摘　　要：目的 评价飞秒激光辅助晶状体超声乳化联合人工晶状体植入术的安全性及有效性.方法 将621例（685只眼）随机分为飞秒激光组和对照组（传统超声乳化术）.对两组患者术前,术中及术后情况进行比较.结果 两组患者术前一般情况、术前BCVA以及术后3个月UCVA差异均无统计学意义（P〉0.05）.术后1 d以及1周两组UCVA相比较差异有统计学意义.飞秒激光组的有效超声时间缩短25%,平均超声能量下降36%,差异有统计学意义（P〈0.05）.术后3个月时飞秒激光组的内皮细胞丢失率与对照组比较,差异无统计学意义（P〉0.05）.飞秒激光组出现的并发症主要有负压吸引失败（2.28%）、结膜下出血（22.57%）、主切口制作失败（3.43%）、前囊未完全游离（6.57%）、核未开（3.14%）及瞳孔缩小（19.43%）.结论 飞秒激光辅助超声乳化联合人工晶状体植入具有安全性及有效性,能降低有效超声时间和平均超声能量,术后早期恢复效果好.术后视力与传统超声乳化手术相似,差异无统计学意义.术中并发症不影响手术的完成.Objective To evaluate the safety and efficacy of femtosecond laser-assisted phacoemulsification and IOL implantation.Methods Total of 683 eyes of 621cases were randomly divided into femtosecond group and control group（conventional phaco）.The clinical parameters of preoperative,intraoperative and postoperative were compared.Results The patients＇ demographic parameters, BCVA preoperative and 3 months after operation were observed, the difference was not significant between two groups（P〉0.05）.The difference in UCVA at 1 d and 1 week after operation was statistically significant.The effective phaco time（EPT） and avenage ultrasonic energy（AVE） of the femtosecond group all decreased.The difference was statistically significant（P〈0.05）.The loss rate of endothelial cells was lower in the femtosecond group, but the difference was not significant（P〉0.05）.The complication in the femtosecond group included suction break（2.28%）, subconjunctival hemorrhage（22.57%）, main incision failure（3.43%）,decentration of the capsuorhexis（6.57%）,failure to split the lens nucleus（3.14%）and papillary constriction（19.43%）.Conclusion The femtosecond laser-assisted phacoemulsification and IOL implantation is safe and effective.It can decrease the AVE and EPT in the surgery.The efficacy of postoprerative early is firmly restored.The difference in VA after surgery between the two groups is not significant.The complication in the surgery don＇t affect the result of the surgery.
