Understanding Cataract

What is Cataract?

A cataract is a progressive, painless clouding of the natural, internal lens of the eye. Just like how a camera lens work when focusing images onto film for a clearer picture, our natural lens focuses images onto the back of our eyes so that we can see clearly. Our natural lens are clear at birth but will gradually turn “yellow” over time as we age, the lens may begin to gradually become “cloudy”. This formation of “cloud” is called a cataract and is often a result of the natural aging process. 

If you experienced one or more of these symptoms listed below, you may have cataracts;

How is cataract treated?

While new eyeglasses, brighter lighting, anti-glare sunglasses or magnifying lenses does improve the symptoms of early cataract, a surgery is the only effective treatment for a cataract patient. A cataract needs to be removed only when vision loss interferes with your everyday activities, such as driving, reading or watching TV. 

Phacoemulsification, or phaco is a surgical method to remove cataract from patient. A small incision is made on the side of the cornea, the clear, dome-shaped surface that covers the front of the eye. The specialist will then insert a tiny probe into the eye. This device emits ultrasound waves that soften and break up lens so that it can be removed by suction. Most cataract surgery today is done by phacoemulsification. 

By having your vision tested regularly, you and your ophthalmologist can discuss if and when you might need treatment.
