Global prevalence of cataract surgery

The objective of this review article is to ascertain the global distribution of cataract surgery and evaluate the extent of its coverage in recent years.

The cataract surgical rate (CSR) has been reported from 36 to 12 800 (per million population) across different countries. The average cataract surgical coverage (CSC) in the majority of countries was around 50% or lower. Additionally, in many countries, the efficient CSC (eCSC) deviates from the CSC, emphasizing the importance of attention to the quality of surgical procedures. Socioeconomic status and access to health services are key determinants in the distribution of cataract surgery. This procedure is more prevalent among older individuals, with a higher incidence among men and private insurances tend to cover a larger portion of cataract surgeries. The pandemic of COVID-19 has had a detrimental effect on cataract surgery rates in numerous countries.

The rate of cataract surgery and its extent of coverage in certain countries is inadequate. The primary factor influencing the quantity and coverage of cataract surgeries is the economic status of the countries. Additionally, government support through insurance and the provision of appropriate healthcare services can contribute to an increase in cataract surgeries.
