Abstract：
BACKGROUND: To assess the safety and effectiveness of the exclusive use of 27-gauge instruments for all vitreoretinal diseases requiring vitrectomy.
METHODS: In this retrospective study, 1020 consecutive surgeries were performed on 958 eyes of 848 patients using 27-gauge instruments from March 2017 to June 2021. Patients with a minimum follow-up of 3 months were included. Surgical case-mix, best-corrected visual acuity (BCVA), intraocular pressure (IOP), intra- and post-operative complications, and surgery times were recorded.
RESULTS: The study patients were followed up for averagely 11 months. Of the 1020 vitrectomies, 958 were primary procedures. Of the 148 retinal detachment (RD) cases, 138 (93%) required a single vitrectomy. Primary macular hole closure was achieved in 143 of 145 (99%) cases. The average surgical times were 55 and 38 min for RD surgeries and for all other indications, respectively. BCVA improved significantly at the final visit (20/49) compared with the pre-operative visit (20/78) (p < 0.01). IOP was similar at the pre-operative (14.8mmHg) and final (14.3mmHg) visits. Complications recorded include transient hypotony in 39 eyes, iatrogenic retinal breaks in 2 eyes, and a vitreous bleed in 1 other eye.
CONCLUSIONS: This study revealed that 27-gauge vitrectomy instruments can be used for a wide range of indications, with exclusive use in certain settings. The outcomes were similar to other gauges, including for rhegmatogenous retinal detachment, with minimal complications.

摘要：
背景：评估27号仪器对所有需要玻璃体切除术的玻璃体视网膜疾病的安全性和有效性。
方法：在这项回顾性研究中，从2017年3月至2021年6月，使用27号仪器对848名患者的958只眼睛进行了1020次连续手术。纳入最少随访3个月的患者。外科病例混合，最佳矫正视力（BCVA），眼内压（IOP），术中和术后并发症，并记录手术时间。
结果：本研究患者平均随访11个月。在1020例玻璃体切除术中,958是主要程序。在148例视网膜脱离（RD）中，138例（93%）需要一次玻璃体切除术。145例中的143例（99％）实现了原发性黄斑裂孔闭合。RD手术和所有其他适应症的平均手术时间为55和38分钟。分别。与术前访视（20/78）相比，最终访视时的BCVA显着提高（20/49）（p<0.01）。术前（14.8mmHg）和最终（14.3mmHg）就诊时的眼压相似。记录的并发症包括39只眼的短暂性低眼压，2只眼的医源性视网膜破裂，还有一只眼玻璃体出血.
结论：这项研究表明，27号玻璃体切割器械可用于多种适应症，在某些设置中独占使用。结果与其他量表相似，包括孔源性视网膜脱离,最小的并发症。
