cataracts, the eye disease

Cataract is a clouding in the lens of the eye that causes visual impairment. Most of the lens a bit cloudy after 60 years of age. Most of the patients experienced similar changes in both eyes, although changes in one eye may be worse than the other eye.

Risk Factors
Cataracts usually occur in old age and could be lowered. Cataract formation is accelerated by environmental factors, such as smoking or other toxic materials.

Pathophysiology
All rays entering the eye must first pass through the lens. Therefore, every part lenses that block, deflect or spread the beam can cause vision problems.
Severity of visual impairment depends on the location and maturity of the cataract. Cataracts develop slowly and do not cause pain accompanied by vision problems that emerge gradually.

Symptoms and Signs
Complaints are often felt by sufferers is the lack of vision and murky picture of the eye. Vision problems can include difficulty seeing at night, saw the circle around the light or the light was blinding, decreased visual acuity (even during the day), frequently changing eye glass, and double vision in one eye.

Prevention
Primary prevention is to control diseases associated with cataracts and avoiding the factors which accelerate cataract formation.
Using sunglasses when outdoors during the day can reduce the amount of ultraviolet rays that enter the eye. Quitting smoking can also reduce the risk of cataracts.

Management
The only treatment for cataracts is surgery. Surgery is performed if the patient can not see well with the help of glasses to perform daily activities. Some patients may feel better eyesight simply by replacing his glasses, eye glass bifokus using a more powerful or use a magnifying lens. If the cataract does not interfere with surgery is usually not necessary.
Cataract surgery is often performed and generally safe. After surgery are rare infection or bleeding in the eye that can lead to serious vision problems. To prevent infection, reduce inflammation and speed healing, for several weeks after surgery are given eye drops or ointment.
To protect the eyes from injury, patients should use protective eye glasses or made of metal until the surgical wound is completely healed.
