摘　　要：目的:观察激光治疗儿童人工晶体植入术后后囊混浊的114例患儿120只眼的疗效.方法:当术后出现后囊混浊时应尽早采用激光治疗.在有知觉状态下,争取患儿最大限度地配合.术前用短效弱散瞳药适度扩瞳,并在中心部激穿1个直径为4mm左右的透明孔,以满足通过眼内的光线.从低能量开始(0.4MJ),视个体反应递增,每次治疗总量为20～30MJ.结果:120只眼视力均恢复至发生后囊混浊前的最佳水平,矫正视力0.1～0.4者58只眼,0.5～0.8者54只眼,1.0者8只眼.90%的患儿一次激射成功.利用裂隙灯显微镜检查,未发现人工晶体明显损伤.结论:激光可有效切割混浊的后囊膜,提高患眼视功能,再辅以弱视治疗,对患儿的视功能重建起重要作用.Objective： To observe the curative effectiveness of laser therapy in 114 cases （120 eyes） posterior capsular opacity after intraoeular lenses implantation in children. Methods： When the aftercataract appear , laser therapy should be performed as soon as possible. Under conscious condition, enable the children to cooperate maximally; short effect and mild mydriatic to dilate the pupil, a 4 mm diameter transparent zone in central was made allowing for satisfactory visual performance; Began with low energy （0.4 MJ） and increased progressively according to individual reaction, total energy was 20 -30 MJ every time. Results： All the eyes＇ visual acuity recovered to the best level prior to posterior capsular opacity occurrence, corrected visual acuity 0.1 -0.4 in 58 eyes, 0.5 -0.8 in 54 eyes, 1.0 in 8 eyes. 90 percent were succeed in one laser shot, no intraocular lenses damage was found in slit lamp microscope examination. Conclusion： laser can resect the posterior capsular opacity effectively, improve the visual function of the affected eye. Assisted with amblyopia treatment, laser capsulotomy play an important role in visual function reconstruction in these patients.
