Frequency and source of prescription eyewear insurance coverage in Ontario: a repeated population-based cross-sectional study using survey data.

BACKGROUND: Insurance coverage may reduce cost barriers to obtain vision correction. Our aim was to determine the frequency and source of prescription eyewear insurance to understand how Canadians finance optical correction. METHODS: We conducted a repeated population-based cross-sectional study using 2003, 2005 and 2013-2014 Canadian Community Health Survey data from respondents aged 12 years or older from Ontario, Canada. In this group, the cost of prescription eyewear is not covered by the government unless one is registered with a social assistance program or belongs to a specific population. We determined the frequency and source of insurance coverage for prescription eyewear in proportions. We used survey weights provided by Statistics Canada in all analyses to account for sample selection, a complex survey, and adjustments for seasonal effect, poststratification, nonresponse and calibration. We compared unadjusted proportions and adjusted prevalence ratios (PRs) of having insurance. RESULTS: Insurance covered all or part of the costs of prescription eyewear for 62% of Ontarians in all 3 survey years. Of those insured, 84.1%-86.0% had employer-sponsored coverage, 9.0%-10.3% had government-sponsored coverage, and 5.7%-6.8% had private plans. Employer-sponsored coverage remained constant for those in households with postsecondary graduation but decreased significantly for those in households with less than secondary school graduation, from 67.0% (95% confidence interval [CI] 63.2%-70.8%) (n = 175 000) in 2005 to 54.6% (95% CI 50.1%-59.2%) (n = 123 500) in 2013-2014. Government-sponsored coverage increased significantly for those in households with less than secondary school graduation, from 29.2% (95% CI 25.5%-32.9%) (n = 76 400) in 2005 to 41.7% (95% CI 37.2%-46.1%) (n = 93 900) in 2013-2014. In 2013-2014, Ontarians in households with less than secondary school graduation were less likely than those with secondary school graduation to report employer-sponsored coverage (adjusted PR 0.79, 95% CI 0.75-0.84) but were more likely to have government-sponsored coverage (adjusted PR 1.27, 95% CI 1.06-1.53). INTERPRETATION: Sixty-two percent of Ontarians had prescription eyewear insurance in 2003, 2005 and 2013-2014; the largest source of insurance was employers, primarily covering those with higher education levels, whereas government-sponsored insurance increased significantly among those with lower education levels. Further research is needed to elucidate barriers to obtaining prescription eyewear and the degree to which affordability impairs access to vision correction.

Achieving self-sustainability of service delivery in an eye care program in Madagascar using time-driven activity based costing.

BACKGROUND: In the absence of adequate and reliable external funding, eye care programs in developing countries need a high level of financial self-sustainability for maintenance and growth. To cope with these cost pressures, an eye care program in Sava, Madagascar adopted a Time-Driven Activity Based Costing (TDABC) methodology to better manage the cost of, and to improve revenue associated with, their three principle activities: consultation visits, cataract operations, and sale of glasses. METHODS: Direct (variable) and indirect (fixed) cost estimates and revenue sources were gathered by activity (consultation, cataract operation, sale of glasses) and location (hospital or outreach) and TDABC models were established. Estimates were made of the proportion of the ophthalmologist's time (by far the scarcest and most expensive resource) dedicated to consultation, cataract operation, or sale of glasses. These proportions were used to attribute costs by activity. The hospital manager and medical director modified staff roles, program activities, and infrastructure investments to reduce costs and expand revenue sources by activity while monitoring activity specific efficiency and profit. RESULTS: The TDABC model for patient consultations showed that they were time consuming for the ophthalmologist and only resulted in net profit for the institution if the ophthalmologist converted most cataract patients into accepting surgery and refractive error patients into purchasing glasses from the hospital optical shop. The TDABC model for cataract surgery showed the programs needed to reduce the cost of imported consumable surgical products, reduce operation time, and, most importantly, reduce the number of very costly surgical camps providing essentially free surgery. In addition the model pushed the hospital to train staff in marketing skills so that a higher proportion of cataract cases come directly to the hospital willing to pay for surgery. The TDABC model provided the optical shop manager, for the first time, data on both the cost of supplies (frames and lenses) and the price of glasses sold resulting in strategies to maximize profit through preferential product presentation and customer experience. The eye program in the Sava region in northern Madagascar improved its cost recovery from 68 to 102% through patient revenue. CONCLUSIONS: TDABC models helped the Sava eye care program develop more efficient service delivery and increase revenue in excess of steadily increasing costs.

