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.

Think about surgery when your cataracts have progressed enough to seriously impair your vision and affect your daily life. Many people consider poor vision an inevitable fact of aging, but cataract surgery is a simple, relatively painless procedure to regain vision.

A cataract is the clouding of your lens, the part of the eye that helps you focus on near and far objects. This causes double vision (diplopia) and blurred images. Cataracts occurs because of a build up of dead cells and oxidation. The only way to treat cataracts is by surgery,The cataract is situated inside the lens capsule, which is like an elastic bag that holds the lens in place. To remove the cataract, the front portion of the lens capsule is carefully opened. The cataract is gently broken apart using ultrasonic vibrations and vacuumed out of the lens capsule. This technique is called phacoemulsification. The lens capsule is left undisturbed so a tiny lens implant can be inserted in place of the original lens.

Answer 4

a cataract is any opacity which develops in the crystalline lens of the eye or in its envelope. The name derives from the Latin cataracta meaning "waterfall" and the Greek kataraktes and katarrhaktes, from katarassein meaning "to dash down" (kata-, "down"; arassein, "to strike, dash") [1].

Cataracts form for a variety of reasons, including long-term ultraviolet exposure, secondary effects of diseases such as diabetes, or simply due to advanced age; they are usually a result of denaturation of lens proteins. Genetic factors are often a cause of congenital cataracts and may also play a role in predisposing someone to cataracts. Fully half of all people between the ages of 65 and 74 and about 70% of those over 75 have some cataract formation. Cataracts may also be produced by eye injury or physical trauma. A study among Icelandair pilots showed commercial airline pilots as three times as likely to develop cataracts as people with non-flying jobs. This is thought to be caused by radiation coming from outer space [2].

Cataracts may be partial or complete, stationary or progressive, hard or soft.

Answer 5

cataract is a clouding of the lens of the eye. the lens is a clear disc within the eyeball. it is normally transparent & is situated behind the pupil. a cataract is like a dirty or cloudy camera lens. a cataract is neither a tumor nor an abnormal growth of tissue in the eye. it is due to physical changes in the contents of the lens, resulting in clouding. it is easily detected with specialised instruments by used doctors. surgery is the only effective way to remove a cataract.
