摘要
为观察激光治疗儿童人工晶体植入术后后囊混浊的疗效，对３２例患儿（３２只眼）行ＮｄＹＡＧ激光治疗。首先做好患儿工作，争取最大限度地配合；其次术前用短效弱散瞳剂适度扩瞳，并在中心部击穿一个直径为２ｍｍ左右的透明孔，以满足通过眼内的光线。采用ＮｄＹＡＧ激光治疗，从低能量（０．４ｍＪ）开始，视个体反应递增，每次治疗总量为２０ｍＪ～３０ｍＪ。结果，３２例视力均恢复到发生后囊混浊前的最佳水平，矫正视力０．１～０．４者２５只眼，０．５～０．８者５只眼，１．０者２只眼，８５％的病例一次击射成功。裂隙灯显微镜检查，未发现人工晶体有明显损伤。激光治疗既可有效地切割混浊的后囊膜，又可避免人工晶体的损伤，疗效满意。
he aim of this study is to evaluate the effects of posterior capsulectomy with Nd∶YAG laser in children with posterior capsule opacification after lens implantation (32 cases). Way of cooperation was informed to children before operation and their pupils were moderately dilated with mild mydriatic. Laser power was set at low energy (04 mJ) and increased gradually according to the individual reaction. Total energy was about 20 mJ-30 mJ per treatment session until the posterior capsule was penetrated centrally about 10 mm in diameter. Visual acuities recovered to their best levels before posterior capsule opacity took place in all cases. Corrected visual acuities were between 01 and 04 in 25 eyes, 05 and 08 in 5 eyes, over 10 in 2 eyes. 85% of the capsules were successfully opened with a single shot, no damage was found in IOL. Our fingings demonstrated that Nd∶YAG laser is very effective in opening the posterior capsule opacity and could avoid damage to IOL.
