ABSTRACT
Aligning with Crump and colleagues' (2024) conclusions on cataract surgery, this article champions a level playing field for expanding surgical capacities for straightforward surgeries. It is agnostic toward for-profit or not-for-profit models. It argues for experimenting with new ambulatory facilities to meet urgent needs, emphasizing Ontario's successful two-decade experience with models such as the Kensington Eye Institute. The discussion advances a three-tiered pricing framework, advocating for transparent, structured pricing to reduce wait times and improve public health outcomes. This approach seeks to balance annual commitments, quarterly adjustments and spot market needs, promoting innovation, cost-efficiency and quality care.

Economic evaluations are tools for assessing emerging technologies and a complement for decision-making in healthcare systems. However, this topic may not be familiar for doctors and academics, who may be confused when interpreting the results of studies using these tools. Cataract is a disease which has received special attention in healthcare systems due to its high incidence, the great impact that it could have on patients' quality of life, and the fact that it can be definitively solved in almost all cases through cataract surgery. Historically, economic evaluations in cataract surgery have been conducted for many purposes by simply assessing whether the surgery is cost-effective for specific questions related to the implantation of multifocal intraocular lenses, surgical techniques, optimizing assessments, preventing diseases or complications, etc. Moreover, although there are systematic reviews about cataract surgery and narrative reviews introducing the concept of economic evaluations, as far as we know, no previous study has been conducted that synthesizes and integrates evidence coming from both fields. Thus, the purpose of this narrative review is to introduce doctors and academics to economic evaluation tools, to describe how these have been historically applied to cataract surgery, and to provide special considerations for the correct interpretation of economic studies.

Importance: Sustained-release corticosteroids offer the potential of improved compliance and greater patient convenience for anti-inflammatory treatment after cataract surgery. However, they are substantially more expensive than postoperative corticosteroid eye drops, which have historically been standard care. Objective: To examine the use and cost of sustained-release corticosteroids in patients with Medicare who underwent cataract surgery in the US during the temporary pass-through reimbursement program period. Design, Setting, and Participants: This cross-sectional study examined Medicare fee-for-service (FFS) claims from beneficiaries with at least 12 continuous months of Medicare enrollment who underwent at least 1 cataract surgery from March 2019 through December 2021. Patients younger than 65 years, those with missing demographic information, those who had more than 1 cataract surgery on each eye, and those who received more than 1 corticosteroid on the day of surgery were excluded. Cataract surgeries with concurrent use of dexamethasone intraocular suspension 9% or dexamethasone ophthalmic insert were identified. Information on surgeon demographic characteristics and costs of surgery and drugs were extracted. Data were analyzed from June 15 to December 4, 2022. Exposure: Use of dexamethasone intraocular suspension 9% or dexamethasone ophthalmic insert during cataract surgery. Main Outcome Measures: Utilization rate and cost of dexamethasone intraocular suspension 9% and dexamethasone ophthalmic insert among Medicare FFS beneficiaries who underwent cataract surgery. Results: A total of 4â¯252â¯532 cataract surgeries in Medicare FFS beneficiaries (mean [SD] age, 74.8 [5.8] years; 1 730 811 male [40.7%] and 2 521 721 female [59.3%]) were performed by 12â¯284 ophthalmologists (8876 male [72.3%], 2877 female [23.4%], and 531 sex unknown [4.3%]). In all, 34â¯627 beneficiaries (0.8%) received dexamethasone intraocular suspension 9% and 73â¯430 (1.7%) received a dexamethasone ophthalmic insert; the use of both drugs increased over the study period. The mean (SD) Medicare allowed charges for dexamethasone intraocular suspension 9% and dexamethasone ophthalmic insert were $531.47 ($141.52) and $538.49 ($63.79), respectively. Conclusions and Relevance: Despite offering the potential of improved compliance and greater patient convenience, findings of this study suggest that sustained-release corticosteroid use during cataract surgery was low and associated with cost increases to the health care system vs conventional postoperative eye drops. As these new products must be priced high enough to qualify for the Medicare pass-through program, unreasonable cost may have been a deterrent to their use, suggesting that the current Medicare reimbursement rules may not be appropriate for sustained-release postoperative corticosteroids in cataract surgery.

