About Half Needing Cataract Surgery Lack Access. How This Is Changing

A Lancet Global Health study finds only 48.2% of people worldwide who need cataract surgery can access it in 2025.

Coverage varies sharply by country, highlighting major gaps in global cataract care.

Because cataract surgery can prevent blindness, limited access leaves millions with avoidable vision loss.

Bloomberg Philanthropies’ Vision Initiative says it has helped more than 59,100 people reach surgery since launching in May 2025.