Trends in Eye Care Use and Eyeglasses Affordability: The US National Health Interview Survey, 2008-2016.

Importance: Understanding eye care use over time is essential to estimate continued unmet health care needs and help guide future public health priorities. Objective: To update trends in using eye care and affording eyeglasses in the United States. Design, Setting, and Participants: This analysis of data from the US National Health Interview Survey included adults 18 years and older from 9 annual cross-sectional population-based samples ranging in size from 21 781 to 36 697 participants from 2008 to 2016. Data were analyzed from August 2017 to February 2018. Exposures: Visual impairment, defined as self-reported difficulty seeing despite wearing eyeglasses. Main Outcomes and Measures: Outcome measures included visits to an eye care professional and inability to afford eyeglasses when needed in the past year. Survey logistic regression, adjusted for age, sex, race/ethnicity, visual impairment status, education, employment, general health, poverty-income ratio, and vision insurance, was used to examine associations between survey year and eye care outcomes. Results: Analyses included 9 annual cross-sectional population-based samples pooled from 2008 to 2016, ranging in size from 21 781 to 36 697 participants aged 18 years or older. Compared with 2008, greater proportions of the US population were 65 years or older, Hispanic, or Asian in 2016. There was a significant trend for eye care use and difficulty affording eyeglasses from 2008 to 2016. In fully adjusted models, Americans were less likely to use eye care in 2014 compared with 2008 (odds ratio [OR], 0.90; 99.9% CI, 0.82-0.98; P < .001). Compared with 2008, Americans were also less likely to report difficulty affording eyeglasses from 2014 onwards (2014: OR, 0.82; 99.9% CI, 0.69-0.97; P < .001; 2015: OR, 0.81; 99.9% CI, 0.69-0.96; P < .001; 2016: OR, 0.70; 99.9% CI, 0.59-0.82; P < .001). After adjusting for all covariates, including survey year, those with visual impairment compared with those without were more likely to use eye care (OR, 1.54; 99.9% CI, 1.45-1.65; P < .001) but had greater difficulty affording eyeglasses (OR, 3.86; 99.9% CI, 0.58-0.72; P < .001). Women were also more likely to use eye care (OR, 1.42; 99.9% CI, 1.37-1.48; P < .001) and report difficulty affording eyeglasses (OR, 1.68; 99.9% CI, 1.56-1.81; P < .001) compared with men. Compared with non-Hispanic white individuals, black, Asian, and Hispanic individuals were less likely to use eye care, and Asian and black individuals were less likely to have difficulty affording eyeglasses. Conclusions and Relevance: These data indicate decreased difficulty affording eyeglasses among Americans from 2014 to 2016, possibly related to economic recovery and health care reform. However, the findings suggest women and racial/ethnic minorities are more likely to have lower use of eye care or inability to afford eyeglasses.

Potential Lost Productivity Resulting from the Global Burden of Myopia: Systematic Review, Meta-analysis, and Modeling.

