To estimate whether implantable collamer lens (V4c ICL) implantation increases the risk of retinal detachment in high myopia comparing with myopes with Rigid Gas-Permeable (RGP) correction. This prospective study was comprised of an ICL group (704 eyes) and an RGP group (628 eyes). Patients were enrolled according to the inclusion criteria and exclusion criteria, then divided into the ICL group and RGP group. Patients in the ICL and RGP groups received V4c ICL implantation and RGP fitting respectively. Retinal details, spherical equivalent refraction (SE), uncorrected distance visual acuity (UDVA), corrected distance vision acutivity (CDVA), axis length (AL), anterior chamber depth (ACD) and other relevant parameters were recorded at different time points. Rhegmatogenous retinal detachment (RRD) morbidity and incidence, RRD morphology and relevant parameters were analyzed. All enrolled patients were followed for 3-6 years. Patients characteristics before the refractive procedure did not show a statistical difference. At the end of the follow up, all the RD cases were RRD. The RRD morbidity of the ICL group and RGP group was 1.99% (14 eyes) and 0.96% (6 eyes) respectively, which did not show statistical difference ( = 0.12). During the first year after refractive procedure, the RRD incidence of the ICL group was 0.85% (6/704), while this number of the RGP group was 0.16% (1/628). It did not show statistical difference ( = 0.08). Compared with RGP fitting, V4c ICL implantation for high myopia correction does not add RRD risk in the long term. V4c ICL implantation is a safe method for high myopia correction.
为评估与接受硬性透气性（RGP）矫正的近视患者相比，植入式角膜胶原晶状体（V4c ICL）植入术是否会增加高度近视患者视网膜脱离的风险。这项前瞻性研究包括一个ICL组（704只眼）和一个RGP组（628只眼）。患者根据纳入标准和排除标准入组，然后分为ICL组和RGP组。ICL组和RGP组的患者分别接受V4c ICL植入和RGP验配。在不同时间点记录视网膜细节、等效球镜度（SE）、未矫正远视力（UDVA）、矫正远视力（CDVA）、眼轴长度（AL）、前房深度（ACD）及其他相关参数。分析孔源性视网膜脱离（RRD）的发病率和发生率、RRD形态及相关参数。所有入组患者均随访3至6年。屈光手术前患者的特征无统计学差异。随访结束时，所有视网膜脱离病例均为RRD。ICL组和RGP组的RRD发病率分别为1.99%（14只眼）和0.96%（6只眼），无统计学差异（P = 0.12）。在屈光手术后的第一年，ICL组的RRD发生率为0.85%（6/704），而RGP组为0.16%（1/628）。无统计学差异（P = 0.08）。与RGP验配相比，V4c ICL植入矫正高度近视在长期内不会增加RRD风险。V4c ICL植入是一种矫正高度近视的安全方法。
