方法：选择2012-01/2014-12我院眼科收治的白内障患者42例42眼作为研究对象，按就诊顺序分为对照组与观察组，各21例21眼，对照组给予传统超声乳化手术(phacoemulsification cataract surgery，PCS)治疗，观察组在此基础上加用飞秒激光治疗，记录两组术中有效超声乳化时间(effective phacoemulsification time，EPT)、超声乳化总能量(cumulative dissipated energy，CDE)、液流量、监测眼压、统计角膜内皮丢失率、房水闪辉情况。两组均随访1a，观察远期视力和并发症情况。

结果：观察组总有效率为95%，与对照组的90%对比差异无统计学意义(P>0.05)； 观察组手术时间长于对照组，差异有统计学意义(P<0.05)，但EPT，CDM及液流量均少于对照组，差异有统计学意义(P<0.05)； 两组术后1d眼压对比差异无统计学意义(P>0.05)，观察组房水闪辉、角膜内皮丢失率均低于对照组，差异有统计学意义(P<0.05)； 术后不同时间两组BCVA均较术前上升，差异有统计学意义(P<0.05)，但术后1d，3、6mo，1a观察组BCVA均优于对照组，差异有统计学意义(P<0.05)； 观察组术后并发症发生率为14%，低于对照组的43%，差异有统计学意义(P<0.05)。

结论：FLACS治疗白内障患者手术效果好、术后视力改善明显、并发症发生率低，但手术时间长、费用高。

METHODS: Forty-two cases(42 eyes)of patients with cataract who were treated in the Department of Ophthalmology in our hospital between January 2012 and December 2014 were selected as the study objects. According to the order of treatment, they were divided into control group and observation group, 21 cases in each. The control group was treated with traditional phacoemulsification cataract surgery(PCS). On the basis, the observation group was treated with femtosecond laser. The effective phacoemulsification time(EPT), cumulative dissipated energy(CDE), fluid flow and monitored pressure of the two groups were recorded. The rate of corneal endothelial loss and the situation of Tyndall phenomenon were statistically analyzed. The two groups were followed up for 1a. The long-term visual acuity recovery was observed. The best corrected visual acuity(BCVA)was recorded, and the long-term complications were statistically analyzed.

RESULTS: 1)The total response rate in observation group was 95% while in control group was 90%(P>0.05); 2)the surgery time of the observation group was longer than that of the control group(P<0.05)but EPT was shorter than that of the control group. CDM and liquid flow were less than those of the control group(P<0.05); 3)at 1d after surgery, there was no significant difference in intraocular pressure between the two groups(P>0.05); the rates of Tyndall phenomenon and corneal endothelial loss in the observation group were lower than those in the control group(P<0.05); 4)BCVA of the two groups at different time after surgery were significantly higher than that before surgery(P<0.05). However, at 1d, 3mo, 6mo and 1a after surgery, BCVA of the observation group was better than that of the control group(P<0.05); 5)the incidence of complications in the observation group after surgery(14%)was lower than that in the control group(43%)(P<0.05).

CONCLUSION: The surgical effects of FLACS in the treatment of cataract are good. After surgery, the visual acuity of patients is improved significantly and the incidence of postoperative complications is low. However, the surgery time is long and cost is high, so it is difficult to popularize.
