We report two cases in which hydrogel lens implants have dislocated posteriorly into the vitreous body following YAG laser capsulotomy. These lenses were placed in the bag in conjunction with a capsulorhexis. A comparison with our results using silicone and poly(methyl methacrylate) implants indicates that this phenomenon has occurred only with hydrogel implants. Analysis of the various parameters associated with the laser capsulotomy procedure suggests that the overall length and design of the hydrogel implants were key factors. Because of the severity of this complication, we have discontinued the use of this type of implant.
我们报告了两例在YAG激光晶状体囊切开术后水凝胶晶状体植入物向后脱位进入玻璃体腔的病例。这些晶状体与撕囊术一起被植入囊袋内。将我们使用硅酮和聚甲基丙烯酸甲酯植入物的结果进行比较表明，这种现象仅发生在水凝胶植入物中。对与激光晶状体囊切开术相关的各种参数进行分析表明，水凝胶植入物的整体长度和设计是关键因素。由于这种并发症的严重性，我们已停止使用此类植入物。
