According to the World Health Organization, there are about 18 million people that show cataract symptoms, which accounts for over half the world’s blindness. A cataract on a person’s eye looks like a white cloud or liquid that obstructs the person’s view. This white milky substance forms in the eye lens, which is the part of the eye that helps focus the light coming into the retina, the light-sensitive wall of tissue at the back of the eye.
Cataracts are more likely to form in people as they age, affecting more than half of senior citizens over the age of 70, but can occur in children as well. Without cataract treatment, a person will inevitably go blind in the affected eye. Some of the most common cataract symptoms are:
1. Cloudy or blurred vision, with an inability to focus.
2. Faded colors of images.
3. Any light appearing too bright and any source of light having a surrounding halo. Night vision also suffers dramatically.
4. Double or multiple vision.
There are different cataract types. Secondary cataracts develop as an effect of illnesses such as diabetes and can form after surgical procedures. Injuries to the eye can result in traumatic cataracts. While older people are more prone to cataracts, congenital cataracts can be found in new-born babies. Radiation cataracts can develop in people who have been exposed to harmful amounts of radiation. These different cataract types affect different people, but their effect is devastating if left untreated.
When cataracts form in a person, cataract treatment is required. When a cataract is in its early phases, it can still be prevented by taking care of the eyes or using corrective lenses. However, if nothing works and the cataracts keep forming, surgery is the only option left. This would involve removing the affected lens and replacing it with an artificial one.
As with any other surgery, there are risks involved, but, delaying cataract surgery will only cause more damage to your eye and make future cataract treatment even more difficult. When this happens, it is best that you consult with your eye care professional, who will help you understand the benefits and risks of having surgery.