OBJECTIVE: To investigate the cost-effectiveness of implementing iStent inject trabecular bypass stent (TBS) in conjunction with cataract surgery (Cat Sx) in patients with mild-to-moderate glaucoma from a societal perspective in France. The secondary objective was to explore the economic impact of iStent inject TBS in patients who comply to different degrees with their anti-glaucoma medications. METHODS: A previously published Markov model was adapted to estimate the cost-effectiveness of treatment with iStent inject TBS + Cat Sx versus Cat Sx alone over a lifetime time horizon in patients with mild-to-moderate open-angle glaucoma in France. Progression was modeled by health states reflecting increasing stages of vision loss. Disease progression was obtained from the two-year randomized clinical trial assessing safety and effectiveness of both interventions. French specific health-state utilities and costs were obtained through a targeted literature review. Model structure and inputs were validated by French ophthalmologists. Outcomes were expressed as incremental cost per quality-adjusted life-year (QALY) gained. The robustness of results was tested through sensitivity analyses. RESULTS: iStent inject TBS + Cat Sx reduced the number of medications needed and risk of blindness. Incremental cost and QALYs were 75 and 0.065 leading to an incremental cost-effectiveness ratio (ICER) of 1,154/QALY gained. ICER ranged from dominating for non-persistent patients to 31,127 patients fully persistent with their medication regime. Results from one-way sensitivity analysis had a maximum ICER of 29,000 when varying input parameters. iStent inject TBS + Cat Sx had an 86% chance of being cost-effective at a willingness-to-pay threshold of 30,000 per QALY gained. CONCLUSION: Results demonstrate that iStent inject TBS + Cat Sx is a cost-effective intervention for intraocular pressure reduction when compared to Cat Sx alone in France.

INTRODUCTION: In Ethiopia, cataract surgery is mainly provided by donors free of charge through outreach programs. Assessing willingness to pay for patients for cataract surgery will help explain how the service is valued by the beneficiaries and design a domestic source of finance to sustain a program. Although knowledge concerning willingness to pay for cataract surgery is substantive for developing a cost-recovery model, the existed knowledge is limited and not well-addressed. Therefore, the study aimed to assess willingness to pay for cataract surgery and associated factors among cataract patients in Outreach Site, North West Ethiopia. METHODS: A cross-sectional outreach-based study was conducted on 827 cataract patients selected through a simple random sampling method in Tebebe Gion Specialized Hospital, North West Ethiopia, from 10/11/2018 to 14/11/2018. The data were collected using a contingent valuation elicitation approach to elicit the participants' maximum willingness to pay through face to face questionnaire interviews. The descriptive data were organized and presented using summary statistics, frequency distribution tables, and figures accordingly. Factors assumed to be associate with a willingness to pay were identified using a Tobit regression model with a p-value of <0.05 and confidence interval (CI ≠ 0). RESULTS: The study involved 827 cataract patients, and their median age was 65years. About 55% of the participants were willing to pay for the surgery. The average amount of money willing to pay was 17.5USD (95% CI; 10.5, 35.00) and It was significantly associated with being still worker (ß = 26.66, 95% CI: 13.03, 40.29), being educated (ß = 29.16, 95% CI: 2.35, 55.97), free from ocular morbidity (ß = 28.48, 95% CI: 1.08, 55.90), duration with the condition, (ß = -1.69, 95% CI: -3.32, -0.07), admission laterality (ß = 21.21, 95% CI: 3.65, 38.77) and remained visual ability (ß = -0.29, 95% CI (-0.55, -0.04). CONCLUSIONS: Participants' willingness to pay for cataract surgery in outreach Sites is much lower than the surgery's actual cost. Early intervention and developing a cost-recovery model with multi-tiered packages attributed to the neediest people as in retired, less educated, severely disabled is strategic to increase the demand for service uptake and service accessibility.

