方法：采用随机对照研究设计，对62例62眼后房型人工晶状体植入术后发生迟发性前葡萄膜炎的患者随机分为治疗组31例和对照组31例：所有患者人工晶状体前渗出膜达3级或3级以上，治疗组行YAG激光联合常规药物治疗； 对照组行常规药物治疗。所有患者均随访2～3mo。

结果：两组病例经治疗后晶状体前膜均吸收，炎症均消退，视力均有不同程度提高； 两组间的术前、术后视力和眼压变化比较差异无统计学意义(P均>0.05)； 治疗组治愈时间(14.6±2.3d)较对照组(20.4±3.4d)明显缩短(P<0.01)； 两组术后未见严重并发症发生。

结论：YAG激光联合常规药物治疗人工晶状体术后迟发性渗出膜疗效满意。

METHODS: A case control study was adopted and 62 cases(62 eyes)were randomly divided into treatment group(31 cases)and control group(31 cases).All the patients had delayed anterior uveitis after intraocular lens(IOL)implantation with IOL anterior fibrinous membrane reached the grade 3 or above. YAG laser combined with routine medicine were used intreatment group, while conventional medical treatment were performed in control group. All the patients were followed-up for 2-3 months.

RESULTS: Visual acuity were improved at different levels, anterior fibrinous membrane absorbed and inflammation subsided after treatment in both groups., there were no significant differences of visual acuity and intraocular pressure in both two groups between pre-operation and post- operation(all P>0.05). The cure time of the treatment group(14.6±2.3d)was significantly shorter than that of the control group(20.4±3.4d)(P<0.01). No serious complication was found in both two groups postoperatively.

CONCLUSION: The YAG laser combined with routine medicine has a satisfactory curative effect in treating delayed anterior fibrinous membrane after intraocular lens implantation.
