Comparison of cataract surgery outcomes between a secondary and a tertiary eye hospital in Tamil Nadu, India. Eye (Lond) 2024; 38:335-342. [PMID: 37553356 PMCID: PMC10811324 DOI: 10.1038/s41433-023-02687-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/14/2022] [Revised: 07/26/2023] [Accepted: 07/27/2023] [Indexed: 08/10/2023] Open
Abstract
PURPOSE To examine the difference in post-operative visual outcomes of cataract surgeries between a tertiary and secondary centre at Aravind Eye Hospitals in Tamil Nadu, India. METHODS Our retrospective cross-sectional study analysed cataract surgeries at a secondary centre and its associated tertiary centre in 2021. Our main outcome measures were postoperative best corrected visual acuity (BCVA), spherical equivalent, and intraoperative and postoperative complications. Two-sample proportion tests and logistic regression analyses were performed. RESULTS The analysis of 32,302 cataract surgeries in 2021 of which 4357 were performed at the secondary centre and 27,945 were performed at the tertiary centre showed that the tertiary centre operated on more advanced cataract condition (p < 0.001). Intraoperative (p < 0.001) and post-operative complication rates (p < 0.001) were higher in the tertiary centre. The odds of effective outcomes (BCVA > = 6/12) controlling for all covariates are poorer (p < 0.0001) in the tertiary centre for both phacoemulsification (phaco) and manual small incision cataract surgeries (MSICS). CONCLUSION World Health Organization recommendations for the effective outcome of cataract surgery are met by both the tertiary and secondary centres, but the odds of effective outcomes in the tertiary centre was lower after adjusting for all known factors. Further investigations of the causes of poor vision in both phaco and MSICS in the tertiary centre are needed to improve the situation.

Abstract
OBJECTIVE The aim of the current study was to explore the spatial and temporal distribution characteristics of registered cases of cataract surgery in China from 2013 to 2017. METHODS A database for spatial analysis of cataract surgery in China in 2013-2017 was established using ArcGIS10.0 software as a platform for data management and presentation. Spatial autocorrelation analysis of cataract surgery was undertaken, and temporal and spatial scan analysis was done using SaTScan 9.5 software. RESULTS From 2013 to 2017, annual cataract surgery rates (CSRs) in China were 1200, 1400, 1782, 2070, and 2205 per 1 million population, indicating a gradually increasing trend. Local Moran's I autocorrelation analysis showed that there was spatial clustering of CSR in China, with Anhui being a low-high clustering region. Findings of global hotspot analysis Getis-Ord General G showed that General G index of national CSR was <0.01, Z = 1.12, P = 0.26. Findings of staged spatial-temporal scan analysis indicated that 18 areas of aggregation were found in 2 stages. Observed differences in each clustering area were statistically significant (P < 0.05). CONCLUSION CSRs in China showed increasing trend year by year and were randomly distributed, with spatial clustering, and Anhui was reported as a low-high clustering region. However, high-risk areas still persist, requiring focused attention and targeted prevention and control measures.

[PMID: 32913291 PMCID: PMC8225659 DOI: 10.1038/s41433-020-0954-5] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/21/2019] [Revised: 04/27/2020] [Accepted: 04/30/2020] [Indexed: 11/08/2022] Open
Abstract
PURPOSE To report trends in cataract surgery indications, visual acuity outcomes, complication rates and reoperation rates at ten Aravind Eye Hospitals in Tamil Nadu, India. METHODS In this retrospective database study we analyzed seven years of data of cataract surgeries at Aravind during January 1, 2012 to December 31, 2018. Our main outcome measures were preoperative and 1-month postoperative uncorrected visual acuity (UCVA) and best-corrected visual acuity (BCVA); and rates of intraoperative complications and reoperations. We performed Cochran-Armitage trend tests. RESULTS In 1.86 million eyes that underwent cataract surgery, the percentage of eyes undergoing phacoemulsification (PE) showed an increasing trend (p < 0.0001), from 26.8% in 2012 to 33.5% in 2018. The percentage of eyes undergoing manual small incision cataract surgery (SICS) showed a decreasing trend (p < 0.0001), from 70.0% in 2012 to 65.1% in 2018. For SICS, the percentages of eyes with good postoperative UCVA and BCVA showed increasing trends (p < 0.0001 for each), and the percentages of eyes with poor postoperative UCVA and BCVA showed decreasing trends (p < 0.0001 for each). Results for PE surgeries were mixed. For both PE and SICS rates of intraoperative complications showed a declining trend (p < 0.0001 for each) and a slight increasing trend for reoperations (PE p < 0.02; SICS p < 0.0001). CONCLUSIONS During this seven-year period there were noticeable trends in cataract surgeries performed at Aravind in terms of the mix of surgical procedures, preoperative vision, and cataract surgical outcomes.

