目的探讨儿童白内障超声乳化人工晶体植入术的手术方法及疗效。方法对23例(32眼)儿童白内障行白内障超声乳化人工晶体植入术,术中采用透明角膜隧道切口,植入人工晶体后行一期后囊膜环形撕囊加前部玻璃体切除,术后观察视力、屈光状态、人工晶体位置及后囊情况,术后随访时间6个月～2年。结果术中及术后无严重并发症发生,术后所有患者均有不同程度的色素膜炎反应,5眼视轴区人工晶体后有少量膜性渗出,1眼发生一过性高眼压,1眼出现人工晶体瞳孔挟持,所有患者术后矫正视力均较术前有明显提高。结论儿童白内障超声乳化人工晶体植入术是提高视力,防止弱视的最佳选择,一期后囊膜环形撕囊加前部玻璃体切除,可有效防止后发性白内障的发生
Objective To investigate the surgical methods and efficacy of phacoemulsification and intraocular lens implantation in children. Methods Thirty-three children (32 eyes) with cataract received cataract phacoemulsification and intraocular lens implantation. The patients were treated with a clear corneal tunnel incision. Intraocular lens (IOL) was inserted into the posterior capsule and anterior vitrectomy. Visual acuity, refractive status, intraocular lens position and posterior capsule were observed. The follow-up time ranged from 6 months to 2 years. Results There were no serious complications during and after operation. All patients had different degree of uveitis after operation. A small amount of membranous exudation occurred in 5 eyes and a transient ocular hypertension occurred in 1 eye , 1 eye pupil occlusion of intraocular lens, all patients corrected visual acuity were significantly improved compared with preoperative. Conclusion Phacoemulsification and intraocular lens implantation in children is the best choice to improve visual acuity and prevent amblyopia. Posterior capsulotomy combined with anterior vitrectomy can effectively prevent the occurrence of secondary cataract
