Background Among the global population,cataract blindness continues to account for a major proportion of visual impairment in adults aged 50 years and older(1,2).In developing nations,there are still significant barriers that lead to inequities in the reversal of cataracts,and these include lack of government funding,issues surrounding costs,and insufficient number of ophthalmologists(3).In China,cataract blindness continues to be a leading public-health issue due to its ageing population(4).It has been previously suggested that China has one of the lowest cataract surgery rates with Asia,with 1,067 cases performed per million population in 2014(5).