Abstract
PURPOSE To identify patient characteristics associated with follow-up compliance and to draw implications for better cataract treatment services. SETTING Aravind Eye Hospital, Madurai, India. DESIGN Retrospective case study. METHODS The data of all cataract surgeries performed in 2015 were analyzed. After each surgery, patients were asked to return for follow-up after 1 month. The follow-up rates were compared between patients with different demographic characteristics, surgical factors, and preoperative and discharge visual acuities. The behaviors of patients who complied with the follow-up advice were analyzed, including the number of days from surgery to follow-up and number of follow-up visits. Multivariate regression models were used to identify predictors associated with these behaviors. RESULTS The overall follow-up rate for the 86 776 surgeries analyzed was 85.6%. Patients more likely to follow-up were women, younger than 70 years, and paying (versus subsidized or free) and had phacoemulsification rather than manual small-incision cataract surgery (all P < .001). Patients who had complications, reoperations, or poorer visual acuity at discharge were less likely to comply with the follow-up advice (P < .001). CONCLUSIONS Targeted interventions to boost follow-up rates should be directed to patients with the characteristics found in this study. Furthermore, average measures of visual outcomes at 4 weeks are likely to be overstated relative to the truth.

Abstract
Background Visual impairment in developing countries has both social and economic impact on individuals and communities. Understanding the subjective visual functioning of populations will allow for local policymakers to identify the need for optometric or ophthalmic services in their communities. Methods The authors surveyed 644 adult patients in Mwanza, Tanzania at three clinics (Buzuruga, Mwananchi and Kisesa) using a modified Visual Functioning Questionnaire 25. Responses were categorized into General health, General vision, Ocular pain, Near activities, Distance activities, Social function, Mental health, Role difficulties, Color vision, Peripheral vision and Dependency. Results Patients at Buzuruga reported the lowest scores on most subscales. Of 100 employed patients, 37% claimed to have at least some difficulty in performing job duties due to their eyesight. At Kisesa, 146 (246/221) patients (66.1%) had never had an eye exam, compared with 134/227 (59.0%) at Buzuruga and 69/173 (39.9%) at Mwananchi (p<0.01). Common reasons for not seeing an eye doctor were the perceived expense and lack of vision problems. Conclusions Due to regional differences in visual functioning in Mwanza, a national effort for vision health cannot be entirely successful without addressing the individualized needs of local communities. Reducing the cost of vision care appointments may expand vision health care utilization in Mwanza.

Interventions to improve access to cataract surgical services and their impact on equity in low- and middle-income countries. Cochrane Database Syst Rev 2017; 11:CD011307.

