WHAT IS A CATARACT?
Cataract is a condition in which the clear lens of the eye becomes cloudy, preventing sufficient light rays from entering the eye and impairing vision.
WHAT CAUSES CATARACT?
- It is common in the elderly due to ageing. Over 80% of people aged 60 and above have some form of cataracts.
- Prolonged ultra-violet light exposure.
- Long-term use of medications such as steroids and certain illnesses like diabetes are also risk factors for the development of cataracts.
- In the young, cataract can be present at birth or develop as a result of injury.
WHAT ARE THE SYMPTOMS OF CATARACT?
- Blurring of vision.
- Colors appearing dull.
- Poor vision in bright light.
- Difficulty reading or watching television or driving a night.
- Light sensitivity (glare).
HOW IS CATARACT DIAGNOSED?
Your eye doctor will be able to diagnose your cataract from clinical examination when you visit the clinic.
HOW CAN CATARACT BE PREVENTED?
There is no scientifically proven prevention. However, you can look after your eyes by protecting then from ultra-violet light by wearing sunglasses regularly, eating a balanced diet, treating diseases such as diabetes, and refrain from smoking.
HOW IS CATARACT TREATED?
- Cataract can be treated by surgery that involves making a small incision of 1.8 to 3.0 millimeter on the cornea (transparent front part of the eye).
- A vibrating instrument is introduced into the eye through the small wound. It soften the affected lens, which is taken out through the same instrument at the same time.
- An artificial lens will be then implanted to replace the removed lens.
- The surgery is completed without any need for stitches.
