Abstract：
OBJECTIVE: To investigate the effect of anterior capsule polishing on postoperative capsule opacification and capsular bend in patients with age-related cataract displaying normal axial length.
METHODS: Eye Hospital of Wenzhou Medical University at Hangzhou.
METHODS: Prospective self-controlled trial.
METHODS: Patients with age-related cataracts aged 56 to 84 years displaying normal axial length were enrolled. Before surgery, a coin-toss method was used to randomly select 1 eye for intraoperative 360 degrees anterior capsule polishing (polishing group); the contralateral eye received no treatment (control group). Capsular bend index (CBI), anterior capsule opacification (ACO), posterior capsule opacification (PCO), and anterior capsule opening area (ACOA) were recorded at 1 week, 1 month, 3 months, 6 months, and 12 months postoperatively using swept-source optical coherence tomography and slitlamp examination.
RESULTS: 21 patients (42 eyes) were enrolled. Within-group comparisons showed that both groups had significant differences in CBI between 1 week and 1 month postoperatively, and between 6 months and 12 months postoperatively ( P < .05). Between-group comparisons revealed a significant difference in CBI at 1 week postoperatively ( P < .05); at 12 months postoperatively, there was a significant difference in ACOA ( P < .05). There were no significant between-group differences regarding ACO or PCO at any timepoint ( P > .05).
CONCLUSIONS: For patients with age-related cataracts and normal axial length, 360 degrees anterior capsule polishing can delay early capsular bag deformation without increasing the risks of ACO and PCO. This approach can also limit contraction of the anterior capsule opening.

摘要：
目的：观察前囊抛光对眼轴长度正常的年龄相关性白内障患者术后囊混浊和囊弯曲的影响。
方法：大学医院。
方法：前瞻性自我对照试验。
方法：纳入年龄相关性白内障患者，年龄56至84岁，眼轴长度正常。手术前,采用抛硬币法随机选择一只眼进行术中360°前囊抛光(抛光组);对侧眼不接受治疗(对照组).囊袋弯曲指数(CBI),前囊混浊(ACO),后囊混浊（PCO），1周时记录前囊开口面积（ACOA），1个月,3个月,6个月,术后12个月使用扫频源光学相干断层扫描和裂隙灯检查。
结果：纳入21例患者（42只眼）。组内比较显示两组术后1周至1个月CBI有显著差异,术后6个月至12个月（P<0.05）。组间比较显示CBI在术后1周有显著差异（P<0.05）；术后12个月，ACOA差异有统计学意义（P<0.05）。在任何时间点，ACO或PCO的组间差异均无统计学意义（P>0.05）。
结论：对于患有年龄相关性白内障且眼轴长度正常的患者，360°前囊抛光可以延迟早期囊袋变形，而不会增加ACO和PCO的风险。这种方法还可以限制前囊开口的收缩。
