What is Cataract?
A cataract is a loss of transparency, or clouding, of the normally clear lens of the eye. As one ages, chemical changes occur in the lens that make it less transparent. The loss of transparency may be so mild vision is hardly affected or so severe that no shapes or movements are seen, only light and dark. When the lens gets cloudy enough to obstruct vision to any significant degree, it is called a cataract. There are over 1 million cataract surgeries performed annually in the USA. It is an outpatient procedure with a very high success rate. Due to the lack of modern medical technology in the developing world, it is also the world’s leading cause of blindness. Over 16 million people are blind from cataracts.
Cataract Surgery
During the surgery, the cloudy natural lens is removed from the eye. In most cases, the focusing power of the natural lens is restored by replacing it with a permanent intraocular lens (IOL) implant. When to have a refractive correction surgery done is often a subjective decision, based on how well you are able to see while engaging in routine activities. You might be able to drive, watch television and work at a computer for quite a few years, even after you are first diagnosed with a refractive difficiency. However, you may eventually start to notice “ghost” images and declining visual clarity, which can’t be corrected with glasses or contacts. Colors may also begin to look faded. If your functional vision is impaired significantly and it becomes difficult for you to visually perform your normal daily activities, it may be time for cataract surgery.
