外伤性白内障Ⅰ期与Ⅱ期人工晶状体植入术的临床疗效比较

Comparison of clinical efficacy betweenⅠphase andⅡphase intraocular lens implantation for the treatment of traumatic cataract

目的比较外伤性白内障Ⅰ期与Ⅱ期人工晶状体植入术的疗效。方法前瞻性病例研究。选取中国人民武装警察部队海警总队医院2016年1月至2018年1月单眼外伤性白内障50例为研究对象,随机分为Ⅰ期人工晶状体植入组(28例)及Ⅱ期人工晶状体植入组(22例),比较两组疗效。结果术后1个月,两组患者视力均优于术前(P<0.05),但两组之间差异无统计学意义(P>0.05)。术后1个月,Ⅱ期组角膜水肿、葡萄膜炎、虹膜后粘连及继发性青光眼发生率均低于Ⅰ期组(P<0.05)。术后1年,Ⅱ期组前房深度、泪膜破裂时间评分高于Ⅰ期组(P<0.05)。Ⅱ期组眼压、角膜荧光染色评分均低于Ⅰ期组(P<0.05)。结论外伤性白内障Ⅱ期人工晶状体植入术并发症发生率较低,远期效果较好。

Objective To compare the clinical efficacy betweenⅠandⅡphase IOL implantation for the treatment of traumatic cataract.Methods Fifty patients of monocular traumatic cataract from Jan.2016 to Jan.2018 in Zhejiang Armed Police Corps Hospital were selected.All cases were randomly divided into two groups.There wereⅠphase IOL implantation group of 28 cases andⅡphase IOL implantation group of 22 cases.The efficacy of the two groups was compared.Results One month after operation,the visual acuity of the two groups were significantly better than that before operation(P<0.05),but there was no significant difference in visual acuity between the two groups(P>0.05).One month after operation,the incidence of corneal edema,uveitis,posterior synechia and secondary glaucoma in II stage group were lower than that in I stage group(P<0.05).One year after operation,the anterior chamber depth and scores of tear film rupture time inⅡphase group were higher than those inⅠphase group(P<0.05),and the intraocular pressure and scores of corneal fluorescence staining were lower than those inⅠphase group(P<0.05).Conclusion IOL implantation,the complication rate of theⅡphase of traumatic cataract for the treatment is lower and the long-term effect is better.