OBJECTIVE: The analysis aims to assess the cost-effectiveness of cefuroxime (Aprokam®) in the prophylaxis of postoperative endophthalmitis (POE) after cataract surgery compared with the absence of antibiotic prophylaxis from the National Health Fund perspective in Poland. METHODS: We performed a cost-effectiveness and cost-utility analysis using the decision tree and Markov model, respectively, for patients after cataract surgery. The efficacy of Aprokam was 0.21 (95% confidence interval [CI], 0.08-0.55) and is based on the results of the European Society of Cataract and Refractive Surgery study. According to the epidemiological data from Poland, the risk of POE is 0.377%. The costs associated with the Aprokam administration and POE treatment costs were included. We determined the utilities of the health states in the model depending on visual loss due to POE. To determine the uncertainty of estimates parameters, a one-way deterministic and probabilistic sensitivity analysis were performed. RESULTS: Using Aprokam allows avoiding 0.003 POEs per patient. The benefit from the intervention is 0.0007 quality-adjusted life years per patient in the lifetime horizon. The total costs of prophylaxis are higher at about 1.70. The cost of avoiding one POE (incremental cost-effectiveness ratio) is about 569.85. The estimated incremental cost-effectiveness utility ratio is equal to 2427.72/quality-adjusted life-years, and it is significantly lower than the cost-effectiveness threshold in Poland in 2019 (about 7.5% of the threshold). In all scenarios of performed one-way sensitivity analyses, Aprokam is cost-effective. CONCLUSIONS: In Poland, the use of Aprokam is cost-effective, with the estimated incremental cost-utility ratio significantly lower than the cost-effectiveness threshold.

PURPOSE: To assess, from the Canadian public payer perspective, the cost-utility of implanting iStent Inject trabecular bypass stent (TBS) devices in conjunction with cataract surgery versus cataract surgery alone in patients with open-angle glaucoma (OAG) and visually significant cataract. DESIGN: Cost-utility analysis using efficacy and safety results of pivotal randomized clinical trial. PARTICIPANTS: Modeled cohort of patients with OAG (83.1% with mild disease, 16.9% with moderate disease) and visually significant cataract. METHODS: Open-angle glaucoma treatment costs and effects were projected over a 15-year time horizon using a Markov model with Hodapp-Parrish-Anderson glaucoma stages (mild, moderate, advanced, severe or blind) and death as health states. Patients in the mild or moderate OAG health states received implantation of iStent Inject during cataract surgery versus cataract surgery alone. On worsening of visual field defect and optic disc damage, patients could receive selective laser trabeculoplasty and trabeculectomy. We measured treatment effect as reduction in intraocular pressure (IOP) and mean medication use and estimated transition probabilities based on efficacy-adjusted visual field mean deviation decline per month. Healthcare resource utilization and utility scores were obtained from the literature. Cost inputs (2017 Canadian dollars [C$]) were derived using the Ontario Health Insurance Plan, expert opinion, medication claims datasets, and Ontario Drug Benefit Formulary medication consumption costs. We conducted deterministic and probabilistic sensitivity analyses to examine the impact of alternative model input values on results. MAIN OUTCOME MEASURES: Incremental cost per quality-adjusted life year (QALY) gained. RESULTS: Compared with cataract surgery alone, TBS plus cataract surgery showed a 99% probability of being more effective (+0.023 QALYs; 95% confidence interval [CI], 0.004 to 0.044) and a 73.7% probability of being cost-saving (net cost, -C$389.00; 95% CI, -C$1712.00 to C$850.70). In 95% of all simulations, TBS plus cataract surgery showed a cost per QALY of C$62 366 or less. Results were robust in additional sensitivity and scenario analyses. CONCLUSIONS: iStent Inject TBS implantation during cataract surgery seems to be cost effective for reducing IOP in patients with mild to moderate OAG versus cataract surgery alone.

