What is a Cataract?
The natural lens of the eye helps to focus light on the retina inside the eye to produce clear images. A cataract is a clouding of the eye’s natural lens as people age. A cataract can also be caused from an eye injury, certain diseases, certain medications or long-term exposure to sunlight. It is one of the leading causes of vision loss in the United States.
A cataract can be the reason that objects become blurred, bright colors seem dull, or seeing at night becomes more difficult. Occasionally, changing your eyeglass prescription may help to improve your vision for a while. When you can no longer see well enough to do the things you like to do, cataract surgery should be considered to improve your vision. To determine if your cataract should be removed, your ophthalmologist will perform a thorough eye examination.
In cataract surgery, the cloudy lens is removed through a tiny incision. After the cataract is removed, the natural lens is replaced with a permanent lens, called an intraocular lens implant (IOL). These IOLs come in different focusing powers. At your evaluation, your eyes will be measured to determine the proper focusing power of the IOL for your eyes. Different IOL options are available to help give you the best vision to complement your own individual lifestyle.
