目的：观察飞秒激光辅助超声乳化白内障吸除术(2.4mm微切口)及传统超声乳化白内障吸除术(2.4mm微切口)角膜切口的形态学的改变，评估两者切口的稳定性。

方法：本研究为前瞻性对照研究。患者89例99眼接受白内障手术，根据术式分为两组：飞秒激光组：飞秒激光超声乳化手术组44例49眼； 角膜刀组：2.4mm白内障超声乳化手术组45例50眼。术后应用OCTA评估角膜切口形态改变。

结果：术后1d飞秒激光组未发现外切口哆开，角膜刀组发生率为10%(P<0.05)； 术后1wk，1、3mo两组均未见外切口哆开。术后1wk，1mo飞秒激光组内切口哆开的发生率分别为47%、10%，均低于角膜刀组(术后1wk为68%，1mo为26%)(P<0.05)，术后1d，3mo两组无差异。两组各时间点局部后弹力层脱离的发生率均无差异。

结论：飞秒激光辅助超声乳化白内障吸除术角膜切口早期愈合更好，有效减少早期角膜切口异常构筑的发生。

METHODS: This was a prospective controlled study. A total of 89 cataract patients(99 eyes)who underwent cataract surgery were collected. All patients were divided into two groups: 44 cases(49 eyes)in FLACS group and 45 cases(50 eyes)in CPCS group. Morphology of clear corneal incision was observed by OCTA postoperative.

RESULTS: There was no external wound dehiscence in FLACS group on 1d postoperative, while 10% patients had external wound dehiscence in CPCS group(P<0.05). There were no external wound dehiscence in both groups on 1wk, 1mo and 3mo postoperative. On 1wk and 1mo postoperative, the incidences of internal wound dehiscence in FLACS group(47% of 1wk and 10% of 1mo)were lower than that in CPCS group. There were statistically significant difference(68% of 1wk and 26% of 1mo)(P<0.05). On 1d and 3mo postoperative, there were no significant difference in internal wound dehiscence in both groups. There were no significant differences in descemet membrane detachment(DMD)in both groups.

CONCLUSION: Femtosecond laser-assisted cataract surgery(FLACS)is benefit for wound closure and reducing abnormal incision construction.