PURPOSE: We estimated the potential global economic productivity loss resulting from vision impairment (VI) and blindness as a result of uncorrected myopia and myopic macular degeneration (MMD) in 2015. CLINICAL RELEVANCE: Understanding the economic burden of VI associated with myopia is critical to addressing myopia as an increasingly prevalent public health problem. METHODS: We estimated the number of people with myopia and MMD corresponding to critical visual acuity thresholds. Spectacle correction coverage was analyzed against country-level variables from the year of data collection; variation in spectacle correction was described best by a model based on a human development index, with adjustments for urbanization and age. Spectacle correction and myopia data were combined to estimate the number of people with each level of VI resulting from uncorrected myopia. We then applied disability weights, labor force participation rates, employment rates, and gross domestic product per capita to estimate the potential productivity lost among individuals with each level and type of VI resulting from myopia in 2015 in United States dollars (US$). An estimate of care-associated productivity loss also was included. RESULTS: People with myopia are less likely to have adequate optical correction if they are older and live in a rural area of a less developed country. The global potential productivity loss associated with the burden of VI in 2015 was estimated at US$244 billion (95% confidence interval [CI], US$49 billion-US$697 billion) from uncorrected myopia and US$6 billion (95% CI, US$2 billion-US$17 billion) from MMD. Our estimates suggest that the Southeast Asia, South Asia, and East Asia Global Burden of Disease regions bear the greatest potential burden as a proportion of their economic activity, whereas East Asia bears the greatest potential burden in absolute terms. CONCLUSIONS: Even under conservative assumptions, the potential productivity loss associated with VI and blindness resulting from uncorrected myopia is substantially greater than the cost of correcting myopia.

Comparison Of Health Insurance Coverage For Hearing Aids And Other Services In Alberta.

OBJECTIVES: Of the several barriers associated with uptake and adherence to hearing services, cost is the most commonly identified barrier in Canada. This study evaluated health insurance plans for hearing care coverage within Alberta, Canada, and subsequent out-of-pocket expenses that would result if an individual chose to pursue treatment. METHODS: An investigation of eight companies that provide supplementary health coverage in Alberta was conducted. Categories of health service coverage included hearing, vision, speech-language pathology (S-LP), physical therapy related (PT-R; including massage therapy and chiropractic therapy) and alternative medicine related (AM-R; including osteopathy, acupuncture and naturopathy). All coverage amounts were corrected to a four-year term for comparison purposes. RESULTS: For a four-year term, the coverage amounts for hearing services were CAD 300-750; for vision services were CAD 0-900; for S-LP services were CAD 0-2,400; for PT-R services were CAD 1,400-10,200; and for AM-R services were CAD 0-10,200 per four-year term. The expected out-of-pocket expense for vision ranged from CAD 0 to CAD 2,766, whereas for hearing, it ranged from CAD 250 to CAD 11,700. CONCLUSION: A considerable range and discrepancy were reported between hearing care and most paramedical services. In addition, the coverage amounts for hearing care were inconsistent with treatment costs, resulting in considerable out-of-pocket expenses for most consumers. The potential implications of such cost-related barriers on public health are an important consideration as our understanding of the impact of untreated hearing impairment continues to increase.

Spectacle prescriptions review to determine prevalence of ametropia and coverage of frequent replacement soft toric contact lenses.

PURPOSE: To determine the prevalence of ametropia and astigmatism in a clinic population and to estimate the coverage of frequent replacement soft toric lenses. METHODS: A review of patient files was conducted at three clinical sites. Prescription data collected between January 2014 and March 2017 in a patient cohort 14 to 70 years of age inclusive were analyzed to determine prevalence of ametropia and astigmatism. The percent coverage of frequent replacement soft toric contact lenses has further been estimated using different ranges for sphere, cylinder and axis availability. RESULTS: In total 101,973 patients were included in the analysis of which 69.5% were considered myopic, 26.9% hyperopic and 3.5% emmetropic as determined by the eye with the larger absolute value of the spherical equivalent refraction. Astigmatism in at least one eye was found in 87.2% of the population, with 37.0% of the patients exhibiting astigmatism of at least -1.00DC in at least one eye. With-the-rule astigmatism was most prevalent in the 14 to 20 year-olds (53.0%), while against-the-rule astigmatism was most prevalent in the 41 to 70 year-olds (50.7%). For astigmatic eyes with a cylinder of at least -0.75DC (n = 83,540; 41% of all eyes), the coverage with toric soft lenses varied greatly depending on parameter availability and ranged between 30.7% (sphere: Plano to -3.00D, cylinder: up to -1.75DC, axes: 90 ±â€¯10° and 180 ±â€¯10°) and 96.4% (sphere: + 6.00D to -10.00D, cylinders: up to -2.75DC, 18 axes). CONCLUSION: Currently available frequent replacement soft toric contact lenses provide coverage for up to 96.4% of potential patients.

