Scope of the Problem
A study published in the journal "Lancet" shows that about 50% of all people suffering from blindness caused by cataracts still need surgical intervention.According to WHO, there are 94 million patients with cataracts worldwide. Medical experts assert that the surgery to remove cataracts is effective and allows for long-term vision restoration.
As noted by Devorah Kestel, 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 change people's lives."
"When people regain their sight, they gain independence, dignity, and new opportunities," she added.
Positive Trends
According to WHO data, over the past two decades, the number of people undergoing this surgery has increased by 15%, despite the growing demand associated with the rising number of cataract cases due to an aging population. An additional 8.4% increase in surgeries is expected during the current decade.It is noted that in all regions, men are more likely to undergo the necessary procedure than women.
Among the reasons patients do not receive treatment are a shortage of doctors, low income levels, and insufficient awareness of the disease.
Age is a primary factor contributing to the development of cataracts, which can also occur due to prolonged exposure to UV radiation, smoking, corticosteroid use, and diabetes.
Recommendations to Address the Issue
WHO suggests 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.The organization also emphasizes the need to eliminate gender and geographic inequality. Cataract surgery could become accessible to everyone in the near future.
