Shunmugaranjan et al report that surgical experience is strongly associated with better outcomes after endothelial transplantation.1 The authors used prospective national registry data from over 11 000 endothelial keratoplasties, including Descemet stripping (automated) endothelial keratoplasty (DSEK/DSAEK) or Descemet membrane endothelial keratoplasty (DMEK) to evaluate the impact of surgeon experience. The authors provide compelling evidence that surgical expertise is strongly associated graft survival at 2 years, primary graft failure and need for additional interventions for both DSAEK and DMEK. Visual acuity was better among experienced surgeons post DSEK/DSAEK. In medicine, learning curves were used in the 1980s to describe the uptake of new surgical skills for minimally invasive surgery.2 The ‘learning curve’ describes the fact that a learner’s performance and skills improve over time when the task is repeated. This improvement is quicker in the initial stages and then flattens with subsequent small improvements. In the context of surgical practice, the learning curve is associated with increased risk to patients during the study period when a surgeon is gaining …

学习新的手术技术：我们做得好吗？


Shunmugaranjan 等人报告说，手术经验与内皮移植后更好的结果密切相关。作者使用了来自 11 000 多例内皮角膜移植术的前瞻性国家登记数据，包括后弹力层剥离（自动）内皮角膜移植术 （DSEK/DSAEK） 或后弹力层内皮角膜移植术 （DMEK） 来评估外科医生经验的影响。作者提供了令人信服的证据，证明手术专业知识与 2 年移植物存活率、原发性移植物失败以及 DSAEK 和 DMEK 需要额外干预密切相关。DSEK/DSAEK 后经验丰富的外科医生的视力更好。在医学上，1980 年代使用学习曲线来描述微创手术对新手术技能的吸收。2 “学习曲线”描述了当任务重复时，学习者的表现和技能会随着时间的推移而提高的事实。这种改进在初始阶段更快，然后随着随后的小改进而趋于平缓。在外科实践的背景下，学习曲线与研究期间外科医生获得 ...
