Objective Though one of the most common surgeries, there is limited information on variability of practices in cataract surgeries. ‘Eyefficiency’ is a cataract surgical services auditing tool to help global units improve their surgical productivity and reduce their costs, waste generation and carbon footprint. The aim of the present research is to identify variability and efficiency opportunities in cataract surgical practices globally. Methods and Analysis 9 global cataract surgical facilities used the Eyefficiency tool to collect facility-level data (staffing, pathway steps, costs of supplies and energy use), and live time-and-motion data. A point person from each site gathered and reported data on 1 week or 30 consecutive cataract surgeries. Environmental life cycle assessment and descriptive statistics were used to quantify productivity, costs and carbon footprint. The main outcomes were estimates of productivity, costs, greenhouse gas emissions, and solid waste generation per-case at each site. Results Nine participating sites recorded 475 cataract extractions (a mix of phacoemulsification and manual small incision). Cases per hour ranged from 1.7 to 4.48 at single-bed sites and 1.47 to 4.25 at dual-bed sites. Average per-case expenditures ranged between £31.55 and £399.34, with a majority of costs attributable to medical equipment and supplies. Average solid waste ranged between 0.19 kg and 4.27 kg per phacoemulsification, and greenhouse gases ranged from 41 kg carbon dioxide equivalents (CO2e) to 130 kg CO2e per phacoemulsification. Conclusion Results demonstrate the global diversity of cataract surgical services and non-clinical metrics. Eyefficiency supports local decision-making for resource efficiency and could help identify regional or global best practices for optimising productivity, costs and environmental impact of cataract surgery. All data relevant to the study are included in the article.

提高国际眼健康服务的生产力、成本和环境影响：使用“Eyefficiency”白内障手术服务审计工具来评估白内障手术服务的价值

目的 虽然是最常见的手术之一，但关于白内障手术实践的可变性的信息有限。“Eyefficiency”是一种白内障手术服务审计工具，可帮助全球单位提高手术效率并降低成本、废物产生和碳足迹。本研究的目的是确定全球白内障手术实践中的可变性和效率机会。方法和分析 9 个全球白内障手术设施使用 Eyefficiency 工具收集设施级数据（人员配备、通路步骤、供应成本和能源使用）以及实时时间和运动数据。每个站点的一名负责人收集并报告了 1 周或 30 次连续白内障手术的数据。环境生命周期评估和描述性统计被用来量化生产力，成本和碳足迹。主要成果是对每个地点的每个案例的生产力、成本、温室气体排放和固体废物产生量的估计。结果 9 个参与站点记录了 475 次白内障摘除（超声乳化和手动小切口的混合）。单床位每小时病例数为 1.7 至 4.48，双床位为 1.47 至 4.25。每个病例的平均支出在 31.55 英镑到 399.34 英镑之间，大部分费用来自医疗设备和用品。每次超声乳化平均固体废物介于 0.19 公斤和 4.27 公斤之间，而温室气体的范围从每次超声乳化 41 公斤二氧化碳当量 (CO2e) 到 130 公斤二氧化碳当量。结论 结果表明白内障手术服务和非临床指标的全球多样性。Eyefficiency 支持地方决策以提高资源效率，并有助于确定区域或全球最佳实践，以优化白内障手术的生产力、成本和环境影响。所有与研究相关的数据都包含在文章中。
