Answer 1

What is a cataract?

A cataract is a clouding of the lens in the eye that affects vision. Most cataracts are related to aging. Cataracts are very common in older people. By age 80, more than half of all Americans either have a cataract or have had cataract surgery.

A cataract can occur in either or both eyes. It cannot spread from one eye to the other.

What are the different types of cataract surgery?

There are two types of cataract surgery. Your doctor can explain the differences and help determine which is better for you:

Phacoemulsification, or phaco. A small incision is made on the side of the cornea, the clear, dome-shaped surface that covers the front of the eye. Your doctor inserts a tiny probe into the eye. This device emits ultrasound waves that soften and break up the lens so that it can be removed by suction. Most cataract surgery today is done by phacoemulsification, also called "small incision cataract surgery."

Extracapsular surgery. Your doctor makes a longer incision on the side of the cornea and removes the cloudy core of the lens in one piece. The rest of the lens is removed by suction.

After the natural lens has been removed, it often is replaced by an artificial lens, called an intraocular lens (IOL). An IOL is a clear, plastic lens that requires no care and becomes a permanent part of your eye. Light is focused clearly by the IOL onto the retina, improving your vision. You will not feel or see the new lens.

Some people cannot have an IOL. They may have another eye disease or have problems during surgery. For these patients, a soft contact lens, or glasses that provide high magnification, may be suggested.

Answer 2

Contrary to popular belief, Cataract is not caused by eye strain or reading too much, but is a result of aging, injury, steroid use, exposure to UV light, smoking & diabetes. Almost every person develops cataract changes as the eye ages. It is a natural process of eye aging.

WHAT IS A CATARACT?

The term cataract is used to describe the clouding of the natural lens of the eye. The vision dims because the cataract prevents light from passing beyond the lens and focusing on the retina.

Answer 4

no it actually isnt a foreign particle rather due to aging/injury a white cloud forms over the eye

Answer 5

A cataract is an opacity of the lens that is inside the eye. It is kind of like when a window goes frosty.

You can see a video of cataract surgery (where the inside of the lens is removed and replaced by an artificial lens).
