目的：运用Logistic回归分析探讨影响白内障超声乳化术后透明角膜切口(CCI)稳定性的因素。

方法：采用回顾性病例对照研究。收集2018-07/2020-01在鄂尔多斯市中心医院行白内障超声乳化联合折叠型人工晶状体(IOL)植入术患者126例138眼的病历资料。术后1d应用眼前节光相干断层扫描(AS-OCT)对角膜切口进行扫描，根据CCI内口是否存在哆开分为：无内口哆开组84眼，有内口哆开组54眼，分析影响CCI稳定的因素。

结果：术后1d CCI内口哆开发生率54眼(39.1%)，术后1wk为12眼(8.7%)，术后1mo内口全部闭合，切口稳定性均良好，AS-OCT扫描发现内口愈合不良3眼。二元Logistic回归分析结果显示：年龄、切口长度、切口角度、切口内口位置、切口的制作方式和后弹力层脱离有统计学意义(OR=1.102、0.994、27.895、0.127、30.269、6.750，均P<0.05)。

结论：年龄、切口长度、切口角度、切口内口位置、切口的制作方式和后弹力层脱离是影响白内障超声乳化术后CCI稳定性的因素。

METHODS: A retrospective cases-control study was performed. 126 patients(138 eyes)who received phacoemulsification combined with implantation of foldable intraocular lens(IOL)were included in Erdos Central Hospital. Postoperative 1d, all of the CCIs were scanned by anterior segment optical coherence tomography(AS-OCT). According to whether there were presence of inner opening CCIs, the patients were divided into two groups. Group 1: inner opening CCIs(84 eyes)were absent. They were stable. Group 2: inner opening CCIs(54 eyes)were present. The factors affecting the stability of CCI were analyzed.

RESULT: The incidence of internal opening incisions was 39.1%(54/138). It decreased to 8.7%(12/138)at 1wk. One month postoperative, the internal mouths of the incisions were completely closed. The stability of the incisions was good. But AS-OCT scan found 3 cases with poor healing internal incisions. Binary Logistic regression analysis showed that age, incision length, incision angle, location of the internal incision, incision method and descemet's membrane detachment had statistically significant difference(OR=1.102, 0.994, 27.895, 0.127, 30.269, 6.750, all P<0.05).

CONCLUSION:Age, incision length, incision angle, location of the internal incision, incision method and descemet's membrane detachment are the influencing factors of CCI stability after phacoemulsification.
