Cataracts occur as part of the normal aging process. Studies show that virtually everyone over age 65 has some cataract formation in their eyes! Cataracts can severely reduce your vision. At one time, cataracts were a leading cause of blindness in the world. But today, fortunately they can be treated. Modern surgical techniques, intraocular lens implantation and "same day surgery" make cataract surgery safe, fast and effective.

A cataract occurs when the normally clear lens of the eye becomes cloudy. As the cataract develops, the cloudiness no longer allows the lens to properly focus light on the back of the eye. This unfocused light causes the vision to look blurry or hazy. Development of cataracts has been associated with exposure to ultraviolet radiation. They are particularly prevalent in persons who spend a lot of time in the sun, such as fisherman. There is nothing you can do to prevent the formation of cataracts.

Cataract treatment is advised when decreased vision affects your everyday activities or hobbies.

Cataract surgery, in which the normal cloudy lens is removed, is now a very successful procedure. The most widely used technique is called phacoemulsification. A very small incision is made and a tiny ultrasonic probe is used to break up the cataract and gently suction it away. A clear membrane is left in your eye where an intraocular lens is placed (IOL). This IOL is necessary to replace the focusing power of the natural lens, which was removed. With insertion of an IOL, there is little need for thick cataract glasses and contact lenses that were used years ago. Other type of lenses gaining popularity are MULTIFOCAL and ACCOMODATIVE. These IOLs may be used to treat myopia, hyperopia and presbyopia, and may allow less reliance on glasses and/or contact lenses to see clearly at both distance and near.

Small incision surgery has several benefits. The procedure is very quick, sometimes taking less than 20 minutes. Also, recovery time is short. The results of the surgery are almost immediate. Most people notice an improvement in their vision soon after surgery.
