What is Cataract?

Human eye has a clear natural lens. The lens is situated inside our eye, behind a soft tissue called iris. It can be easily seen through the central opening of the iris, called pupil. As we age, the natural lens loses its clarity, where the natural transparent lens fibers are replaced with opaque material due to oxidative stress. As a result, people with cataract will start to lose their eye sight, as if seeing through mist or clouds. If it is left untreated, it can cause blindness.

Cataract is the leading cause of blindness in the world, and aging is the commonest cause of cataract.


What causes Cataract?

There are many causes of cataract, but they can be broadly divided into congenital and acquired. Some inborn error of metabolism or hereditary disorder can cause congenital cataract but these are not common. Acquired etiologies include aging, ultra violet radiation from excessive exposure to sun (e.g: labourers) or welding sparks (e.g: metal/steel workers). Others include smoking, obesity, diabetes mellitus, eye injury, eye inflammation, eye surgery, hypertension and excessive usage of steroid based medications.

Cataract Symptoms

Cataract doesn’t occur overnight, because it starts as an insignificant change in your eyesight that gradually evolves. The first symptoms of cataract is loss of distance visual acuity and loss of contrast sensitivity. It occurs gradually, and some older people may not realize it until the cataract has reached the advance stage. Depending on the type of cataract, the visual presentations differ.

Some people may complain as if seeing through haze/ mist (cortical cataract), or some having severe glare when exposed to bright light condition (for example driving in a bright day light, or driving at night) (posterior subcapsular cataract) or some patient notices improvement in near reading abilities but loses the ability to see far (nuclear sclerosis). Nonetheless, all forms of cataract will cause loss of contrast sensitivity, and perception of colours will be dull and not as colourful as before.

If you have any of the above symptoms, please do not hesitate to seek for a professional eye specialist examination to rule out cataract. A correct diagnosis and treatment of cataract will improve your quality of life tremendously.

Not all cataract needs surgery with artificial lens implantation. When the cataract causes a mild shift in refraction, all you need to do is to get a new pair of glasses. However, you need to be aware that as the cataract progresses, the refraction power of your glasses will change and the old glasses may not be able to help you to regain your vision. At this stage, cataract surgery with artificial lens implantation is the only way for visual rehabilitation.
