A cataract is a clouding process that occurs in all or part of the eye lens. The cause of cataracts are due to aging, accidents, impaired metabolism due to prolonged illness, congenital or even poisoning. Symptoms experienced by patients with cataract is a clouding of vision, glare, when viewed with the aid of light on the pupil will look cloudy. Cataracts are divided into several types:
1. Senile cataract (aging). namely cataracts that arise after the age of 40 years, the process is not known, allegedly due to aging.
2. Congenital cataracts. namely cataracts that arise in the womb or after birth arise, usually caused by an infection, and metabolic disorders in the formation of the fetus. Congenital cataracts are often caused by an infection during pregnancy, especially in the first 3 months of pregnancy.
3. Cataracts Traumatika. namely cataracts that can strike all ages, it is usually due to either posttraumatic sharp or dull, especially on the lens of the eye.
4. Complicated cataract, cataract is incurred after eye infection.
Cataract Treatment
Cataracts can be treated with surgery the cloudy lens collection. There are several surgical techniques performed in the hospital, namely: Operations with sliced wide with conventional sutures and with a small incision without sutures removed with tools Phaceomulsifikasi lens (small incision surgery).
Selection of surgical technique depends violence eyepiece. Once the cataract lens is taken, the patient can only count fingers at a distance of 1 meter, unless the patient replaced the lens.
Replacement lenses there are two ways:
* Patients after surgery were positive eyeglasses or contact lenses for about 10 diopters.
* Patients with a lens mounted planting coincided surgery, the advantage is the patient after surgery patients can immediately see clearly, do not need to wear very thick glasses, the patient remained wide field of vision and light distortion can be eliminated.
There are three types of cataracts, which are:
1. Nuclear. Cataracts occur lens center. In the early stages there will be changes in the focusing of light. For a while you will progress especially in reading vision. But then the vision will form formed yellow and white stain on the lens. Furthermore eyesight will deteriorate vision Becomes brown. In the severe stage would be difficult to distinguish colors Because The view would be blue or purple.
2. Cortical. Cataract formation is initiated by the stains on the outer layer of the eye. This process is slow. Then stain may spread to the central part of the lens and interfere with the flow of light into the center of the lens. People with this type of cataract will experience glare when looking at the light.
3. Subcapsular. This type of cataract formation begins with the area under the lens opaque. Cataracts are usually formed behind the lens that is the path of light to the retina. Cataracts often affect the ability to read, reducing the ability to see in bright light and cause glare or halos when looking at the light at night.
