risk factor for developing cataracts.
    • A cataract can also be associated with eye trauma, prolonged use of steroids, previous inflammation and infection in the eye, diabetes and other systemic diseases.
    • A cataract starts out small at first and has little effect on your vision.


What Causes Cataracts

The lens inside your eye is mostly made up of water and protein. The lens, focuses light onto the retina for clear vision and adjusts the focus so you can see things clearly up close and further away.

The protein in your eye is arranged in a precise way that keeps the lens clear and lets light pass through it.

As you age, some of the protein may clump together and start to cloud a small area of the lens. This is a cataract, and over time, it may grow larger and cloud more of the lens, making it harder to see.

No one knows for sure why the eye’s lens changes as we age, forming cataracts. But researchers worldwide have identified factors that may cause cataracts including:

    • Advancing age
    • Ultraviolet radiation from sunlight and other sources
    • Diabetes
    • Smoking
    • Prolonged use of corticosteroid medications
    • Previous eye injury/surgery or inflammation
    • Family history.

Cataract Treatment

At first when cataracts symptoms appear, you may be able to improve your vision for a while using:

    • New prescription glasses or contact lenses
    • Bifocal glasses
    • Magnification devices
    • Appropriate lighting or;
    • Other visual aids.

Cataract surgery

Surgery is an option when your cataracts have progressed enough to impair your vision and affect your daily life. In most cases cataract surgery is a relatively painless procedure that has a high success rate to help regain vision.

Cataract surgery involves replacing the dysfunctional (cloudy) lens with an artificial one. Your surgeon will remove your clouded lens and in most cases replace it with a clear, plastic intraocular lens (IOL).

The surgery usually takes around 10 minutes.
