摘要
目的:观察Nd:YAG激光对各类白内障术后的后发性白内障的疗效、治疗参数和并发症。方法:对360例382眼各类白内障术后的后发性白内障Nd:YAG激光治疗。观察术后视力及并发症。分1级膜、2级膜和3级膜三组统计激光参数以及分老年性、先天性、并发性和外伤性白内障术后后发性白内障四组统计激光参数进行对照分析。结果:治疗前后最佳矫正视力比较有显著性差异(P<0.05)。老年性组与外伤性组使用的平均激光总能量和平均激光脉冲数比较均有显著性差异(P<0.05)。并发症包括激光治疗后7眼眼压升高(1.8%),人工晶状体损伤26眼(7.7%)。结论:Nd:YAG激光是治疗后发性白内障安全有效的方法。外伤性白内障术后发生后囊膜混浊的病例多为3级膜,Nd:YAG激光治疗时使用单次能量,总脉冲数和激光总能量均大。针对患者的情况选择好激光治疗参数,及时处理术后并发症,能提高治疗的有效性和安全性。
AIM： To investigate the methods, effect and complication of treating different types of after cataract withNd：YAG laser.METHODS： A total of 360 patients 382 eyes with different types of after cataract were treated by Nd：YAG laser. The complication and visual acuity were observed. Laser parameters in three groups of one-level, two-lever, three-level membrane were recorded. Laser parameters in four groups of senile cataract, congenital cataract, complicated cataract and traumatic cataract were statistically analyzed.RESULTS： The best-corrected visual acuity had significant difference after laser treatment（P〈0.05）. The average total laser energy and pulse had significant difference comparing with senile and traumatic group（P〈0.05）. The complications included high intraocular pressure in 7 eyes（1.8%）and the damage of lens in 26 eyes（7.7%）.CONCLUSION：Nd：YAG laser is a safe and effective method for after cataract. Three-level membrane in traumatic cataract is in majority. Single dose energy, total pulse and total laser energy are all big. Different therapic laser parameter according to different patients and timely treatment of complication can improve effect and safety.