Despite significant evidence around barriers hindering timely access to cataract surgery in low- and middle-income countries (LMICs), little is known about the strategies necessary to overcome them and the factors associated with improved access. Despite significant evidence that certain groups, women for example, experience disproportionate difficulties in access, little is known about how to improve the situation for them. Two reviews were conducted recently: Ramke et al., 2018 reported experimental and quasi-experimental evaluations of interventions to improve access of cataract surgical services, and Mercer et al., 2019 investigated interventions to improve gender equity. The aim of this systematic review was to collate, appraise and synthesise evidence from studies on factors associated with uptake of cataract surgery and strategies to improve the uptake in LMICs. We performed a literature search of five electronic databases, google scholar and a detailed reference review. The review identified several strategies that have been suggested to improve uptake of cataract surgery including surgical awareness campaigns; use of successfully operated persons as champions; removal of patient direct and indirect costs; regular community outreach; and ensuring high quality surgeries. Our findings provide the basis for the development of a targeted combination of interventions to improve access and ensure interventions which address barriers are included in planning cataract surgical services. Future research should seek to examine the effectiveness of these strategies and identify other relevant factors associated with intervention effects.

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.

OBJECTIVES: (1) To evaluate the effect of adding a vision dimension ('bolt-on') to the 5-level EQ-5D (EQ-5D-5L) and 3-level EQ-5D (EQ-5D-3L) on their responsiveness, and (2) to compare the responsiveness of a vision 'bolt-on' EQ-5D-3L (EQ-5D-3L + V) with SF-6D and Health Utilities Index Mark 3 (HUI3) to the benefit of cataract surgery. METHODS: Sixty-three patients were assessed before and after their cataract surgery using the EQ-5D-3L, EQ-5D-5L, SF-6D, HUI3, as well as a 3-level and a 5-level vision dimension. Preference-based indices were calculated using available value sets for EQ-5D-3L, EQ-5D-3L + V, EQ-5D-5L, SF-6D, and HUI3, and non-preference-based indices were calculated using the sum-score method for EQ-5D-5L and EQ-5D-5L + V (vision bolt-on EQ-5D-5L). Responsiveness was assessed using the standardized response mean (SRM) and F-statistic. RESULTS: Among preference-based indices, mean changes from pre to post-surgery in EQ-5D-3L + V and EQ-5D-3L indices were 0.031 and 0.018, respectively. The mean changes for EQ-5D-5L, SF-6D and HUI3 indices were 0.020, 0.012 and 0.105, respectively. The SRM (F-statistic) for EQ-5D-3L + V and EQ-5D-3L indices were 0.458 (13.2) and 0.098 (0.6), respectively. The responsiveness of EQ-5D-3L + V was better than EQ-5D-5L, SF-6D; the responsiveness of HUI3 was better than all other measures. Using non-preference-based indices, mean change for EQ-5D-5L + V and EQ-5D-5L were 0.067 and 0.017, respectively. The corresponding SRM (F-statistic) were 0.709 (31.7) and 0.295 (5.4). CONCLUSIONS: Preliminary evidence from our study suggests that a vision 'bolt-on' may increase the responsiveness of EQ-5D-3L and EQ-5D-5L to change in health outcomes experienced by patients undergoing cataract surgery. In absence of the preference-based vision bolt-on EQ-5D-5L index, HUI3 was the most responsive measure.