Significant disparities in eyeglass insurance coverage in Canada.

OBJECTIVE: To describe patterns of access to eyeglass insurance by Canadians. DESIGN: A population-based, cross-sectional survey. PARTICIPANTS: A total of 134 072 respondents to the Canadian Community Health Survey 2003 who were aged ≥12 years. METHODS: We compared self-reported insurance coverage for eyeglasses or contact lenses provided by private, government, or employer-paid plans. RESULTS: Overall, 55.0% of Canadians aged ≥12 years had insurance that covers all or part of the costs of optical correction. School-age children (63.3%) and individuals aged 20-39 years (55.9%) and 40-64 years (59.5%) had higher coverage rates than seniors (aged ≥65 years) (33.8%, p < 0.05). Canadians residing in the 3 territories had the highest coverage (76.9%), while those in Quebec had the lowest coverage (39.1%, p < 0.05). Lower coverage was reported among immigrants (47.3%) versus nonimmigrants (57.4%, p < 0.05), nonwhites (49.2%) versus whites (56.4%, p < 0.05) and aboriginals (70.7%), and the self-employed (38.5%) versus employees (63.8%). Among Canadians in the 20-64 years age group, individuals in the lower or middle income bracket were 40% (prevalence ratio [PR] 0.60, p < 0.05) less likely to have insurance than those in the upper-middle or higher income bracket after adjusting for ethnicity, immigrant status, and education. Compared to those with university or college education, individuals with less than secondary school education were 13% (adjusted PR 0.87, p < 0.05) less likely to have insurance. CONCLUSIONS: Significant disparities exist in eyeglass insurance coverage in Canada. Individuals with low levels of income and education, and the self-employed, seniors, immigrants, nonwhites, and residents of Quebec had less coverage. Studies are needed to understand whether these disparities contribute to the visual impairment burden in Canada.

Pattern and Prevalence of Refractive Error and Secondary Visual Impairment in Patients Attending a Tertiary Hospital in Dhulikhel, Nepal.

Background Uncorrected refractive error is one of the most important causes of visual impairment worldwide. Objective To ascertain the pattern and prevalence of refractive error and secondary visual impairment in subjects attending Ophthalmology department. Method A prospective hospital-based study was designed where presenting visual acuity, age of presentation, refractive status, best corrected visual acuity and status of visual impairment were assessed in participants, ages ranging from 3-39 years presenting to the Ophthalmology department of Dhulikhel Hospital, Kathmandu University Hospital. History of use of spectacle was noted and participants were categorized into different visual impairment categories as per their presenting visual acuity. Result Out of a total of 4500 total clients examined during the study period, 388 (8.62%) had refractive error where 219 (56.44%) were females and 169 (43.56%) were males. Mean age at presentation was 22.70±7.69 years (range, 3-39 years). Astigmatism was the most common subtype seen in 373 eyes (48.06%), followed by myopia (366 eyes, 47.16%) and hypermetropia (31 eyes, 4.0%). Only 40.50% subjects who required refractive correction were using spectacle. 62.37% (242 clients) had some of visual impairment during their presentation. There was statistically significant improvement in visual acuity after refractive correction (p=0.00). Conclusion Uncorrected refractive error is one of the most important causes of visual impairment. Lack of awareness, infrequent ocular examination and lack of community or preschool vision screening were the main causes for the late presentation and significant visual impairment associated with the condition. Social stigma, economical limitation and negative counseling and attitudes about spectacle wear were primary factors behind the unsatisfactory spectacle use.

Cluster-randomized controlled trial of the effects of free glasses on purchase of children's glasses in China: The PRICE (Potentiating Rural Investment in Children's Eyecare) study.