Abstract
BACKGROUND Cataract is the leading cause of blindness in low- and middle-income countries (LMICs), and the prevalence is inequitably distributed between and within countries. Interventions have been undertaken to improve cataract surgical services, however, the effectiveness of these interventions on promoting equity is not known. OBJECTIVES To assess the effects on equity of interventions to improve access to cataract services for populations with cataract blindness (and visual impairment) in LMICs. SEARCH METHODS We searched the Cochrane Central Register of Controlled Trials (CENTRAL) (which contains the Cochrane Eyes and Vision Trials Register) (2017, Issue 3), MEDLINE Ovid (1946 to 12 April 2017), Embase Ovid (1980 to 12 April 2017), LILACS (Latin American and Caribbean Health Sciences Literature Database) (1982 to 12 April 2017), the ISRCTN registry (www.isrctn.com/editAdvancedSearch); searched 12 April 2017, ClinicalTrials.gov (www.clinicaltrials.gov); searched 12 April 2017 and the World Health Organization (WHO) International Clinical Trials Registry Platform (ICTRP) (www.who.int/ictrp/search/en); searched 12 April 2017. We did not use any date or language restrictions in the electronic searches for trials. SELECTION CRITERIA We included studies that reported on strategies to improve access to cataract services in LMICs using the following study designs: randomised and quasi-randomised controlled trials (RCTs), controlled before-and-after studies, and interrupted time series studies. Included studies were conducted in LMICs, and were targeted at disadvantaged populations, or disaggregated outcome data by 'PROGRESS-Plus' factors (Place of residence; Race/ethnicity/ culture/ language; Occupation; Gender/sex; Religion; Education; Socio-economic status; Social capital/networks. The 'Plus' component includes disability, sexual orientation and age). DATA COLLECTION AND ANALYSIS Two authors (JR and JP) independently selected studies, extracted data and assessed them for risk of bias. Meta-analysis was not possible, so included studies were synthesised in table and text. MAIN RESULTS From a total of 2865 studies identified in the search, two met our eligibility criteria, both of which were cluster-RCTs conducted in rural China. The way in which the trials were conducted means that the risk of bias is unclear. In both studies, villages were randomised to be either an intervention or control group. Adults identified with vision-impairing cataract, following village-based vision and eye health assessment, either received an intervention to increase uptake of cataract surgery (if their village was an intervention group), or to receive 'standard care' (if their village was a control group).One study (n = 434), randomly allocated 26 villages or townships to the intervention, which involved watching an informational video and receiving counselling about cataract and cataract surgery, while the control group were advised that they had decreased vision due to cataract and it could be treated, without being shown the video or receiving counselling. There was low-certainty evidence that providing information and counselling had no effect on uptake of referral to the hospital (OR 1.03, 95% CI 0.63 to 1.67, 1 RCT, 434 participants) and little or no effect on the uptake of surgery (OR 1.11, 95% CI 0.67 to 1.84, 1 RCT, 434 participants). We assessed the level of evidence to be of low-certainty for both outcomes, due to indirectness of evidence and imprecision of results.The other study (n = 355, 24 towns randomised) included three intervention arms: free surgery; free surgery plus reimbursement of transport costs; and free surgery plus free transport to and from the hospital. These were compared to the control group, which was reminded to use the "low-cost" (˜USD 38) surgical service. There was low-certainty evidence that surgical fee waiver with/without transport provision or reimbursement increased uptake of surgery (RR 1.94, 95% CI 1.14 to 3.31, 1 RCT, 355 participants). We assessed the level of evidence to be of low-certainty due to indirectness of evidence and imprecision of results.Neither of the studies reported our primary outcome of change in prevalence of cataract blindness, or other outcomes such as cataract surgical coverage, surgical outcome, or adverse effects. Neither study disaggregated outcomes by social subgroups to enable further assessment of equity effects. We sought data from both studies and obtained data from one; the information video and counselling intervention did not have a differential effect across the PROGRESS-Plus categories with available data (place of residence, gender, education level, socioeconomic status and social capital). AUTHORS' CONCLUSIONS Current evidence on the effect on equity of interventions to improve access to cataract services in LMICs is limited. We identified only two studies, both conducted in rural China. Assessment of equity effects will be improved if future studies disaggregate outcomes by relevant social subgroups. To assist with assessing generalisability of findings to other settings, robust data on contextual factors are also needed.

Judson K, Courtright P, Ravilla T, Khanna R, Bassett K. Impact of systematic capacity building on cataract surgical service development in 25 hospitals. BMC Ophthalmol 2017; 17:96. [PMID: 28629328 PMCID: PMC5477129 DOI: 10.1186/s12886-017-0492-5] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/12/2017] [Accepted: 06/08/2017] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND This study measured the effectiveness and cost of a capacity building intervention in 25 eye hospitals in South Asia, East Africa and Latin America over 4 years. The intervention involved eye care non-governmental organizations or high-performing eye hospitals acting as "mentors" to underperforming eye hospitals- "mentees" in 10 countries. Intervention activities included systematic planning and support for training and key equipment purchases as well as hospital-specific mentoring which focused on strengthening leadership, increasing the volume and equity of community outreach, improving surgical quality and volume, strengthening organizational and financial management and streamlining operational processes. METHODS This is a before and after observational study of the impact of this multi-dimensional process on hospital and individual productivity and financial sustainability after 4 years. Mentee hospitals reported data monthly using a standardized template. Key indicators included cataract surgery volume, cataract operations per surgeon, the proportion of direct paying cataract surgical patients, intervention program costs per additional surgery and cost per mentor. RESULTS By the end of the study period, the hospitals experienced a 69% average increase (range: -63% to 690%) in cataract surgical volume over baseline with 12 hospitals showing increases over 100%. Twenty-three hospitals experienced a 59% average increase in the number of cataract surgeries per surgeon with 10 hospitals showing increases over 100%. The proportion of paying patients increased in 8 of the 14 hospitals reporting this data. The average mentoring cost per additional surgery for these 25 hospitals was $5.39. An average of $36,489.99 was spent per mentor per year to support their work with mentees. CONCLUSIONS The intervention resulted in proportionally similar increases in cataract surgical volume and productivity across diverse settings in three distinct geographic regions. Its wide applicability and moderate cost make it an attractive means to rapidly and substantially increase eye care services to meet VISION2020 goals.

