Scope of the Problem
A recent study published in "The Lancet" indicates that nearly half of all people suffering from blindness due to cataracts have still not received the necessary surgical assistance.Worldwide, 94 million people are affected by cataracts, according to WHO. Medical professionals note that the surgery is not only simple but also effective, ensuring rapid vision recovery for many years.
As stated by Devorah Kestel, the Acting Director of the WHO Department of Noncommunicable Diseases and Mental Health, "Cataract surgery is one of the most effective ways to restore vision and improve people's quality of life."
"When people begin to see again, they also regain their independence, dignity, and opportunities," she added.
Positive Changes
According to WHO, over the past two decades, the number of cataract surgeries has increased by 15%, despite the growing demand due to an aging population and an increase in cases. It is projected that this figure will rise by another 8.4% in the current decade.It is noted that in different regions of the world, women are less likely to undergo this procedure compared to men.
Among the key reasons why people do not receive the necessary treatment are a lack of specialists, low income levels, and insufficient awareness.
Age is a major risk factor for developing cataracts, but they can also be caused by prolonged exposure to ultraviolet radiation, smoking, the use of corticosteroids, and diabetes.
Solutions to the Problem
WHO recommends that countries integrate vision screening into primary healthcare systems, invest in the development of surgical infrastructure, and ensure the availability of qualified specialists, especially in remote areas.Additionally, the organization emphasizes the need to eliminate gender and geographic inequalities. WHO hopes that cataract surgery will become accessible to all in the near future.
