What is a Cataract?
Eye Clinic in Morgantown, WV.
A cataract is a “clouding” of the eye’s natural lens. Which, results in blurred or defocused vision. Generally speaking, cataracts are often described as looking through wax paper or cloudy cellophane. More than 20 million adults in the U.S. have developed cataracts. Thus, making it the number one cause of poor vision in the United States. In most cases cataract surgery is required to improve an individual’s vision. The natural lens is replaced with a man made lens. Which, is often referred to as an IOL or intra ocular lens. This surgery is highly successful. And, is the most commonly performed surgery in the United States today.
Signs and Symptoms of a Cataract
In reality, the only way to properly diagnose a surgical cataract is to have an ophthalmologist perform a comprehensive, dilated eye exam. Most age related cataracts develop gradually. At the same time, just having a cataract does not necessarily mean that surgery is required. Surgery can be performed if the cataract is bad enough. Of course, if it is assessed by your surgeon. But also, if you have symptoms. As a result, you may not immediately notice changes in your vision when cataracts first develop.
In Time, You May Have Symptoms Such As:
- Clouded, blurry or dim vision
- Increased difficulty seeing at night or in low light
- Sensitivity to light and glare, seeing halos around lights
- Colors seem faded or yellowed
- The need for brighter light for reading and other activities
- Frequent changes in eyeglass or contact lens prescription
- Double vision within one eye
Causes of Cataracts
Cataracts occur as part of the natural aging process. So everyone is at risk eventually. By the age of 75, about 70% of people will have cataracts. The eye’s lens not only slowly becomes less flexible. But also, less transparent and thicker. Areas of the lens gradually become cloudy. Cataracts usually develop in both eyes at the same time.
These Factors Increase the Risk of Developing a Cataract
- Older age
- Family history
- Previous eye injury or inflammation
- Prolonged steroid use (especially combined use of oral and inhaled steroids)
- Extensive exposure to sunlight
Although cataracts have no scientifically proven prevention. It is sometimes said that wearing ultraviolet protective sunglasses may slow the development of cataracts. Regular intake of antioxidants such as vitamin A, C and E is theoretically helpful. Taking them as a supplement has been shown to have no benefit. The less well known antioxidant N-acetylcarnosine, has been shown in randomized controlled clinical trials. It is used to treat cataracts. Which, can be expected to prevent their formation by similar mechanisms. N-acetylcarnosine is a proposed treatment for other ocular disorders. These disorders are not only instigated or exacerbated by oxidative stress. But also, by glaucoma, retinal degeneration, corneal disorders and ocular inflammation.
