Abstract

Purpose: This study aimed to describe a novel technique of direct anterior chamber (AC) air replacement (DACAR) for the management of Descemet stripping automated endothelial keratoplasty (DSAEK) in postvitrectomized eyes and eyes with previous glaucoma surgery.

Methods: DACAR was performed after a corneal donor graft was transplanted through a wound using the pull-through technique. DACAR involves stabilizing the graft with forceps while introducing air into the AC via an infusion cannula to ensure complete air exchange. The air was maintained in the AC at all times using a vitrectomy machine. The air pressure was maintained at 30 mm Hg for 15 minutes.

Results: The DACAR technique was performed in 34 patients, and conventional pull-through technique DSAEK was performed in 32 high-risk patients. The DACAR group had shorter DSAEK surgical procedures (P = 0.009) and a lower incidence of corneal graft detachment in the early postoperative period (P < 0.001) than the conventional DSAEK group.

Conclusions: DACAR is performed in patients having previously undergone vitrectomy or glaucoma surgery to prevent corneal graft detachment during the early postoperative period and to reduce the length of surgery.

直接前房空气置换法在角膜内皮剥离自动角膜移植术中的疗效。

目的：本研究旨在描述一种新的直接前房（AC）空气置换（DACAR）技术，用于玻璃体切除术后和既往青光眼手术的眼睛的Descemet剥离自动内皮角膜移植术（DSAEK）的治疗。方法：采用拉穿技术将供角膜通过创面移植后进行DACAR。DACAR包括用镊子稳定移植物，同时通过输注套管将空气引入AC以确保完全的空气交换。通过玻璃体切割机保持空调内的空气。气压维持在30毫米汞柱15分钟。结果：34例患者采用DACAR技术，32例高危患者采用DSAEK常规拉通技术。与常规DSAEK组相比，DACAR组的DSAEK手术时间较短（P = 0.009），术后早期角膜移植脱离的发生率较低（P < 0.001）。结论：对玻璃体切除术或青光眼手术的患者行DACAR，可防止术后早期角膜移植物脱离，缩短手术时间。
