Schuster AK, Nickels S, Pfeiffer N, et al. - Researchers conducted this population-based Gutenberg Health Study in Germany to determine the frequency of cataract surgery and to assess its effect on visual function in an adult population. The baseline examination of the study cohort was performed between 2007 and 2012 and the 5-year follow-up between 2012 and 2017. Using multivariable logistic regression analysis, association analyses were conducted to determine social and ocular associated factors. In total, 10,544 people aged 35 to 74 years were bilateral phakic at baseline and had information on lens status at the 5-year examination. At younger ages, the frequency of cataract surgery is low and increases up to 26% at age 70–74 years. Glaucoma sufferers are more likely to undergo cataract surgery at population-based level in Germany.
