To evaluate whether the air-fluid (A-F) exchange procedure should be recommended for silicone oil (SO) removal surgery.
Consecutive patients that underwent SO removal with or without A-F exchange were requested to complete a questionnaire regarding the presence of floaters and SO residual scores. The medical records of the patients who completed the questionnaire were also reviewed retrospectively for clinical data including best corrected visual acuity, postoperative detachment rate, and intraocular pressure, etc. RESULTS: A total of 124 cases were included, 68 in the A-F (+) group and 56 in the A-F (-). Both groups were similar in demographic data such as age, sex distribution, axial length, and duration of SO tamponade (all P > 0.05). During the process of A-F exchange, a layer of oil film residue can be observed under the microscope, and A-F exchange can remove the residual SO. The ratio of with/without floating in the A-F (-) versus A-F (+) group was 48/8 versus 36/32 (P < 0.01). In addition, the questionnaire survey on the SO residual scores showed a more significant difference in the impact on postoperative visual quality between the two groups.
A-F exchange can effectively reduce residual SO and is recommended as a routine procedure for SO removal surgery.
评估空气-液体（A-F）交换程序是否应推荐用于硅油（SO）取出手术。
对接受或未接受A-F交换的连续SO取出患者进行问卷调查，询问其是否存在飞蚊症及SO残留评分情况。对完成问卷的患者病历进行回顾性分析，收集包括最佳矫正视力、术后视网膜脱离率和眼压等临床数据。结果：共纳入124例患者，A-F（+）组68例，A-F（-）组56例。两组在年龄、性别分布、眼轴长度和SO填充时间等人口统计学数据方面相似（均P>0.05）。在A-F交换过程中，显微镜下可观察到一层油膜残留，A-F交换可去除残留的SO。A-F（-）组与A-F（+）组有/无飞蚊症的比例为48/8与36/32（P<0.01）。此外，关于SO残留评分的问卷调查显示，两组对术后视觉质量影响的差异更显著。
A-F交换可有效减少SO残留，推荐作为SO取出手术的常规操作。
