目的：观察使用改良微创23G联合20G三通道硅油取出手术的疗效。

方法：回顾性研究，收集2018-03/2019-09在晶亮眼科医院住院的硅油眼患者32例32眼，行玻璃体切割常规三通道切口，做23G的灌注、照明及20G的10：00位抽吸切口，使用23G微创玻璃体切割仪联合改良的18G取硅油针头抽取硅油，检查手术后1d，1wk，1、3mo的BCVA、眼压、疼痛舒适度、硅油残留、脉络膜脱离、视网膜脱离等情况。

结果：所有32例患者手术顺利，手术过程中眼内压平稳，无波动。抽取硅油时间约10～15min，术中无并发症发生； 术后随访3mo，均未发现玻璃体积血、脉络膜脱离、视网膜再脱离。

结论：改良微创23G联合20G三通道硅油取出方法简单、安全、平稳、有效。

METHODS: The objects of study were 32 patients with silicone oil eyes hospitalized in Jingliang Eye Hospital from March 2018 to September 2019. Enrolled patients were provided with standard three-channel incision for vitrectomy, with 23G perfusion and lighting as well as 20G suction incision at 10 o'clock. Silicone oil removal was then conducted by using minimally invasive 23G vitrectomy instrument and modified 18G needle. Further examination was performed to observe the best corrected visual acuity(BCVA), intraocular pressure, pain comfort, silicone oil residue, choroidal detachment, retinal detachment 1d, 1wk, 1mo and 3mo after operation.

RESULTS: All the 32 patients underwent operation successfully, and there was stable intraocular pressure and no fluctuation during operation. The removal time of silicone oil was about 10-15min, and no complications occurred intraoperatively. Postoperative 3-month follow-up 3 revealed no vitreous hemorrhage, choroidal detachment and retinal reattachment.

CONCLUSION: The modified minimally invasive 23G combined with standard 20G three-channel vitrectomy is simple, safe, stable and effective for silicone oil removal.