Abstract
Globally, pockets of 'neglected populations' do not have access to basic health-care services and carry a much greater risk of blindness and visual impairment. While large-scale public health approaches to control blindness due to vitamin A deficiency, onchocerciasis, and trachoma are successful, other causes of blindness still take a heavy toll in the population. High-quality comprehensive eye care that is equitable is the approach that needs wide-scale application to alleviate this inequity. L V Prasad Eye Institute of India developed a multi-tier pyramidal model of eye care delivery that encompasses all levels from primary to advanced tertiary (quaternary). This has demonstrated the feasibility of 'Universal Eye Health Coverage' covering promotive, preventive, corrective, and rehabilitative aspects of eye care. Using human resources with competency-based training, effective and cost-effective care could be provided to many disadvantaged people.

Abstract
Global blindness exacts an enormous financial and social cost on developing countries. Reducing the prevalence of blindness globally requires a set of strategies that are different from those typically used in developed countries. This was the subject of the 2013 Knapp symposium at the American Ophthalmological Society Annual Meeting, and this article summarizes the presentations of epidemiologists, health care planners, and ophthalmologists. It explores a range of successful strategies from the multinational Vision 2020 Initiative to disease-specific schemes in cataract, trachoma control, infectious corneal ulceration, cytomegalovirus retinitis, and retinopathy of prematurity. In each example, the importance of an attitudinal change set toward public health becomes clear. There is reason for optimism in the struggle against global blindness in large measure because of innovative programs such as those described here.

Evidence for integrating eye health into primary health care in Africa: a health systems strengthening approach. BMC Health Serv Res 2013; 13:102. [PMID: 23506686 PMCID: PMC3616885 DOI: 10.1186/1472-6963-13-102] [Citation(s) in RCA: 49] [Impact Index Per Article: 4.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/17/2012] [Accepted: 03/02/2013] [Indexed: 12/03/2022] Open
Abstract
Background The impact of unmet eye care needs in sub-Saharan Africa is compounded by barriers to accessing eye care, limited engagement with communities, a shortage of appropriately skilled health personnel, and inadequate support from health systems. The renewed focus on primary health care has led to support for greater integration of eye health into national health systems. The aim of this paper is to demonstrate available evidence of integration of eye health into primary health care in sub-Saharan Africa from a health systems strengthening perspective. Methods A scoping review method was used to gather and assess information from published literature, reviews, WHO policy documents and examples of eye and health care interventions in sub-Saharan Africa. Findings were compiled using a health systems strengthening framework. Results Limited information is available about eye health from a health systems strengthening approach. Particular components of the health systems framework lacking evidence are service delivery, equipment and supplies, financing, leadership and governance. There is some information to support interventions to strengthen human resources at all levels, partnerships and community participation; but little evidence showing their successful application to improve quality of care and access to comprehensive eye health services at the primary health level, and referral to other levels for specialist eye care. Conclusion Evidence of integration of eye health into primary health care is currently weak, particularly when applying a health systems framework. A realignment of eye health in the primary health care agenda will require context specific planning and a holistic approach, with careful attention to each of the health system components and to the public health system as a whole. Documentation and evaluation of existing projects are required, as are pilot projects of systematic approaches to interventions and application of best practices. Multi-national research may provide guidance about how to scale up eye health interventions that are integrated into primary health systems.