BACKGROUND: Offering free glasses can be important to increase children's wear. We sought to assess whether "Upgrade glasses" could avoid reduced glasses sales when offering free glasses to children in China. METHODS: In this cluster-randomized, controlled trial, children with uncorrected visual acuity (VA)< = 6/12 in either eye correctable to >6/12 in both eyes at 138 randomly-selected primary schools in 9 counties in Guangdong and Yunnan provinces, China, were randomized by school to one of four groups: glasses prescription only (Control); Free Glasses; Free Glasses + offer of $15 Upgrade Glasses; Free Glasses + offer of $30 Upgrade Glasses. Spectacle purchase (main outcome) was assessed 6 months after randomization. RESULTS: Among 10,234 children screened, 882 (8.62%, mean age 10.6 years, 45.5% boys) were eligible and randomized: 257 (29.1%) at 37 schools to Control; 253 (28.7%) at 32 schools to Free Glasses; 187 (21.2%) at 31 schools to Free Glasses + $15 Upgrade; and 185 (21.0%) at 27 schools to Free Glasses +$30 Upgrade. Baseline ownership among these children needing glasses was 11.8% (104/882), and 867 (98.3%) children completed follow-up. Glasses purchase was significantly less likely when free glasses were given: Control: 59/250 = 23.6%; Free glasses: 32/252 = 12.7%, P = 0.010. Offering Upgrade Glasses eliminated this difference: Free + $15 Upgrade: 39/183 = 21.3%, multiple regression relative risk (RR) 0.90 (0.56-1.43), P = 0.65; Free + $30 Upgrade: 38/182 = 20.9%, RR 0.91 (0.59, 1.42), P = 0.69. CONCLUSIONS: Upgrade glasses can prevent reductions in glasses purchase when free spectacles are provided, providing important program income. TRIAL REGISTRATION: ClinicalTrials.gov Identifier: NCT02231606. Registered on 31 August 2014.

Assistive technology in resource-limited environments: a scoping review.

PURPOSE: It is estimated that only 5-15% of people in low and middle income countries (LMICs) who need assistive technologies (AT) have access to them. This scoping review was conducted to provide a comprehensive picture of the current evidence base on AT within LMICs and other resource limited environments. METHOD: The scoping review involved locating evidence, extracting data, and summarizing characteristics of all included research publications. RESULTS: Of the 252 publications included, over 80% focused on types of AT that address mobility (45.2%) and vision (35.5%) needs, with AT types of spectacles and prosthetics comprising over 50% of all publications. Evidence on AT that addresses hearing, communication, and cognition is the most underrepresented within the existing evidence base. The vast majority of study designs are observational (63%). CONCLUSIONS: Evidence on AT in resource-limited environments is limited in quantity and quality, and not evenly distributed across types of AT. To advance this field, we recommend using appropriate evidence review approaches that allow for heterogeneous study designs, and developing a common language by creating a typology of AT research focus areas. Funders and researchers must commit much greater resources to the AT field to ameliorate the paucity of evidence available. Implications for Rehabilitation An increase in the quality and quantity of research is required in resource limited environments, where 80% of the global population of people with disabilities reside. Improved and increased evidence is needed to identify and understand needs, inform policy and practice, and assess progress made in increasing access to and availability of appropriate AT. Over 80% of the existing research publications on assistive technologies in resource limited environments address mobility and vision. More research is needed on AT that address hearing, communication and cognition. The use of a common language would facilitate the advancement of the global AT research field. Specifically there is a need for researchers to use a common definition of AT (i.e., ISO 9999) and typology of AT research focus areas.

Visual health screening by schoolteachers in remote communities of Peru: implementation research.

OBJECTIVE: To describe the adaptation and scaling-up of an intervention to improve the visual health of children in the Apurimac region, Peru. METHODS: In a pilot screening programme in 2009-2010, 26 schoolteachers were trained to detect and refer visual acuity problems in schoolchildren in one district in Apurimac. To scale-up the intervention, lessons learnt from the pilot were used to design strategies for: (i) strengthening multisector partnerships; (ii) promoting the engagement and participation of teachers and (iii) increasing children's attendance at referral eye clinics. Implementation began in February 2015 in two out of eight provinces of Apurimac, including hard-to-reach communities. We made an observational study of the processes and outcomes of adapting and scaling-up the intervention. Qualitative and quantitative analyses were made of data collected from March 2015 to January 2016 from programme documents, routine reports and structured evaluation questionnaires completed by teachers. FINDINGS: Partnerships were expanded after sharing the results of the pilot phase. Training was completed by 355 teachers and directors in both provinces, belonging to 315 schools distributed in 24 districts. Teachers' appraisal of the training achieved high positive scores. Outreach eye clinics and subsidies for glasses were provided for poorer families. Data from six districts showed that attendance at the eye clinic increased from 66% (45/68 children referred) in the pilot phase to 92% (237/259) in the implementation phase. CONCLUSION: Adaptation to the local context allowed the scaling-up of an intervention to improve visual health in children and enhanced the equity of the programme.

