“…8 In our previous study, we evaluated the changes of cataract surgical rate in each country in the last decade and revealed a close association between cataract surgical rate and country per capita gross domestic product. 9 Although it is also valuable for policy making and program planning, knowledge of the health burden of cataract was not adequate. The aim of this study was to evaluate the time trends of the global health burden of cataract vision loss and its distribution across age, sex, and national levels of socioeconomic development.…”

“…The economy may be implicated as one possible determinant of output and quality of cataract surgery. 9 The number of ophthalmologists per million people varied with socioeconomic development, with higher concentration in regions with higher HDI and per capita gross domestic product. [19][20][21] Globally, the preoperative visual acuity with regard to cataract surgery was associated with increasing HDI and per capita income.…”

PURPOSE.To evaluate the global trends in health burden of people visually impaired from cataract in terms of disability-adjusted life years (DALY) and its correlations with national levels of socioeconomic development.METHODS. Global, regional, and national DALY numbers, crude rate, and age-standardized rate of cataract vision loss by age and sex were obtained from the database of the Global Burden of Disease Study 2015. The human development index, per capita gross domestic product, and other country-level data were derived from international open databases. Regression analysis was used to assess the correlations between age-standardized DALY rate and socioeconomic variables. HDI,) for high HDI, and 17.10 (95%CI: 13.91-26.84) for very high HDI countries (P < 0.01), respectively. The national agestandardized DALY rates in 2015 were negatively associated with both HDI (R 2 ¼ 0.489, P < 0.001) and per capita gross domestic product (R 2 ¼ 0.331, P < 0.001). Stepwise multiple regression showed that HDI was significantly correlated with national age-standardized DALY rates in 2015 after adjusting for other confounding factors (P < 0.001). RESULTS. CONCLUSIONS.The global health burden of vision loss due to cataract increased between 1990 and 2015 despite considerable efforts from the World Health Organization and VISION 2020 initiatives.

Purpose The purpose of this study was to establish a standardized in vitro phacoemulsification damage model for future investigations of the effects of phacoemulsification, surgical devices, protective ophthalmic viscoelastic devices (OVDs), irrigation solutions and other aspects related to cataract phacoemulsification surgery on the corneal endothelium using porcine eyes. Methods Thirty‐four porcine eyes were randomly assigned to three groups (phacoemulsification (n = 13), irrigation (n = 9), control (n = 12)). A total of 5 min of ultrasound energy with intermittent irrigation/aspiration was applied in the eyes of the phacoemulsification group. The eyes of the irrigation group received the identical treatment, but without the application of ultrasound energy. The control group was left untreated. All eyes were then prepared to split corneal buttons followed by 15 days of cultivation. Endothelial cell density (ECD) was assessed blinded on day 15. Results Endothelial cell density declined significantly more until day 15 in the phacoemulsification group (2567 ± 317/267 cells/mm² (median ± 25%/75%‐quartiles), −32.5 ± 7.0/6.4%) compared to the irrigation (3450 ± 350/383 cells/mm², −11.8 ± 5.3/2.6%; p < 0.001) and the control group (3650 ± 288/258 cells/mm², −10.2 ± 3.2/4.6%; p < 0.001). Conclusion The phacoemulsification damage model presented in this study is sensitive to phacoemulsification energy and may reliably be used to investigate various factors involved in phacoemulsification with regard to their influence on corneal endothelial cells. This method is able to replace animal experiments or in vitro cell culture experiments that often do not translate well to the in vivo situation in humans.
