Are there different types of cataracts




















Children can get cataracts, too. They can be born with cataracts congenital cataracts , or develop them later on. They can also happen because of serious complications during pregnancy or because of illnesses during childhood, like uveitis or tumors in the eye.

Children can also get cataracts for the same reasons as adults — eye injuries, radiation, or steroid medications. When pediatric cataracts are large enough to cause vision problems, they need immediate treatment. After cataract surgery, some people may develop a condition called secondary cataract that makes their vision cloudy again. This condition is also called after-cataract or posterior capsule opacification. During cataract surgery, your doctor removes the lens from your eye and replaces it with a clear artificial lens.

Make an appointment for an eye exam if you notice any changes in your vision. If you develop sudden vision changes, such as double vision or flashes of light, sudden eye pain, or sudden headache, see your doctor right away.

Most cataracts develop when aging or injury changes the tissue that makes up the eye's lens. Proteins and fibers in the lens begin to break down, causing vision to become hazy or cloudy. Some inherited genetic disorders that cause other health problems can increase your risk of cataracts.

Cataracts can also be caused by other eye conditions, past eye surgery or medical conditions such as diabetes. Long-term use of steroid medications, too, can cause cataracts to develop. A cataract is a cloudy lens. The lens is positioned behind the colored part of your eye iris.

The lens focuses light that passes into your eye, producing clear, sharp images on the retina — the light-sensitive membrane in the eye that functions like the film in a camera.

As you age, the lenses in your eyes become less flexible, less transparent and thicker. Age-related and other medical conditions cause proteins and fibers within the lenses to break down and clump together, clouding the lenses. As the cataract continues to develop, the clouding becomes denser. A cataract scatters and blocks the light as it passes through the lens, preventing a sharply defined image from reaching your retina.

As a result, your vision becomes blurred. Cataracts generally develop in both eyes, but not always at the same rate. The cataract in one eye may be more advanced than the other, causing a difference in vision between eyes.

These fissures can cause the light that enters the eye to scatter, creating problems with blurred vision, glare , contrast, and depth perception. See Vision Changes Related to Cataracts for more information.