BACKGROUND: Cataract surgery is one of the most common operations in health care. Femtosecond laser-assisted cataract surgery (FLACS) enables more precise ocular incisions and lens fragmentation than does phacoemulsification cataract surgery (PCS). We hypothesised that FLACS might improve outcomes in cataract surgery compared with PCS despite having higher costs. METHODS: We did a participant-masked randomised superiority clinical trial comparing FLACS and PCS in two parallel groups (permuted block randomisation stratified on centres via a centralised web-based application, allocation ratio 1:1, block size of 2 or 4 for unilateral cases and 2 or 6 for bilateral cases). Five French University Hospitals enrolled consecutive patients aged 22 years or older who were eligible for unilateral or bilateral cataract surgery. Participants, outcome assessors, and technicians carrying out examinations were masked to the surgical treatment allocation until the last follow-up visit and a sham laser procedure was set up for participants randomly assigned to the PCS arm. The primary clinical endpoint was the success rate of surgery, defined as a composite of four outcomes at a 3-month postoperative visit: absence of severe perioperative complication, a best-corrected visual acuity (BCVA) of 0·0 LogMAR (logarithm of the minimum angle of resolution) or better, an absolute refractive error of 0·75 dioptres or less, and unchanged postoperative corneal astigmatism power (≤0·5 dioptres) and axis (≤20°). The primary economic endpoint was the incremental cost per additional patient who had treatment success at 3 months. Primary outcomes were assessed in all randomly assigned patients who met all eligibility criteria (missing data considered as failure). We used mixed logistic regression models or mixed linear regression models for statistical comparisons, adjusted on centres and whether cataract surgery was bilateral or unilateral. The study is registered with ClinicalTrials.gov, NCT01982006. FINDINGS: Of the 907 patients (1476 eyes) randomly assigned between Oct 9, 2013, and Oct 30, 2015, 870 (704 eyes in FLACS group and 685 eyes in the PCS group) were analysed. We identified no significant difference in the success rate of surgery between the FLACS and PCS groups (FLACS: 41·1% [289 eyes]; PCS: 43·6% [299 eyes]); adjusted odds ratio 0·85, 95% CI 0·64-1·12, p=0·250). The incremental cost-effectiveness ratio was 10â703 saved per additional patient who had treatment success with PCS compared with FLACS. We observed no severe adverse events during the femtosecond laser procedure, and most of the complications in the FLACS group related to the primary outcome measures occurred during the phacoemulsification phase or postoperatively. INTERPRETATION: Despite its advanced technology, femtosecond laser was not superior to phacoemulsification in cataract surgery and, with higher costs, did not provide an additional benefit over phacoemulsification for patients or health-care systems. FUNDING: French Ministry of Social Affairs and Health.

PURPOSE: Review scientific literature concerning femtosecond laser-assisted cataract surgery. METHODS: Following databases were searched: CENTRAL (Cochrane Eyes and Vision Trials Register; Cochrane Library: Issue 2 of 12, June 2019), Ovid MEDLINE® without Revisions (1996 to June 2019), Ovid MEDLINE® (1946 to June 2019), Ovid MEDLINE® Daily Update June 2019, MEDLINE and MEDLINE Non-Indexed Items, Embase (1980-2019), Embase (1974 to June 2019), Ovid MEDLINE® and Epub Ahead of Print, in-Process & Other Non-Indexed Citations and Daily (1946 to June 2019), Web of Science (all years), the metaRegister of Controlled Trials ( www.controlled-trials.com ), ClinicalTrials.gov ( www.clinicaltrial.gov ) and World Health Organization International Clinical Trials Registry Platform ( www.who.int/ictrp/search/en ). Search terms/keywords included 'Femtosecond laser' combined with 'cataract', 'cataract surgery'. RESULTS: Based on quality of their methodology and their originality, 121 articles were reviewed, including randomised controlled trials, cohort studies, case-controlled studies, case series, case reports and laboratory studies. Each step of the femtosecond laser-assisted cataract surgery procedure (corneal incisions, arcuate keratotomies, capsulotomy and lens fragmentation) has been discussed with relevance to published outcomes, as well as complication rates of femtosecond laser-assisted cataract surgery, and what we can learn from the larger studies/meta-analyses and the economics of femtosecond laser-assisted cataract surgery within different healthcare settings. CONCLUSION: Studies suggest that the current clinical outcomes of femtosecond laser-assisted cataract surgery are not different to conventional phacoemulsification surgery and it is not cost effective when compared with conventional phacoemulsification surgery. In its current technological form, it is a useful surgical tool in specific complex cataract scenarios, but its usage has not been shown to translate into better clinical outcomes.

PURPOSE OF REVIEW: To review various techniques of manual small incision cataract surgery (MSICS), updates on training residents and fellows, and cost-effectiveness of the surgery. RECENT FINDINGS: Recent population studies estimate that there are 53 million people blind worldwide from cataracts, up from previous figures. This is in part because of population growth and increased life expectancy worldwide. MSICS continues to play a significant role in addressing cataract burden and there is an increasing need to train surgeons in the technique. In response to this need, several modules and rubrics have been developed to assist in the training process. SUMMARY: MSICS has been refined over recent decades with overall outcomes comparable to phacoemulsification (phaco) in certain settings. MSICS cost and efficiency advantages support its ongoing essential role in addressing global cataract blindness.

