We can say that certain types of cataracts progress quite rapidly and cause cloudy vision within a few months. Fortunately, these are relatively uncommon. Most cataracts develop gradually and do not require surgery for many months or years. Cataract surgery is rarely painful and most patients who have gone through the procedure say they only had slight discomfort. After surgery, most patients are relieved how fast and relatively pain-free the procedure is.
We know that a cataract is a dense, cloudy area that forms in the lens of the eye. A cataract begins when proteins in the eye form clumps that prevent the lens from sending clear images to the retina. The retina works by converting the light that comes through the lens into signals. Most cataracts develop when aging or injury changes the tissue that makes up your eye's lens. Some inherited genetic disorders that cause other health problems can increase your risk of cataracts. Cataracts can also be caused by other eye conditions, past eye surgery or medical conditions such as diabetes.
