目的:探讨Q开关Nd:YAG激光后囊膜切开术治疗后囊膜混浊的疗效及安全性。方法:回顾性分析行Q开关Nd:YAG激光后囊膜切开术后囊膜混浊患者165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100%,所用激光脉冲数平均24±21.7次,激光总能量4~451mJ;②91.2%(176眼)视力较术前提高;③59.6%(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;④19.3%(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囊膜混浊安全、有效,但应严格掌握适应证,并合理选择激光参数。
Objective: To investigate the efficacy and safety of Q-switched Nd: YAG laser posterior capsulotomy in the treatment of posterior capsular opacification. Methods: A total of 165 patients (193 eyes) with capsular opacification after Q - switched Nd: YAG laser posterior capsulotomy were retrospectively analyzed. The visual acuity, intraocular pressure and complications were recorded and analyzed statistically. Results: ① The success rate of posterior capsulotomy was 100%, the average number of laser pulses was 24 ± 21.7 and the total laser energy was 4 ~ 451mJ; ② The visual acuity of 91.2% (176 eyes) was higher than that of preoperative; ③59.6 (115 eyes) had transient intraocular pressure (IOP) elevation; the change of intraocular pressure (IOP) before and after surgery was related to the intraocular lens implantation, the number of laser pulses used, and the interval between cataract surgery and posterior capsulotomy; ④19.3% (32 Eye) IOL damage. CONCLUSION: Q-switched Nd: YAG laser posterior capsulotomy is safe and effective in posterior capsular opacification. However, indications should be strictly controlled and the laser parameters should be selected reasonably.
