PURPOSE
To introduce a new non-trocar system for 25-gauge transconjunctival pars plana vitrectomy (PPV).
DESIGN
Study of a new surgical instrument.
METHODS
This new non-trocar system for 25-gauge transconjunctival PPV consists of a contact lens ring featuring four projections containing 1.0-mm diameter holes located 3.0 mm from the ring edge, a wedge-shaped 25-gauge infusion cannula, and two plugs.
RESULTS
The ring is fixed with 7-0 silk sutures at the 3- and 9-o'clock positions on the limbus. Using the 25-gauge needle, three conjunctival and scleral incisions (n = 3) are made at the projection holes located inferotemporally, superonasally, and superotemporally. No intra- or postoperative complications were encountered in 14 patients treated by this non-trocar 25-gauge transconjunctival PPV.
CONCLUSION
Using the system introduced here, 25-gauge transconjunctival PPV can be performed without suturing sclerotomies and without intra- or postoperative complications.
目的
介绍一种用于25G经结膜平坦部玻璃体切除术（PPV）的新型非套管系统。
设计
对一种新型手术器械的研究。
方法
这种用于25G经结膜PPV的新型非套管系统包括一个隐形眼镜环，其具有四个突出部，这些突出部包含直径为1.0毫米的孔，孔距环边缘3.0毫米，一个楔形25G灌注套管，以及两个塞子。
结果
该环用7-0丝线缝合固定于角膜缘的3点和9点位置。使用25G针，在颞下、鼻上和颞上的突出部孔处制作三个结膜和巩膜切口（n = 3）。14例接受这种非套管25G经结膜PPV治疗的患者未出现术中或术后并发症。
结论
使用此处介绍的系统，无需缝合巩膜切口即可进行25G经结膜PPV，且无术中或术后并发症。
