摘　　要：目的探讨儿童外伤性白内障人工晶状体（IOL）不同的植入时机对手术效果的影响。方法134例（134眼）儿童外伤性白内障随机分为两组：A组64眼白内障术中一期植入IOL，B组70只眼白内障术后2—3月二期植入IOL。术后随访6～24个月。结果术后6个月检查矫正视力，A组脱盲率90．6％，脱残率62．5％，B组脱盲率91．5％，脱残率80．0％，两组间脱盲率差异无统计学意义（χ^2=0．026，P〉0．5）。脱残率差异有统计学意义（χ^2=5．03，P〈0．05），术后早、晚期并发症的发生率A组高于B组。其中IOL瞳孔夹持、后囊浑浊，继发性青光眼3种晚期并发症，两组间差异有统计学意义。结论儿童外伤性白内障在白内障术后二期植入IOL，并发症少，视功能恢复较好。Objective To assess and compare the outcomes of primary versus secondary intraocular lens （IOL） implantation for traumatic cataract in children. Methods 134 cases （ 134 eyes） of pediatric traumatic cataract in our hospital were randomly divided into two groups： group A （64 eyes, treated by primary IOL implantation） and group B （70 eyes, treated by secondary IOL implantation）. Follow up was from 6 to 24 months. Results The recovery rate from blindness and disability were 90.6% and 62.5% in group A and 91.5% and 80.0% in group B at 6 months after surgery. There was no significant difference in recovery rate from blindness between two groups （X2 = 0. 026, P 〉 0.5 ）. The recovery rates from disability were significantly different between two groups （χ2 = 5.03, P 〈 0.05 ）. The postoperative complications were severer in group A than group B in early and late stage. The incidences of pupil capture of IOL, posterior capsular opacity and secondary glaucoma were higher in group A than group B. The differences were statistically significant. Conclusion Traumatic cataract in children treated by secondary IOL implantation can have better visual outcomes and less surgical complications compared with primary IOL implantation.