Patient Perspectives on Acquiring Spectacles: A Cambodian Experience.

PURPOSE: To assess the perspectives of patients who acquired spectacles from an eye unit/vision center in Cambodia. DESIGN: A sample (n = 62) of patients was selected across 4 provinces: Prey Veng, Siem Reap, Battambang, and Takeo. METHODS: The Patient Spectacle Satisfaction Survey covering demographic and semistructured questions regarding patient satisfaction, style, and costs incurred was used to collect data. Information was transcribed and translated into English and analyzed by thematic coding using NVivo. RESULTS: Although there were more women seeking eye health care treatment, there was no significant age difference. Patient satisfaction levels were high although the patients had to pay for transportation, registration, and the glasses themselves. A total of 60 patients (96.7%) stated they would recommend the refractive service center to others. Despite a high level of awareness of eye disease such as cataract, only 2 in 10 people could accurately identify cataract as a major cause of poor vision or blindness. Most of the people (52%) blamed bad vision or blindness on dust or other foreign objects getting into the eye, old age (31%), or poor hygiene (16%). CONCLUSIONS: Most people will pay eye care costs once barriers to seeking treatment have been broken via education and encouragement. Satisfaction of wearing spectacles was associated with improved vision; style, color, and fit of the spectacles; and protection from sunlight and dust. The proximity of and easy access to health facilities influenced patient desire to seek treatment.

How Do Patients Choose Their Spectacles in the Public Sector of South Africa?

PURPOSE: This study was designed to understand the profiles of the patients who attended and chose to purchase spectacles from the public sector eye clinics in KwaZulu Natal, South Africa. Furthermore, we wished to explore patients' perceptions of the spectacle frames on offer and to understand the motivation of the patients in selecting their spectacle frames. METHODS: This descriptive study consented 674 patients from seven eye clinics in KwaZulu Natal. Each was interviewed using a questionnaire containing open-ended, close-ended questions and questions with a Likert-scale response. RESULTS: Females comprised 68.4% of the study population. The majority of participants had not completed secondary school or had no schooling (78.9%), were unemployed (70.9%), and earned less than R2000 per month or did not have any form of income (89.2%). Of the 670 who chose to buy spectacles from the eye clinics, 79.4% indicated that this was convenient (79.4%) and 23.0% said that they were motivated in their decision because they liked the available frames. More than 95% of participants rated the design, quality, and price as good to excellent. Factors influencing their decisions included design, recommendations from staff, and quality. Those who bought the spectacles from the budget range were prepared to pay more for the next pair of spectacles, whereas almost all reported that they would return to the same eye clinic for their next pair of spectacles and that they would recommend relatives and friends to the clinic. CONCLUSIONS: The results from the study indicate that there is high acceptance by patients of the range of spectacles offered in public sector eye clinics with specific suggestions to improve it. Increased understanding of the perceptions and motivations in spectacle choice will help inform planning and procurement decisions in supplying the needs of the patients and broadening the patient base.

Quality of sunglasses available in the Iranian market; a study with emphasis on sellers' license.