PURPOSE: To estimate ophthalmologist-level variation in cataract surgery billing and evaluate patient and ophthalmologist characteristics associated with complex cataract surgery coding. SETTING: Cross-sectional study. DESIGN: Retrospective case series. METHODS: Medicare beneficiaries aged 65 years or older who had cataract surgery between January 1, 2016, and December 31, 2017, were included. Billing of cataract surgery as complex versus routine and patient and physician characteristics associated with billing of cataract surgery as complex were evaluated. RESULTS: An estimated 3.5 million cataract procedures were performed on Medicare beneficiaries in 2016 and 2017. Men (odds ratio [OR], 1.79; 95% confidence interval [CI], 1.75-1.82), patients 75 years or older (versus those aged 65 to 74 years: OR, 1.35; 95% CI, 1.33-1.36), and racial minorities (blacks versus whites: OR, 1.80; 95% CI, 1.75-1.85) had increased odds of having cataract surgery coded as complex. The mean rate of coding for complex cataract surgery by individual surgeons (n = 10 075) in the United States was 11.2%, with significant variation. A high-risk clinical diagnosis code was associated with 40.0% of complex cataract surgeries. Adjusted for patient characteristics, ophthalmologists who graduated from medical school within the past 10 years (OR, 1.35; 95% CI, 1.22-1.49) were more likely to code for complex cataract surgery. Higher volume ophthalmologists were less likely to code for complex cataract surgery than low-volume ophthalmologists. CONCLUSIONS: There was marked variation among ophthalmologists in the use of complex cataract surgery. Some variability might represent inaccurate coding and was not entirely based on differences in referral patterns for more complex patients.

In medical services, charge according to the disease is an important way to promote the reform of pricing mechanism, control the unreasonable growth of medical expenses, as well as reduce the burden on patients. Single disease cost forecasting that both identify potential influencing or driving factors and enable better proactive estimation of costs can guide the management and control of medical costs. This study aimed to identify the factors that affect the medical costs of single disease cataract and compare 2 regression models for anticipating acceptable medical cost forecasts. For this purpose, 483 patients with cataract surgery completed in West China Hospital from May 1, 2015, to October 1, 2015, were selected from hospital information system. For cost forecasting, multivariable regression analysis (MRA) and backpropagation neural network (BPNN) were used. Analysis of data was performed with SPSS21.0 and MATLAB2014a software. Total medical costs of patients with cataract (n = 483) ranged from 2015.00 to 13 359.00 CNY, and the mean ± standard deviation is 6292.29 ± 2639.43 CNY. Factors influencing costs of cataract in the MRA include, in importance order, intraocular lens (IOL) implantation (|r|: 0.805, P < .01), doctor level (|r|: 0.644, P < .01), payment source (|r|: 0.554, P < .01), admission status (|r|: 0.326, P < .01), additional diagnosis (|r|: 0.260, P < .01), type of surgery (|r|: 0.127, P < .05), and type of anesthesia (|r|: 0.126, P < .05). In terms of forecasting performance, BPNN (average error: 2.81%) outperforms, yet is less interpretable than MRA (average error: 5.79%). Both MRA and BPNN are technically and economically feasible in generating medical costs of cataract. And some insights on using results of the forecasting model in controlling and reducing disease costs are obtained.