Abstract
There are over 300 million people living in the world today who are visually impaired and a further 45 million who are blind. The large majority (90%) of these people live in developing countries, and up to 75% of blindness are avoidable. With cataracts being the major cause of blindness and visual impairment, many ophthalmic aid programmes are aimed at alleviating the enormous burden caused by this readily treatable disease. Having said that, caution should be exercised that short surgical visits to remote rural areas that are not coordinated with local national eye care managers should be discouraged because they do little for the development of sustainable eye care programmes. With this in view, it has become imperative to design blindness prevention and ophthalmic support programmes that are workable, comprehensive, economical and sustainable.

Abstract
PURPOSE To examine the financial viability of the Timor-Leste National Spectacle Program as it increases spectacle availability, affordability and uptake, particularly for Timor's poor. METHODS In rural areas, three models of ready-made spectacles were dispensed according to a tiered pricing structure of US$3.00, 1.00, 0.10 and 0.00. In addition, custom-made spectacles were available in the capital, Dili. Spectacle costs, dispensing data and income for the National Spectacle Program for 18 months from March 2007 were analyzed. RESULTS Rural services dispensed 3415 readymade spectacles: 47.1% to women, and 51.4% at subsidized prices, being 39.8% at US$0.10 and 11.6% free. A profit of US$1,529 was generated, mainly from the sale of US$3.00 spectacles. Women (odds ratio, OR, 1.3, 95% confidence interval, CI, 1.1-1.4) and consumers aged ≥65 years (OR 2.1; 95% CI 1.7-2.6) were more likely to receive subsidized spectacles. Urban services dispensed 2768 spectacles; mostly US$3.00 readymade (52.8%) and custom-made single vision (29.6%) units. Custom-made spectacles accounted for 36.7% of dispensing, but 73.1% of the US$12,264 urban profit. The combined rural and urban profit covered all rural costs, leaving US$2,200 to meet administration and other urban expenses. CONCLUSION It is instructive and encouraging that a national spectacle dispensing program in one of the ten poorest countries of the world can use tiered-pricing based on willingness-to-pay information to cover spectacle stock replacement costs and produce profit, while using cross-subsidization to provide spectacles to the poor.

Abstract
Background: Globally, and in Africa, after adjusting for age, women are about 1.4 times more likely to be blind than men. While women generally live longer than men, the lack of accessibility to and use of services is likely the most important reason for excess blindness in women in Africa. Aim: We sought to review the literature on vision loss in Africa and summarize the findings related to gender equity. Materials and Methods: Information from across sub-Saharan Africa was collected on the evidence of gender inequity and reasons for this inequity. Finally, the results were used to generate suggestions on how gender equity could be improved. Results: In all published surveys (except one), cataract surgical coverage among women was lower than cataract surgical coverage among men. Although data available are limited, similar findings appeared in the use of services for other disease conditions, notably, childhood cataract and glaucoma. Evidence suggests that a variety of approaches are needed to improve the use of eye care services. Three main strategies are needed to address gender inequity in vision loss in Africa. First, it is important to address transport needs. Second, counseling of patients and family members is required. Finally, programs need to put in place pricing systems that make the services affordable the population. Conclusions: VISION 2020 can be achieved in Africa, but investment is needed in a variety of strategies that will ensure that eye care services are affordable, accessible, and acceptable to women and girls.

Abstract
The global initiative, "VISION 2020 - The Right to Sight" aims to eliminate avoidable blindness by year 2020. Avoidable blindness by definition are those conditions for which we already have a treatment or a surgical procedure and often a proven strategy to either prevent or cure the condition. Thus, the challenge to realize this goal would be designing the right service delivery systems specific to the local context, organizing the required resources, coordination, and implementing and monitoring these. The key "discipline" that is required to ensure successful implementation is "Management." To be holistic, such management inputs are required both in a program as well as the hospital setting. From a program perspective, the focus will need to be on reaching the unreached, ensuring equity, creating an enabling environment, putting in place the required infrastructure, including that for developing all cadres of the eye care team, and functionally integrating eye care into the general health system and other developmental activities. From a hospital perspective, the management process should manage the internal and external ecosystems as well as all the interfaces to the hospital. It should also put in place systems for ensuring an adequate patient flow, high productivity, quality, sustainability, and accountability. Since in many countries the notion of management in health care or more specifically in eye care is at an early stage or nonexistent, a proactive effort is required to build the management capacity quickly through a structured process.
