What is Cataract?

If your vision has become blurry, cloudy or dim, or things you see are not as bright or colorful as they used to be, a cataract may have developed in one or both of your eyes. Many people say that their vision with cataracts is similar to the effect of looking through a dirty car windshield.

EYE CS CataractsAs a cataract slowly begins to develop, you may not notice any changes in your vision at first.  But as the cataract progresses, you may begin to find that it interferes with your daily activities.  Performing a complete eye exam, our ophthalmologist can tell you whether cataract or another problem is the cause of your vision loss.

While cataracts are one of the most common causes of vision loss, especially as we age, they are treatable with cataract surgery. Since most cataracts are part of the normal aging process, they cannot be reversed.  There are no medications or eye drops that will make cataracts go away—surgery is the only treatment.

A cataract may not need to be removed right away if your lifestyle isn’t significantly affected.  In some cases, simply changing your eyeglass prescription may help to improve your vision. Contrary to popular belief, a cataract does not have to be “ripe” to be removed. However, once you are diagnosed with a cataract, your ophthalmologist needs to monitor your vision regularly for any changes.

Cataract Surgery for Clearer Vision

When a cataract causes bothersome vision problems that interfere with your daily activities, our ophthalmologist may recommend surgery to remove the cataract. With cataract surgery, your eye’s cloudy natural lens is removed and replaced with a clear artificial lens implant (called an intraocular lens or IOL).

Cataract Risk Factors

These factors increase your risk of developing cataracts:

•   Advanced age;
•   Diabetes;
•   A family history of cataracts;
•   Extensive exposure to sunlight;
•   Smoking;
•   Obesity;
•   High blood pressure;
•   Previous eye injury or inflammation (swelling) in the eye;
•   Previous eye surgery;
•   Long-term use of steroid medication (especially combined use of oral and inhaled steroids).

If you have any of these risk factors for cataract, you should schedule an appointment with your ophthalmologist.

Cataract by elderly (aging)

EYE CS Cataracts 2 EyesThe lens is made mostly of water and protein. As we age, the lens continues to grow layers on its surface and hardens. Protein in the lens may clump together and become cloudy in some areas, preventing light from passing clearly through the eye. This cloudiness of the lens is what we call a cataract.

If the clouding is mild or only involves a small part of the lens, your vision may be only slightly affected. If there is more clouding and it affects the entire lens, your vision will become severely limited and cataract surgery becomes necessary.

Congenital or developmental cataracts

This type of cataract can occur in infants or children. They may be hereditary or they can be associated with some birth defects. Some occur without any obvious cause.

Non-age related cataracts from other disease or medication

These cataracts are caused by other eye diseases or previous eye surgery. Chronic disease, such as diabetes, or excessive use of steroid medications can spur development of this type of cataract.

Traumatic cataracts

These cataracts are related directly to an eye injury. Traumatic cataracts may appear immediately following injury, or they can develop several months or even years later.

Cataract Treatment

With cataract surgery, your eye’s cloudy natural lens is removed and replaced with a clear artificial lens implant (called an intraocular lens, or IOL). Your ophthalmologist will discuss the cataract surgery procedure, preparation for and recovery after surgery, the benefits and possible complications of cataract surgery, cataract surgery costs and other important information.

Cataract surgery is often performed as an outpatient procedure and does not require an overnight hospital stay.
