摘　　要：目的:分析中央孔型有晶状体眼后房型人工晶状体(ICL)植入矫正中低度近视的短期有效性、安全性和稳定性。方法:回顾性队列研究。连续纳入2020年7—12月在成都爱尔眼科医院植入V4c ICL晶状体的低度近视患者490例(707眼),均完成术后6个月随访,术前及术后1、3、6个月测量裸眼视力、矫正视力、眼压、拱高和角膜内皮细胞计数,并计算手术安全性、有效性、预测性以及稳定性。术前、术后数据采用配对t检验进行统计分析。结果:随访至术后6个月,患者裸眼视力(-0.076±0.079)LogMAR,手术有效性指数为1.26±0.21,最佳矫正视力(-0.079±0.080)LogMAR,安全指数为1.13±0.18。术后屈光度在±0.5 D以内的占比94.9%,可预测性为99.1%;等效球镜度在术后1个月为(-0.063±0.135)D,术后6个月为(-0.071±0.126)D;角膜内皮细胞计数术前(3078±258)个/mm^(2),术后6个月为(2953±206)个/mm^(2),损失率为(1.05±0.39)%。术后1个月拱高为(498±143)μm,术后6个月为(474±177)μm。ICL更换比例为1.4%。术后未出现严重威胁视力的并发症。结论:ICL植入术(中央孔型,V4c ICL)矫正中低度近视具备良好的效果,手术安全、可靠,且预测性高,患者视力稳定。Objective:To investigate the efficacy,safety and stability outcomes of central-hole posterior chamber collamer phakic intraocular lens implantation in the correction of low-to-moderate myopia.Methods:This retrospective cohort study included 707 eyes of 490 consecutive patientes submitted to posterior chamber collamer phakic intraocular lens implantation that completed a 6-month postoperative follow-up.Efficacy,predictability,stability and safety outcomes were demonstrated preoperatively and at 1,3 and 6 months postoperatively.Results:At 6 months postoperative,uncorrected and best corrected visual acuities were -0.076±0.079 logMAR and -0.079±0.080 logMAR,with an efficacy index of 1.26±0.21 and safety index of 1.13±0.18 respectively;94.9% eyes were within±0.50 D of targeted refraction.The spherical equivalent was -0.063±0.135 D at 1 month and-0.071±0.126 D at 6 months postoperatively.The endothelial cells was 3078±258/mm^(2) preopearatively and 2953±206/mm^(2)at 6 months postoperatively;the mean rate of endothelial cell loss was(1.05±0.39)%.The mean vault were 498±143μm and 474±177μm at 1 month and 6 months after operation respectively.The rate of the ICL exchange was 1.4%.No vision-threatening complications were reported.Conclusion:The posterior chamber collamer phakic intraocular lens implantation demonstrates high refractive efficacy and an excellent safety profile for the correction of lowto-moderate myopia.
