Our eyes function very much like a camera. You have two natural lenses in each eye. One lens on the surface (cornea) of your eye, and a second lens within your eye, called the crystalline lens. Together these lenses focus images inside the back of your eye on the retina. At birth, our crystalline lens is clear. As we begin to age, it yellows and begins to harden. When it becomes cloudy, it is defined as a cataract and begins to interfere with the quality of our vision.
Everyone at some point will develop cataracts with age. Symptoms of cataracts include images becoming blurred, bright colors becoming dull, and seeing at night becoming more difficult. It may also be the reason your glasses do not seem to help keep things in focus as well as they used to. As a cataract begins to develop over time, people tend to accept and adjust to the decline in their lifestyles.
Lens replacement surgery is the only way a cataract can be removed. This surgery involves a very small incision through which the natural crystalline lens is removed. Once the lens is removed, it is simply replaced with a new artificial lens that provides clear vision. The time to consider lens replacement surgery is when you are no longer satisfied with your vision or the quality of your vision begins to put limits on your lifestyle. With advancements in technology, you now have choices of what type of lens will be used for your lens replacement surgery, and recovery is more swift.
