As the cataract grows, the clouding becomes worse. A cataract scatters and blocks the light as it passes through the lens. This prevents a clearly defined image from reaching your retina. As a result, your vision becomes blurred. Cataracts usually happen in both eyes, but not always at the same rate. The cataract in one eye may be worse than ...
During cataract surgery, an ophthalmologist removes your clouded natural lens and replaces it with an intraocular lens (IOL). An IOL is an artificial lens that permanently stays in your eye.
A cataract is when your eye's natural lens becomes cloudy. Proteins in your lens break down and cause things to look blurry, hazy or less colorful. We are all born with a natural lens inside each of our eyes. The lens bends (refracts) light rays that come into the eye to help us see.
Discover what cataracts are, why they develop, symptoms to watch for, and how modern cataract surgery can help you regain clearer vision.
Cataract formation is primarily driven by oxidative stress, which damages lens proteins, leading to their aggregation and the accumulation of clumps of protein or yellow-brown pigment in the lens. [10] This reduces the transmission of light to the retina at the back of the eye, impairing vision.
If your child’s cataract is small and doesn’t affect their vision, it may not need to be removed. But if it does affect their eyesight, it should be treated as soon as possible.
A cataract is a cloudy area in the lens of your eye. More than half of all Americans age 80 and older either have had cataracts or have had surgery to get rid of cataracts. Learn about the types, symptoms, and causes of cataracts and how your doctor will diagnose and treat them.
Common cataract symptoms include gradual blurry vision, glare from lights, trouble seeing at night, and reduced color clarity. Recognizing these symptoms early can help you manage your vision proactively. That’s why regular comprehensive eye exams are essential.
