Cataracts are one of the most common eye conditions affecting many people, especially as they age.

How the Eye Normally Works

In a healthy eye, there is a transparent lens that allows light to pass through, enabling the brain to process images of objects like houses, cows, and people.

Dr. Theophile Tuyisabe , the Director of Kabgayi Eye Unit, explains that this lens, which resembles a globe, is crucial for vision. It focuses light onto the retina, where information is sent to the brain.

What Happens with Cataracts

As people age, the lens of the eye can deteriorate much like how hair turns gray. This aging process causes the lens to become cloudy, impairing vision.

Dr. Tuyisabe likens this to looking through a broken or foggy glass. As the lens becomes cloudier, it reduces its ability to focus light properly, making everything appear hazy. If untreated, this can lead to complete blindness.

In Kinyarwanda, this condition is called ‘Ishaza’ or ‘Pea,’ reflecting the change in the lens’s appearance.

Who is at Risk?

While cataracts are primarily associated with aging, children can occasionally be born with them, and people can develop them at any age. However, the older you get, the more likely you are to develop cataracts.

Modern Solutions

The good news is that modern technology offers effective treatments for cataracts.

Dr. Tuyisabe shares inspiring stories of patients from various regions who, after treatment, can see clearly again. One common test involves asking patients to describe distant objects, which they can do accurately post-treatment.

Preventive Measures and Recommendations

Unfortunately, cataracts cannot be entirely prevented as they are a natural part of aging.

Dr. Tuyisabe advises that anyone experiencing symptoms like blurry or foggy vision should seek medical attention promptly to prevent blindness.
