Cataract
Dr Seah is trained in the latest techniques of phacoemulsification and these surgeries are mostly performed only under topical anaesthesia employing the sutureless technique. On top of that, he is trained to handle the more complex cataract cases such as those with small pupil, shallow anterior chamber, and dislocated lenses. He have performed an estimated number of 17,000 – 18,000 cataract surgeries since 1987. His quality assurance results is close to 100% with complication rate less than 0.3%.
WHAT IS CATARACT?
A cataract is a clouding of the eye's natural lens which impedes the passage of light, causing a decrease in the vision. It is the most common cause of vision loss in people over the age of 40, and is the prinicipal cause of blindness in the world.
The lens is made of mostly water and protein. The protein is arranged in a precise way that keeps the lens clear, allowing light to pass through it to focus a clear image. As we age, this protein begins to break down and clump together, and start to cloud a small area of the lens which forms cataract. Over time, the cataract may become denser, making it more difficult to see.
Most cataracts are related to ageing, other causes of cataract may include injury, inflammation, disease. Occasionally children may be born with the condition too.
