目的：探讨人工晶状体(intraocular lens，IOL)Ⅰ期植入和Ⅱ期植入术对外伤性白内障患者术后视力恢复情况和并发症发生情况。

方法：选取2014-01/2016-12我院收治的86例86眼外伤性白内障患者为研究对象进行回顾性研究，按照治疗方式不同分为对照组(接受IOLⅠ期植入术治疗，46眼)和观察组(接受IOLⅡ期植入术治疗，40眼)，观察两组患者手术一般情况、术后6mo视力恢复情况和并发症发生率。

结果：两组患者手术时间、术中出血量、住院时间比较，差异无统计学意义(P>0.05)； 术前两组患者视力优良率比较，差异无统计学意义(P>0.05)； 术后6mo两组患者视力优良率较术前明显提高，差异有统计学意义(P<0.05)，但术后6mo两组患者视力优良率比较，差异无统计学意义(P>0.05)； 两组患者后囊破裂和玻璃体脱出发生率比较，差异无统计学意义(P>0.05)，观察组术后角膜水肿、虹膜睫状体炎、后囊混浊发生率较对照组明显低，差异有统计学意义(P<0.05)。

结论：IOLⅠ期植入和Ⅱ期植入术在外伤性白内障患者应用中，手术一般情况和改善视力恢复方面的效果相当，但Ⅱ期植入术术后并发症发生率更低。

METHODS: Totally 86 patients with traumatic cataract(86 eyes)treated in our hospital from January 2014 to December 2016 were enrolled in the retrospective study, and they were divided into the control group(treated by intraocular lens Ⅰ phase implantation, 46 eyes)and the observation group(treated by intraocular lens Ⅱ phase implantation, 40 eyes). The general situation of surgery, the visual recovery at 6mo after operation and the incidence rate of complications in two groups were observed.

RESULTS:There were no significant differences in surgical time, intraoperative blood loss and hospitalization time between the two groups(P>0.05). There was no significant difference in the excellent and good rate of visual acuity between the two groups before operation between the twogroups(P>0.05). At 6mo after operation, the excellent and good rates of visual acuity in two groups obviously increased(P<0.05), while there was no significant difference in the excellent and good rates of visual acuity at 6mo after operation between the two groups(P>0.05). There was no significant difference between the two groups in the incidence rates of posterior capsule rupture and vitreous body prolapse(P>0.05). The incidence rates of corneal edema, iridocyclitis and posterior capsular opacification in the observation group after operation were significantly lower than those in control group(P<0.05).

CONCLUSION:The effects of IOL Ⅰ phase implantation and Ⅱ phase implantation are similar in patients with traumatic cataract, in terms of the general situation and improvement of visual recovery. However, the incidence of complications after Ⅱ phase implantation is relatively lower.
