目的 探讨儿童白内障人工晶体植入术, 术后并发症及处理.方法 89 例100 眼先天性和外伤性白内障, 年龄1 岁9 个月至14 岁, 行针吸并后房型人工晶体植入, 术后随访3 个月至4 年.结果 除4 例患儿不合作, 其余患儿术后视力均较术前有所提高, ≥0－5 为55 例, 术后并发症主要为后囊混浊, 14 眼行二期后囊切开或YAG 激光治疗.其它并发症包括色素膜炎、人工晶体偏心或移位、不可逆瞳孔散大、继发性青光眼及一过性高眼压.结论 人工晶体植入术是目前儿童白内障较为理想的复明手段, 但应慎重选择病人及妥善处理术后并发症, 更为重要的是进行长期随访观察“,”Objective To study the effects of intraocular lens (IOL) implant surgery in congenital and traumatic cataract of children. Methods Extracapsular cataract extraction (ECCE) and posterior chamber IOL operations were performed in 89 cases (100 eyes) of congenital and traumatic cataract, aged from 21 months to 14 years old. The follow up ranged from 3 months to 4 years. And the postoperative complications and management were also discussed. Results The visual acuity was improved in most cases after surgery except 4 in which the follow up was lost. 60% of the eyes achieved a visual acuity of 6/12 or better. The main complication was posterior capsule opacification, accounting for 97%. Secondary capsulotomy or YAG laser treatments in 14 eyes were performed. The incidence of other complications accounted for 26% including uveitis, dislocation of IOL, atonic pupil, secondary glaucoma and temporary high intraocular pressure. Conclusions IOL implantation is a better method for the recovery of visual acuity in pediatric cataract at present, but the postoperative complications should be well managed. A long term follow up is required.
