Eye for an Eye: How to Counteract Cataracts Hartwell GA

As people in Hartwell age, there are certain medical issues that they can practically bank on, and one of them is cataracts, or a clouding of the lens of the eye. If you're middle-aged and you're finding it difficult to take afternoon walks on sunny days because of the glare, or if the TV screen has started blurring even when you're wearing glasses, you may have cataracts.

As people age, there are certain medical issues that they can practically bank on, and one of them is cataracts , or a clouding of the lens of the eye. If you're middle-aged and you're finding it difficult to take afternoon walks on sunny days because of the glare, or if the TV screen has started blurring even when you're wearing glasses, you may have cataracts.

According to the National Eye Institute, almost 20.5 million Americans aged 40 and over have cataracts, and more than half of Americans have cataracts by the time they are 80. As a result, more than 1.4 million cataract surgeries, in which the cloudy lens is replaced with an implant, are performed in the United States each year. Below, Penny A. Asbell, MD, a professor of ophthalmology at Mount Sinai School of Medicine in New York City, talks about the timing of cataract surgeries and improvements that have helped make this surgery so successful.

What are cataracts?

Inside the eye is a lens like a lens in glasses. If that lens gets cloudy, we change its name from lens to cataract. So a cataract is a cloudy lens inside the eye.

What causes cataracts?

We know that some diseases are associated with cataracts, such as diabetes, and that some drugs can cause cataracts, such as steroids or prednisone. Exposure to ultraviolet light causes a kind of cataract. But in general, we see an increased incidence of cataracts as we age. So it's one of those things that happens to almost everybody if they live long enough.
