WHAT IS CATARACT?

 ABOUT CATARACT

 A cataract occurs when the natural lens of the eye becomes cloudy. The normal natural lens is clear, and helps focus light on the retina in the back of the eye. As a cataract develops, it blocks and scatters light, reducing the quality of vision. Cataracts are part of the normal aging process. Most people over age 50 will have some degree of cataract, although some patients develop cataract at an earlier age or even at birth. Certain diseases (such as diabetes) or medications (such as steroids) can speed the development of cataracts

CATARACT SURGERY ?
In cataract surgery, the cloudy natural lens of the eye is removed. In almost all cases, the cataract is replaced with a clear artificial lens, called an intraocular lens implant (IOL), which is placed permanently inside the eye at the same time the cataract is removed. IOLs are available in different sizes, powers, materials, and designs, and must be selected by the surgeon depending on the needs of the eye

IS CATARACT SURGERY YOU?

The need for cataract surgery depends on your degree of vision impairment. If your vision is satisfactory and the symptoms caused by the cataract are not too bothersome, there is usually no need to undergo surgery right away. However, if the cataract is interfering with your work, lifestyle, or desired activities, keeping you from doing the things you want or need to do, then cataract surgery is indicated. In most cases, cataract surgery is considered an elective procedure, and the decision to have surgery is up to you, after evaluation and discussion with your surgeon. In some patients, a cataract can hinder the doctor's ability to see inside the eye and diagnose or treat problems behind the cataract, such as diabetes. Or, a cataract can become so large that it causes inflammation or uncontrollable glaucoma. In these unusual situations, cataract surgery may be advisable even if you are not bothered by the decrease in vision.
