AIM: To investigate the influencing factors of clear corneal incision(CCI)after phacoemulsification by Logistic regression analysis. 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
