摘要
目的 探讨 Q开关 Nd:YAG激光后囊膜切开术治疗后发性白内障的疗效及安全性。方法 回顾性分析行 Q开关 Nd:YAG激光后囊膜切开术后发性白内障患者 16 5例 193眼 ,记录手术前后视力、眼压及并发症 ,并进行统计学分析。结果 (1)后囊膜一次性切开成功率为 10 0 % ,所用激光脉冲数平均 2 4± 2 1.7次 ,激光总能量平均 5 9.3± 6 6 .2 m J;(2 ) 91.2 % (176眼 )视力较术前提高 ;(3) 5 9.6 % (115眼 )出现一过性眼压升高 ;手术前后眼压变化与是否植入人工晶状体、所用激光脉冲数以及白内障手术与后囊膜切开术间隔时间有关 ;(4) 19.3% (32眼 )出现人工晶状体损伤。结论 Q开关 Nd:YAG激光后囊膜切开术治疗后发性白内障安全、有效 ,但应严格掌握手术适应证 ,并合理选择激光参数。
Objective To assess the efficacy and safety of Q-switch Nd:YAG laser posterior capsulotomy in treatment of after cataract.Methods Nd:YAG laser posterior capsulotomies were performed in 193 eyes of 165 cases with after cataract.The changes of visual acuity,intraocular pressure and complications were recorded and analyzed retrospectively.Results (1)All the capsulotomies resulted in a central opening of the posterior capsule.24±21.7 impulses in mean were necessary at a total energy of 59.3±66.2mJ.(2)The visual acuity were improved postoperatively in 91.2% eyes.(3)Intraocular pressure increased after YAG laser treatment for a short period of time in 59.6% of the eyes,and the changes of intraocular pressure were correlated with whether intraocular lens implanted or not,laser impulses and time between cataract extraction and capsulotomy.(4)Pits of intraocular lens occurred in 19.3% of the eyes.Conclusion The Q-switch Nd:YAG laser posterior casulotomy is an effective and safe method for treatment of after cataract.But it's necessary to choose cases and to set laser parameters appropriately
