Cataract: A Problem to be Addressed


Cataract is a common eye problem that affects millions of people worldwide. It occurs when the natural lens of the eye becomes cloudy, resulting in blurry vision, glare, and difficulty seeing in low light conditions. Although cataracts are usually associated with aging, they can affect people of all ages, including infants and young children. If left untreated, cataracts can lead to blindness. In this blog, we will discuss cataracts, their causes, symptoms, diagnosis, treatment, and prevention.

Causes of Cataracts

There are several causes of cataracts, including aging, injury, genetics, and certain medical conditions. The most common cause of cataracts is aging. As we get older, the proteins in the lens of our eyes begin to break down, causing cloudiness and opacity. Other factors that can contribute to cataracts include exposure to UV radiation, smoking, and certain medications.

Symptoms of Cataract

The symptoms of cataract can vary depending on the severity of the condition. Some people may experience mild symptoms, while others may experience more severe symptoms. Common symptoms of cataracts include blurred or cloudy vision, sensitivity to light, difficulty seeing at night, halos around lights, and a need for brighter light to read or perform other tasks.

Diagnosis of Cataracts

Cataracts are usually diagnosed during a comprehensive eye exam. During the exam, an eye doctor will examine the lens of the eye for cloudiness or opacity. They may also perform other tests, such as a visual acuity test, to determine the severity of the cataract and its effect on vision. If a cataract is detected, the doctor will discuss treatment options with the patient.

Treatment of Cataract

The treatment of cataracts typically involves surgery, as it is the most effective way to address this condition. During cataract surgery, an eye surgeon removes the clouded lens and replaces it with an artificial lens. The surgery is usually performed on an outpatient basis, and patients are given local anesthesia to numb the eye.


During the surgery, the surgeon makes a small incision in the eye and uses ultrasound technology to break up the cloudy lens into small pieces. Then, they suction out the pieces of the cloudy lens from the eye. The surgeon inserts an artificial lens made of plastic or silicone into the eye to replace the natural lens. The new lens is in accordance to last a lifetime.

Cataract surgery is generally safe and has a high success rate. Complications are rare.

Prevention of Cataract
