A cataract is clouding of the lens in your eye. This lens is normally clear, and allows light to pass through from the front of your eye to the retina so you can see. If the lens becomes cloudy, light cannot pass through and your vision becomes blurred. Most cataracts develop slowly. It is only in the later stages, when your vision becomes cloudy, that activities such as reading and driving can become difficult. Developing cataracts is a natural process of ageing that cannot be avoided or prevented with medicines.
There are several types of cataract:
1Causes
The most common cause of Cataract is ageing. As we age, some of the proteins in the lens may clump together and start to cloud a small area of the lens. Over time, the Cataract may grow larger and more of the lens becomes cloudy, making it harder to see. Some other causes of Cataract include:
2Symptoms
The first sign of Cataract is usually blurred vision. Other signs may include:
3Treatment
When your vision becomes impaired, you may need surgery to replace the lens. Not all people with cataracts need surgery. For some people, changing their glasses or using a magnifying glass may improve their vision sufficiently.
If you do need surgery, cataract surgery is usually performed as day surgery under local anaesthetic. By using the latest technology, we are able to offer bladeless cataract surgery. In this procedure, the incisions for the surgery are made by laser rather than a surgical blade, which makes the surgery more accurate.
4Complications &
Related Diseases
Cataract surgery is normally safe and most patients heal well with good vision. Infection may sometimes occur and can result in poor vision. Warning signs of infection include:
If you notice any of these signs, you should see your eye doctor immediately.
Some other complications are retinal tear and/or detachment, and bleeding.
