A cataract is caused by a clouding of the natural lens inside the eye. Normally, light rays are focused through your lens and onto the retina, a layer of light-sensitive cells in the back of the eye. Over time, the lens can become cloudy and prevent light rays from reaching the retina. The result is blurry or distorted vision. Cataracts generally develop slowly and painlessly. In fact, you may not even realize that your vision is changing. In its early stages, vision blurred by a cataract can be improved with glasses or contact lenses. However, it is important to note that glasses, contact lenses, dietary changes or laser treatments cannot make the cataract go away. The only way to remove a cataract is through surgery.
Over the years, there have been numerous advances in the technology for removing cataracts. These improvements have made cataract treatment surgery one of the safest procedures performed today, and have significantly shortened the recovery time. Millions of people undergo this vision-improving procedure every year and experience excellent results.
