Ambulatory surgery centers (ASCs) are important providers of ambulatory surgeries. However, little research exists examining the efficiency of ASCs in providing ambulatory surgical services. This study examined the technical efficiency of ASCs that concentrated on performing cataract surgeries, which are among the surgeries most commonly performed in the outpatient setting. This study, based on data from all active ASCs that provided the two most common cataract surgeries in California, found that a large proportion of ophthalmic ASCs were operating at low technical efficiency levels. The amount of slacks in input and output variables was estimated for each ASC, and the mean slacks were reported. The numbers of cataract surgery patients and operating rooms were found to significantly affect the efficiency of ophthalmic ASCs.
门诊手术中心（ASC）是门诊手术的重要提供者。然而，关于ASC提供门诊手术服务效率的研究却很少。本研究考察了专注于进行白内障手术的ASC的技术效率，白内障手术是门诊环境中最常开展的手术之一。本研究基于加利福尼亚州所有开展两种最常见白内障手术的活跃ASC的数据，发现很大一部分眼科ASC的技术效率水平较低。估计了每个ASC投入和产出变量的松弛量，并报告了平均松弛量。发现白内障手术患者数量和手术室数量对眼科ASC的效率有显著影响。
