PURPOSE.To estimate prevalence and number of people visually impaired or blind due to cataract. METHODS.Based on the Global Burden of Diseases Study 2010 and ongoing literature research, we examined how many people were affected by moderate to severe vision impairment (MSVI; presenting visual acuity <6/18, ‡3/60) and blindness (presenting visual acuity <3/60) due to cataract. RESULTS.In 2010, of overall 32.4 million blind and 191 million vision impaired, 10.8 million people were blind and 35.1 million were visually impaired due to cataract. Cataract caused worldwide 33.4% of all blindness in 2010, and 18.4% of all MSVI. These figures were lower in the high-income regions (<15%) and higher (>40%) in South and Southeast Asia and Oceania. From 1990 to 2010, the number of blind or visually impaired due to cataract decreased by 11.4% and by 20.2%, respectively; the age-standardized global prevalence of cataract-related blindness and MSVI reduced by 46% and 50%, respectively, and the worldwide crude prevalence of cataract-related blindness and MSVI reduced by 32% and 39%, respectively. The percentage of global blindness and MSVI caused by cataract decreased from 38.6% to 33.4%, and from 25.6% to 18.4%, respectively. This decrease took place in almost all world regions, except East Sub-Saharan Africa.CONCLUSIONS. In 2010, one in three blind people was blind due to cataract, and one of six visually impaired people was visually impaired due to cataract. Despite major improvements in terms of reduction of prevalence, cataract remains a major public health problem.Keywords: cataract, epidemiology, blindness, visual impairment A lthough cataract is relatively easily, safely, and costefficiently treatable, and in spite of the increasing rates of cataract surgery, 1 cataract is still the leading cause of blindness and visual impairment worldwide, especially in developing countries. 2,3 Population-based studies and previous meta-analyses performed in different regions worldwide have reported that cataract is responsible for 47.8% to 51% of all global blindness. 2,4-9 However, these studies did not report data on the change during the past 2 decades in terms of prevalence and number of people blind or visually impaired due to cataract.The purpose of the current study was to determine, in a meta-analysis of all available population-based studies performed worldwide within the past 2 decades, prevalence and number of people affected by blindness and visual impairment due to cataract, to assess changes during the period from 1990 to 2010, and to examine regional differences in the prevalence of cataract-related blindness and visual impairment.

“…[1][2][3][4][5][6] In the hands of a capable surgeon, cataract surgery can result in good vision [7][8][9] and patient satisfaction 10 at least 90% of the time, and recent studies have shown that these operations can transform the economic outlook of patients and families. [10][11][12][13] It is thus particularly disturbing that patients with visually significant cataract refuse free or low-cost surgery in some 80% of cases, as documented in papers by Kovai and co-workers 14 and Zhang and co-workers 15 in the current issue.…”

“…14,15 Another paper in the current issue by Li and colleagues 16 reporting population-based cataract surgical outcomes in China suggests fear over bad results may be justified: only a third of patients had postoperative visual acuity 46/ 18, and nearly a third had56/60. Despite some trends towards improvement with wide adoption of intraocular lens surgery, larger population-based studies in China 17 and those from elsewhere in Asia 18,19 report similar results.…”

“…Also interesting is the fact that, although 510% of participants in the studies by Kovai and Zhang identified financial barriers as important in refusing surgery, having a low income was in fact an important risk factor for refusal in India. 14,15 In another article in the current issue, Schulze Schwering and co-authors 20 highlight that economic barriers remain important in the uptake of pediatric cataract surgery in Malawi. Though uptake was generally high (460%), other reports have shown that delays in surgery and poor follow-up, also potentially caused by economic barriers, can prevent good outcomes even where surgery is done well.…”

“…Though uptake was generally high (460%), other reports have shown that delays in surgery and poor follow-up, also potentially caused by economic barriers, can prevent good outcomes even where surgery is done well. 21 All the barriers reported in this issue [14][15][16]20 have been well-studied, and inarguably play a role in persistently low surgical rates. However, it would seem that the time for studying barriers to cataract surgery is past, and that our attention should now be turned to improving surgical quality, and testing interventions to improve uptake.…”

IMPORTANCE Cataract-related vision impairment is an important public health issue that tends to affect older adults. Little is known about the association between older adults' social support networks and their likelihood of receiving cataract surgery. OBJECTIVE To determine if older adults with smaller social support networks are less likely to receive cataract surgery. DESIGN, SETTING, AND PARTICIPANTS Retrospective cohort study. The National Health and Aging Trends Study, a nationally representative US survey, administered annually from 2011 to 2015 to a cohort of Medicare beneficiaries 65 years and older with no cataract surgery prior to the start of the study. MAIN OUTCOMES AND MEASURES Multivariable logistic regression was performed to evaluate if the number of persons in an individual's social support network influenced whether that individual received cataract surgery during a given year of the study.