PURPOSE: To perform a cost-utility analysis of 2018 United States real dollars for cataract surgery. SETTING: Center for Value-Based Medicine, Hilton Head, South Carolina, USA. DESIGN: Cost-utility analysis. METHODS: A base-case 14-year cost-utility model using the ophthalmic cost perspective was used. Third-party insurer and societal cost perspectives were also analyzed. Patient outcomes and costs were discounted with net present value analysis at 3% a year. RESULTS: First-eye cataract surgery resulted in a 2.523 quality-adjusted life-year (QALY) gain, a 33.3% patient value gain, and 25.5% quality-of-life gain. Bilateral surgery yielded a 44.1% patient value gain, while second-eye cataract surgery alone conferred an 8.1% value gain. First-eye cataract surgery resulted in a gain of 2.52 QALYs, while second-eye surgery added an incremental gain of 0.81 QALYs. The ophthalmic-cost-perspective average cost-utility ratio was $2526/2.523 = $1001/QALY for first-eye cataract surgery. The societal-cost-perspective average cost-utility ratio was -$370 018/2.523 = -$146 629/QALY. The second-eye ophthalmic-cost-perspective cost-utility ratio was $2526/0.814 = $3101/QALY, while the ophthalmic-cost-perspective cost-utility ratio for bilateral cataract surgery was $5052/3.338 = $1514/QALY. The 14-year U.S. 2018 real-dollar societal-cost-perspective net return on investment for first-eye cataract surgery was $370 018 above the $2526 cost expended for cataract surgery. CONCLUSIONS: Cataract surgery in both the first eye and second eye, when analyzed by standard health economic methodologies, is highly cost-effective. Cataract surgery in 2018 was 73.7% more cost-effective than in 2000.

OBJECTIVE: To evaluate preoperative testing for cataract surgery, implement stakeholder-driven change, and increase the number of patients who arrived for surgery with complete preoperative requirements, for the purpose of delivering safe, high-quality, and cost-effective care for patients. DESIGN: Quality improvement. PARTICIPANTS: Cataract surgery patients, health care staff in Ophthalmology Day Surgery, an Ophthalmology improvement team, the Clinical Section Heads of Ophthalmology and Anaesthesia, Quality Consultants, and members of the Quality Council participated in this study. METHODS: A lean quality improvement approach was used to define and build understanding of the problem. Between July and November 2016, a chart-based reporting system captured all patients who arrived for cataract surgery with expired or incomplete preoperative requirements. A cost analysis was completed, and evidence was reviewed to ensure alignment with best practice preoperative recommendations. RESULTS: On average, 25% (619/2451 over a 17-week period) of patients per day arrived at the Ophthalmology Day Surgery for cataract surgery with incomplete and/or expired physical history forms and ECGs. An improvement team worked to implement a radical improvement idea and relied on an existing questionnaire to ensure patient safety preoperatively. CONCLUSIONS: Based on the literature, best practice guidelines, and a cost analysis, it was decided that patients undergoing routine cataract surgery in Edmonton Zone Hospitals under regional anaesthesia would no longer require physician history and physicals and ECGs. Elimination of the preoperative requirements for all but select high-risk patients meant that 100% of patients who arrived for cataract surgery would not have outstanding presurgery requirements.

BACKGROUND: Cataract is the leading cause of avoidable blindness globally. It is estimated that 89% of people with visual impairment live in low- and middle-income countries where the cost of cataract surgery represents a major barrier for accessing these services. Developing self-sustaining healthcare programs to cater the unmet demands warrants a better understanding of patients' willingness to pay (WTP) for their services. OBJECTIVES: Using a sample of patients visiting eye care facilities in Dhaka, Bangladesh, we estimate WTP for two different cataract extraction techniques, namely small incision cataract surgery (SICS) and phacoemulsification. METHODS: We used contingent valuation (CV) approach and elicited WTP through double-bounded dichotomous choice experiments. We interviewed 556 randomly selected patients (283 for SICS and 273 for phacoemulsification) from five different eye care hospitals of Dhaka. In this paper, we estimated the mean and marginal WTP using interval regression models. We also compared the estimated WTP and stated demand for cataract surgeries against the prevailing market prices of SICS and phacoemulsification. RESULTS: We found the mean WTP of BDT 7579 (US$93) for SICS and BDT 10,208 (US$126) for phacoemulsification are equivalent to 12 and 16 days of household income, respectively. Household income and assets appeared as the major determinants of WTP for cataract surgeries. However, we did not find any significant association with gender, occupation, and household size among other socioeconomic characteristics. Comparisons between market prices and average WTP suggest it is possible to have a viable market for SICS, but a subsidy-based model for phacoemulsification will be financially challenging because of low WTP and high costs. CONCLUSION: Our findings suggest lower-cost SICS can potentially provide patients access to surgeries to treat cataract conditions. Moreover, price discrimination and cross-subsidization could be a viable strategy to increase the service-uptake as well as ensure financial sustainability.
