Descemet membrane detachments are not uncommon following cataract surgery, and large and extensive detachments can have an impressive presentation, with severe corneal edema and marked reduction in visual acuity. Traditional treatment regimens have included observation (with the hopes of spontaneous resolution), anterior chamber injections of air or viscoelastic, transcorneal suturing, and even corneal transplantation for persistent cases. During the past few years, intracameral injection with either sulfur hexafluoride (SF6) or perfluoropropane (C3F8) gas has gained increasing acceptance as an efficient and effective treatment option for Descemet membrane detachments. Previously described techniques of gas injection have required corneal and paracentesis incisions; sterile blades, cannulas, and other instruments; and occasionally, an operating room setting. We describe a simple, safe, and effective technique for intracameral gas injection that can be performed by one person at the slitlamp microscope or in a minor operating room with minimal equipment.
在白内障手术后，后弹力层脱离并不少见，大范围的脱离可能表现显著，伴有严重的角膜水肿和视力明显下降。传统的治疗方案包括观察（期望自行消退）、前房注入空气或粘弹剂、经角膜缝合，对于持续性病例甚至进行角膜移植。在过去几年中，前房内注入六氟化硫（SF6）或全氟丙烷（C3F8）气体作为后弹力层脱离的一种有效治疗选择已越来越被接受。先前描述的气体注入技术需要角膜切口和穿刺切口；无菌刀片、套管和其他器械；有时还需要手术室环境。我们描述了一种简单、安全且有效的前房内气体注入技术，该技术可由一人在裂隙灯显微镜下或在配备最少设备的小型手术室中进行。
