“…[14] Through the RAAB Repository an increasing amount of comparable data are available from different settings,[30] including examples of national follow-up surveys that monitor change over time. [39] eCSC can be generated retrospectively from data previously collected, as demonstrated here. In future, it can be calculated easily from standard data collected in RAAB and other visual impairment surveys, and to ensure consistent and comparable results, the calculation of eCSC could be incorporated into the automated RAAB analysis.…”

Objective To define and demonstrate effective cataract surgical coverage (eCSC), a candidate UHC indicator that combines a coverage measure (cataract surgical coverage, CSC) with quality (post-operative visual outcome). Methods All Rapid Assessment of Avoidable Blindness (RAAB) surveys with datasets on the online RAAB Repository on April 1 2016 were downloaded. The most recent study from each country was included. By country, cataract surgical outcome (CSOGood, 6/18 or better; CSOPoor, worse than 6/60), CSC (operated cataract as a proportion of operable plus operated cataract) and eCSC (operated cataract and a good outcome as a proportion of operable plus operated cataract) were calculated. The association between CSC and CSO was assessed by linear regression. Gender inequality in CSC and eCSC was calculated. Findings Datasets from 20 countries were included (2005–2013; 67,337 participants; 5,474 cataract surgeries). Median CSC was 53.7% (inter-quartile range[IQR] 46.1–66.6%), CSOGood was 58.9% (IQR 53.7–67.6%) and CSOPoor was 17.7% (IQR 11.3–21.1%). Coverage and quality of cataract surgery were moderately associated—every 1% CSC increase was associated with a 0.46% CSOGood increase and 0.28% CSOPoor decrease. Median eCSC was 36.7% (IQR 30.2–50.6%), approximately one-third lower than the median CSC. Women tended to fare worse than men, and gender inequality was slightly higher for eCSC (4.6% IQR 0.5–7.1%) than for CSC (median 2.3% IQR -1.5–11.6%). Conclusion eCSC allows monitoring of quality in conjunction with coverage of cataract surgery. In the surveys analysed, on average 36.7% of people who could benefit from cataract surgery had undergone surgery and obtained a good visual outcome.

“…Moreover, cataract has been found to be the most common cause of blindness in various population-based studies. However, the cau- ses of blindness and its prevalence vary in countries depending on their levels of economic development and even within different regions of the same country (13,14,23,24) . A study on Latin American countries reported that unoperated cataract is the main cause of blindness (22) .…”

“…In the Barbados eye study, the most common causes of blindness were, in descending order, cataract (58.3%), glaucoma (14.3%), diabetic re tinopathy (8.7%), optic atrophy (7.1%), and AMD (2.4%) (23) . Cataract is also the main cause of blindness in Paraguay (24) . In several studies performed in European countries and the USA, which are places with high life expectancy, the most common cause of visual impairment has been shown to be AMD (25,26) .…”

Purpose: To identify the prevalence of ophthalmologic diseases in elderly patients who had been classified as severely disabled and to identify the ophthalmologic conditions leading to visual impairment and blindness. Methods: The medical records of 2806 patients who had applied to the Health Board of the Erzurum Region Training and Research Hospital between January 2011 and December 2012 were reviewed. One hundred ninety-nine patients aged >64 years who were classified as severely disabled with disability rates of over 50%, and who were unable to care for themselves or to move and/or communicate without help were included in the study. Results:The most frequently seen disabilities were neurological (47.2%) and those resulting from eye diseases (17.1%). The most common ophthalmologic diseases were cataract, glaucoma, and age-related macular degeneration. The mean right and left eye visual acuities were 1.17 ± 1.10 logMAR and 1.13 ± 1.0 logMAR, respectively. Of the 60 patients with ophthalmologic diseases or conditions, 33 were blind (visual acuity worse than 20/400) and 10 were visually impaired (visual acuity worse than 20/70 but better than 20/400). Cataracts were the main cause of blindness. The mean age of the patients who were still being followed up at the time of application to the disability board was significantly lower than that of the others (p=0.015). Seventy-nine percent of the blind patients were from rural areas, and 88% of these had no regular follow-up. Among the blind and visually impaired, significantly more patients from urban areas had social security insurance (SSI) than those from rural areas (p=0.043). Nearly 64% of the blind patients were women. The follow-up rate was significantly lower in women (p=0.025). According to multinomial logistic regression analysis, the visually impaired and blind patients were more likely to have lower follow-up rates than the other types of severely disabled patients (OR: 0.231, 95% Cl: 0.077-0.688, p=0.009). Conclusions: Blindness gives rise to severe disability, and the most common ophthalmologic diseases that cause severe disabilities in elderly patients are ca taract, glaucoma, and age-related macular degeneration. Sociodemographic factors that may affect the accessibility of visually impaired and blind people to health services include their place of residence and gender.

“…Still, the overall quality of cataract surgery in Suriname was relatively good when compared with other countries in the region. Only Argentina (82% good, 8.8% borderline and 9.2% poor outcomes) and Paraguay (77% good, 15.3% borderline and 7.7% poor outcomes) showed comparable results 1 12 27. The better national visual outcomes of eyes operated during the last 3 years when compared with those operated 4–6 years and 7 or more years ago could be anticipated, as surgeon skills, surgical facilities, and thus surgical outcome, continued to improve (expert opinion JP).…”
