Cataracts: Discover the Options for Your Surgery
Time to ask yourself:
- Is your vision blurry or foggy?
- Do colors appear dull or muted?
- Are your glasses no longer working?
- Does sunlight or other light seem overly bright or glaring?
- Do you have decreased night vision or see halos around lights?
If you experience one or more of these symptoms, you may have cataracts, a clouding of your eye’s natural lens that affects many of us as we age. Cataracts are the leading cause of visual loss in adults 55 and over. Fortunately, we live in a time when correcting cataracts is relatively simple and the results can be extraordinary. With today’s advances, some patients enjoy the best vision of their lives.
How We See
Our eyes work just like a camera. When we look at an object, light rays reflect off that object and enter our eyes through the cornea. The lens behind the cornea focuses the rays onto the retina which, in turn, converts the rays into electrical impulses that travel through the optic nerve to the brain. The brain converts the electrical impulses into images. Seeing depends on this entire chain of events. But seeing clear, focused images depends largely on the lens.
Cataracts Are a Natural Part of Aging
Cataracts are the leading cause of visual loss in adults 55 and over. A cataract is a clouding of the natural lens inside your eye. This lens, located behind the iris, works just like the lens of a camera — focusing light images on the retina, which sends images to the brain. The human lens can become so clouded it prevents light and images from reaching the retina. A cataract can be the reason sharp objects become blurred, bright colors become dull, or seeing at night is more difficult. It may also be why reading glasses or bifocals that used to help you no longer seem to be effective.
Vision with cataracts has been described as seeing life through old, cloudy film. But a cataract is not a “film” over the eye, and neither diet nor lasers will make it go away. Nor can it be prevented. Eye injury, certain diseases, or even some medications can cause clouding, but the majority of cataracts are simply a result of the natural aging process. The best way to treat a cataract is with cataract surgery that removes the old, clouded lens and replaces it with a new, artificial one to restore your vision and, in many ways, significantly improve your quality of life.Back to Top