CONTEXT: Sunglasses should follow minimum requirements to sufficiently protect eyes. It is not known whether all items obtainable from the market are appropriately designed. AIMS: To compare ultraviolet (UV)-protective properties of commercially available sunglasses obtained from authorized and unauthorized Iranian sellers. Settings and Study Design: An analytic-descriptive study performed in a metropolitan area (Tehran). MATERIALS AND METHODS: Using a UV-visible standard spectrophotometer, the percentage transmittance was scanned between 280 and 400 nm in 348 pairs of nonprescription sunglasses (price range: 20-80 US$) obtained anonymously and randomly from authorized (permitted by the Ministry of Health, 189 pairs) and unauthorized (159 pairs) sellers in the Iranian capital city, Tehran. The Australian/New Zealand Standard (AS/NZS) and the American National Standards Institute [ANSI] standards were followed. STATISTICAL ANALYSIS: Chi-square test, independent samples t-test or Mann-Whitney U-test. Results UV-protective properties of the sunglasses obtained from authorized sellers complied with AS/NZS and ANSI guidelines in 92.6% and 95.2% of items, respectively. The corresponding rates for sunglasses obtained from unauthorized sellers were 0% and 8.2%, respectively (P < 0.001 for both). The rate of defective polarizing capability of lenses was 27.4% in sunglasses obtained from authorized sellers versus 90.4% in sunglasses obtained from unauthorized sellers (P < 0.001). Neither brand nor price played significant contributions to UV protection/lens polarizing capability of sunglasses obtained from authorized sellers. CONCLUSIONS: Sunglasses provided by unauthorized sellers are alarmingly unreliable and could be potentially hazardous for the eye. Brand and price do not guarantee optimal protection against UV radiation or polarizing performance of the lens.

Barriers to use of refractive services in Mozambique.

PURPOSE: Uncorrected refractive error remains a leading cause of visual impairment (VI) across the globe with Mozambique being no exception. The establishment of an optometry profession in Mozambique that is integrated into the public health system denotes significant progress with refractive services becoming available to the population. As the foundations of a comprehensive refractive service have now been established, this article seeks to understand what barriers may limit their uptake by the general population and inform decision making on improved service delivery. METHODS: A community-based cross-sectional study using two-stage cluster sampling was conducted. Participants with VI were asked to identify barriers that were reflective of their experiences and perceptions of accessing refractive services. A total of 4601 participants were enumerated from 76 clusters in Nampula, Mozambique. RESULTS: A total of 1087 visually impaired participants were identified (884 with near and 203 with distance impairment). Cost was the most frequently cited barrier, identified by more than one in every two participants (53%). Other barriers identified included lack of felt need (20%), distance to travel (15%), and lack of awareness (13%). In general, no significant influence of sex or type of VI on barrier selection was found. Location had a significant impact on the selection of several barriers. Pearson χ analysis indicated that participants from rural areas were found to feel disadvantaged regarding the distance to services (p ≤ 0.001) and adequacy of hospital services (p = 0.001). CONCLUSIONS: For a comprehensive public sector refractive service to be successful in Mozambique, those planning its implementation must consider cost and affordability. A clear strategy for overcoming lack of felt need will also be needed, possibly in the form of improved advocacy and health promotion. The delivery of refractive services in more remote rural areas merits careful and comprehensive consideration.

Costs of eye care services: prospective study from a faith-based hospital in Zambia.

PURPOSE: To estimate the mean costs of cataract surgery and refractive error correction at a faith-based eye hospital in Zambia. METHODS: Out-of-pocket expenses for user fees, drugs and transport were collected from 90 patient interviews; 47 received cataract surgery and 43 refractive error correction. Overhead and diagnosis-specific costs were determined from micro-costing of the hospital. Costs per patient were calculated as the sum of out-of-pocket expenses and hospital costs, excluding user fees to avoid double counting. RESULTS: From the perspective of the hospital, overhead costs amounted to US$31 per consultation and diagnosis-specific costs were US$57 for cataract surgery and US$36 for refractive error correction. When including out-of-pocket expenses, mean total costs amounted to US$128 (95% confidence interval [CI] US$96--168) per cataract surgery and US$86 (95% CI US$67--118) per refractive error correction. Costs of providing services corresponded well with the user fee levels established by the hospital. CONCLUSION: This is the first paper to report on the costs of eye care services in an African setting. The methods used could be replicated in other countries and for other types of visual impairments. These estimates are crucial for determining resources needed to meet global goals for elimination of avoidable blindness.
