摘 要:目的 评估飞秒激光辅助超声乳化白内障吸除手术的安全性及有效性.方法 病例对照研究.2013年4月至11月在厦门眼科中心行超声乳化白内障手术的患者233例(314只眼),将其分为飞秒激光组(153只眼)及传统超声乳化组(161只眼),比较两组术前一般情况,术中超声乳化能量释放量(CDE)、有效超声时间(EPT)、角膜内皮丢失量、房水闪光值及术后并发症.计量资料采用独立样本t检验;计数资料采用交互列表的卡方或者Fisher确切概率法分析.结果 两组术前一般情况(年龄、性别、眼压、眼轴、角膜曲率、前房深度、核分级)差异无统计学意义(P>0.05).飞秒激光组CDE、EPT分别为4.78%(3.18%~8.88%)和14.05 s(10.07 ~ 20.85 s),小于传统超声乳化组的8.82%(6.01%~19.16%)和23.65 s(18.36 ~ 46.96 s),差异有统计学意义(z=2.30,2.91;P<0.05).飞秒激光组撕囊相对直径和圆形度均较传统超声乳化组更精确(t=2.58,3.92;P<0.05).角膜内皮丢失量在术后1个月时飞秒激光组为73.50(-69.51~ 111.03)个/mm^2,低于传统超声乳化组的118.06(53.55~299.03)个/mm^2,差异有统计学意义(z=2.44;P<0.05).房水闪光值在术后1d激光组18.81(13.32~20.23) ph/ms,传统超声乳化组24.51(16.38~ 32.18) ph/m和1个月时飞秒激光组13.01(9.23~ 16.28) ph/ms,传统超声乳化组18.05(12.37~ 24.97) ph/ms,传统超声乳化组均高于飞秒激光组,差异有统计学意义(z=2.40,2.31;P<0.05).两组术后均无严重并发症出现.结论 飞秒激光辅助超声乳化白内障吸除手术具有较高安全性及有效性,可降低CDE和减少EPT,进而减少角膜内皮损伤和术后前房反应,且撕囊更精确、重复性更好.Objective To evaluate the safety and effectiveness of femtosecond laser-assisted cataract surgery.Methods The interventional case series enrolled 314 eyes undergoing cataract surgery in Xiamen Ophthalmic Center between April and December 2013,patients were randomized to femtosecond laser-assisted cataract surgery(153 eyes) and conventional phacoemulsification cataract surgery(161 eyes).The clincic parameters of preoperation,during operation and postoperation were compared and statistically studied.Quantitative data were analyzed using the analysis of variance,independent t tests.Qualitative datawere analyzed using the crosstabs analysis chi-square test or the Fisher's exact test.Results The patient's demographics parameters(age,gender,IOP,axial length,mean keratometry,AC depth,Cataract grade) did not differ significantly between groups (P〉0.05).The CDE showing 4.78% (3.18%-8.88%)and EPT showing 14.05 s (10.07-20.85 s)in the laser group were significantly lower than the CDE showing 8.82% (6.01%-19.16%) and EPT showing 23.65 s (18.36-46.96 s) in the conventional group (z=2.30,2.91;P〈0.05).The relative diameter and circularity in laser-assisted capusulotomies were significantly more accurate (t=2.58,3.92;P〈0.05).The corneal endothelial cell loss showing 73.50 (-69.51-111.03)/mm^2 was significantly lower in the laser group than the loss of 118.06 (53.55-299.03)/mm^2 in the conventional group 1 month postoperatively (z=2.44;P〈0.05).Postoperative anterial chamber flare was significantly greater in the conventional group at 1 day of 18.81 (13.32-20.23) ph/ms in laser group,24.51(16.38-32.18)ph/m in conventional group and at 1 month of 13.01(9.23-16.28) ph/ms in laser group,18.05(12.37-24.97) ph/ms in conventional group than the laser group (z=2.40,2.31;P〈0.05).There were no severe surgical complications for both groups.Conclusions The femtosecond laser-assisted cataract surgery was effective and safe.It reduced EPT and CDE duri
