Abstract
PURPOSE: To determine the cataract surgical rate (CSR) between 2006 and 2010 in Iran. METHODS: In this cross-sectional study, sampling was done from surgical centers throughout Iran. Centers throughout all of Iran with more than 3000 surgeries per year were grouped as major centers and the rest were grouped as minor centers. All major centers and a percentage of minor centers were selected from each province. For each center, we determined the number of cataract surgeries in a random week of each season. RESULTS: Of the 237 eligible surgical centers, 124 were selected and 106 were enrolled in the study; 80 were major centers and 26 were minor centers. The number of surgeries has increased from 335,948 in 2006 to 475,526 in 2010. Cataract surgical rate has increased from 4723 (95% confidence interval, 4707 to 4739) per million population in 2006 to 6328 (95% confidence interval, 6309 to 6346) per million population in 2010. In the 50 and older population, CSR was 38,450 per million population in 2010. Average annual number of cataract surgeries per surgeon was 263 in 2006 and 339 in 2010. CONCLUSIONS: Compared with previous studies, the 2006 to 2010 CSR in Iran is on an ascending trend. Also, our numbers are higher than the minimum recommended by the World Health Organization, although lower than that in Western countries. Considering the aging population of the country, the observed rate is not sufficient for all cases of cataract in the future, and there is a need to increase CSR throughout the nation.
