BACKGROUND
To report the learning curve of transition from 20-gauge (20 G) conventional vitrectomy to a 20 G sutureless vitrectomy technique.
MATERIALS AND METHODS
This is a retrospective descriptive case study of 32 eyes from 32 consecutive patients who underwent sutureless 20 G pars plana vitrectomy. A 20 G microvitreoretinal blade was introduced, beveled transconjunctivally, slowly, parallel with the limbus, creating a conjunctivoscleral tunnel incision. Study participants were divided into three groups, and surgical time, induced astigmatism, and complications were compared.
RESULTS
Of 32 consecutive patients, there was no significant difference in induced astigmatism or maneuvering between the early learning curve and other groups. The true learning curve was the first three patients. There were three cases where suturing the sclerotomy was necessary: one port in each case, three of 32 cases (9.3%), or three of 96 ports (2.9%).
CONCLUSION
There were no significant difficulties in surgical maneuvers while performing 20 g sutureless vitrectomy.
背景
报告从20号（20G）传统玻璃体切除术过渡到20G无缝线玻璃体切除术技术的学习曲线。
材料与方法
这是一项回顾性描述性病例研究，对32例连续患者的32只眼睛进行了20G无缝线玻璃体切除术。引入20G微型玻璃体视网膜刀，经结膜缓慢倾斜，与角膜缘平行，制作结膜巩膜隧道切口。研究参与者分为三组，比较手术时间、诱导散光和并发症。
结果
在32例连续患者中，早期学习曲线组与其他组在诱导散光或操作方面无显著差异。真正的学习曲线是前三位患者。有3例需要缝合巩膜切口：每例1个切口，32例中的3例（9.3%），或96个切口中的3例（2.9%）。
结论
进行20G无缝线玻璃体切除术时，手术操作没有明显困难。
