中文摘要：

目的：研究飞秒激光白内障与传统超声乳化白内障手术的临床效果差异。方法：将80例白内障患者随机分为观察组和对照组,其中观察组40例47眼,对照组40例44眼。其中观察组患者接受飞秒激光前囊切开辅助治疗,对照组患者接受传统超声乳化治疗。比较两组患者前囊切开直径、囊膜环形张力、囊膜大小和手术时间差异,并比较两组患者术后视力差异、人工晶状体偏移发生率差异。结果：观察组患者前囊切开直径显著低于对照组（P〈0.01）。观察组患者囊膜环形张力显著高于对照组（P〈0.01）。观察组患者囊膜大小显著低于对照组（P〈0.01）。观察组患者手术时间与对照组比较差异无统计学意义（P〉0.05）。观察组患者术后1年内内视力显著优于对照组（P〈0.05）,且1年内人工晶状体偏移发生率显著低于对照组（P〈0.05）。结论 ：飞秒激光辅助白内障手术临床效果优异,可以改善手术效果并以此提高患者视力降低不良反应,具有临床应用价值。

英文摘要：

Objective To study the clinical effects of femtosecond laser surgery and phacoemulsification in patients with cataract. Methods A total of 80 patients were randomly divided into study group and control group. 40 patients with 44 cataract eyes in control group were treated by routine phacoemulsification and 40 patients with 47 cataract eyes in control group were treated by femtosecond laser additionally. The capsulotomy diameter, capsular tension ring, capsule size and operation time difference were compared between two groups. The vision and Intraocular lens decentration rate were compared between two groups. Results The capsulotomy diameter in study group was significantly less than control group （P 〈 0.01）. The apsular tension ring in study group was significantly more than control group（P 〈 0.05）. The capsule size in study group was significantly less than control group（P 〈 0.01）. The operation time in study group was significantly less than control group（P 〉 0.05）. The vision in study group was significantly better than those in control group during a year （P 〈 0.05） and the adverse reaction rate was significantly less （P 〈 0.05）. Conclusion Femtosecond laser combined with phacoemulsification has a great clinical effects which improve patients＇ vision and reduce adverse reaction rate makes it worth for chnical apphcation.
