A cataract is a clouding of the eyes natural lens that makes it difficult for patients to see clearly.  Cataracts interfere with light passing through to the retina, causing patients to have blurry or cloudy vision.  Cataracts grow very quickly for some patients, while for others it takes more time for the cataracts to mature.    There are three main types of cataracts. A subcapsular cataract occurs at the back of the lens.  Patients with diabetes have a greater risk of developing this type of cataract. A nuclear cataract forms deep in the nucleus or central zone.  These are usually associated with aging. A cortical cataract is a white, wedge like opacity that starts in the periphery of the lens and work their way to the center in a spoke-like fashion.  This type of cataract occurs in the lens cortex.   You may be able to improve your vision for a while using a pair of prescription eyeglasses.  Once your vision is impaired to the point that it affects your daily life, surgery is recommended.  Cataract surgery is very successful in restoring vision. During the surgery, the surgeon will remove your clouded lens and replace it with a clear, plastic intraocular lens, otherwise known as an IOL. New IOLs are being developed all the time to make the surgery less complicated for surgeons and the lenses more helpful to the patient.
