To present the iridectomy combined with posterior approach anterior chamber gas injection technique for the treatment of extensive Descemet's membrane detachment (DMD), which is a novel surgical approach for the management of DMD after phacoemulsification.
The surgical technique was performed on a 68-year-old female with a history of cataract phacoemulsification surgery and two times of anterior chamber gas injection to treat DMD. After creating a scleral tunnel at 4 o'clock of the limbus, the iris root in that direction was cut off. This was confirmed via an iris root incision indicating that the syringe needle entered the posterior chamber through the scleral tunnel. The anterior chamber was filled about 3/4 with 16% C3F8. After surgery, patients were required to maintain a supine position without pillows. One month post-surgery, the cornea was transparent, DMD had fully recovered, and the best corrected visual acuity improved to 20/20.
The iridectomy combined with a posterior approach anterior chamber gas injection technique can be used as an alternative surgical option for the management of extensive DMD in patients who have undergone several ineffective anterior chamber gas injection surgeries.
介绍虹膜切除术联合后入路前房注气技术治疗广泛的Descemet膜脱离（DMD），这是一种用于治疗白内障超声乳化术后DMD的新型手术方法。
对一名68岁女性实施该手术技术，该患者有白内障超声乳化手术史，并曾两次行前房注气治疗DMD。在角膜缘4点处制作巩膜隧道后，切断该方向的虹膜根部。通过虹膜根部切口证实，注射器针头经巩膜隧道进入后房。前房用16%的C3F8填充约3/4。术后患者需保持去枕仰卧位。术后1个月，角膜透明，DMD完全恢复，最佳矫正视力提高到20/20。
虹膜切除术联合后入路前房注气技术可作为前房注气手术多次无效的广泛DMD患者的替代手术选择。
