摘要目的 评价有晶状体眼后房型人工晶状体(PPC-ICL)植入治疗高度近视术后患者双眼视觉的变化.方法 自身对照研究.行PPC-ICL植入术治疗高度近视患者42例,分别于术前和术后6个月行同视机的同时视、双眼融合、远立体视检查,采用颜少明《立体视觉检查图》检测近立体视锐度.采用Fisher's精确概率法对术前和术后6个月以上各参数进行统计分析.结果 术后6个月同时视功能与术前相比差异无统计学意义.远融合范围与远立体视锐度较术前有明显改善,差异有统计学意义(x2=0.357,P＜0.01;x2=0.276,P＜0.05).术后6个月与术前相比中心凹立体视功能和周边立体视功能较前改善,但差异无统计学意义.立体视盲者术后6个月较术前明显减少,差异有统计学意义(x2=0.279,P＜0.05).结论 PPC-ICL植入术后患者同时视、双眼融合、远立体视功能及近立体视功能较术前明显改善.

abstractsObjective To evaluate the changes in binocular vision after phakic posterior chamber implantable collamer lens (PPC-ICL) implantation for high myopia.Methods This self-control study included 84 eyes of 42 patients with high myopia who underwent PPC-ICL implantation surgery.Simultaneous perception,fusion range,and distance and near stereopsis were tested before and 6 months after surgery with a synoptophore and stereogram designed by Yan Shaoming.Results There was no significant difference in simultaneous perception before surgery compared to 6 months after surgery,while the differences in fusion range and distance stereopsis were statistically significant (x2=0.357,P＜0.01 and x2=0.276,P＜0.05).There were no significant differences in foveal stereopsis and peripheral stereopsis before surgery compared to 6 months after surgery,but there was a significant difference in stereo blindness (x2=0.279,P＜0.05).Conclusion Simultaneous perception,fusion range,and distance and near stereopsis after PPC-ICL implantation obviously improved compared to measurements taken before surgery.
