Abstract： 目的观察钕-钇铝石榴石(neodymium-yttrium aluminum garnet,Nd:YAG)激光玻璃体松解术对人工晶状体植入手术后前部玻璃体混浊的治疗效果. 方法对裂隙灯显微镜联合光相干断层扫描(optical coherence tomography, OCT)和B型超声检查确诊的人工晶状体植入手术后前部玻璃体混浊患者47例49只眼,采用Nd:YAG激光行晶状体后囊切开的同时进行前部玻璃体切开及松解,观察激光治疗前后的视力变化、前部玻璃体混浊的改善情况以及治疗后的并发症. 结果 49只眼中,前部玻璃体混浊伴有晶状体后囊混浊46只眼,晶状体后囊无明显混浊3只眼.Nd:YAG激光玻璃体松解术后视力均有改善,与术前比较差异有显著性的意义(t=32.50,P=0.007).激光松解术后15 min前部混浊的玻璃体形成透明区者21只眼,占42.86%;24 h内形成透明区者47只眼,占95.92%;2只眼在术后7 d透明区小于瞳孔接受了第2次激光治疗.全部患眼术中和术后无并发症发生. 结论人工晶状体植入手术后视力缓慢下降的患者,除考虑有后发障外,还应注意是否有前部玻璃体混浊的存在.Nd:YAG激光晶状体后囊切开联合前部玻璃体松解是治疗人工晶状体植入手术后前部玻璃体混浊的有效方法.
