The aim of this review is to summarize the optical quality results in patients following the implantation of the V4c implantable collamer lens with a central port (ICL, STAAR Surgical Inc.). A literature search in several databases was carried out to identify those publications, both prospective, retrospective and/or comparative with other refractive surgery procedures, reporting optical outcomes of patients who were implanted with the V4c ICL model. A total of 17 clinical studies published between 2012 and 2021 were included in this review. A detailed analysis of the available data was performed including number of eyes, follow-up and preoperative spherical equivalent. Specifically, the review focused on several optical parameters including higher-order aberrations (HOAs), modulation transfer function (MTF) cut-off frequency and Strehl ratio. This review encompassed a total of 817 eyes measured using different optical devices based on Hartmann-Shack, retinal image quality measurement and ray-tracing technologies at different follow-ups. The outcomes found in this review lead us to conclude that the ICL V4c model provides good optical quality, by means of different metrics, when implanted.

具有中央端口的后腔有晶状体植入式角膜夹层镜片的体内光学质量

本综述的目的是总结患者在植入具有中央端口的 V4c 可植入式眼透镜（ICL，STAAR Surgical Inc.）后的光学质量结果。在几个数据库中进行了文献检索，以确定这些出版物，包括前瞻性、回顾性和/或与其他屈光手术程序的比较，报告了植入 V4c ICL 模型的患者的光学结果。本综述共纳入 2012 年至 2021 年间发表的 17 项临床研究。对可用数据进行了详细分析，包括眼数、随访和术前等效球镜。具体来说，审查重点关注几个光学参数，包括高阶像差 (HOA)、调制传递函数 (MTF) 截止频率和斯特列尔比。这篇综述包括在不同的随访中使用基于 Hartmann-Shack 的不同光学设备、视网膜图像质量测量和光线追踪技术测量的总共 817 只眼睛。本次审查发现的结果使我们得出结论，ICL V4c 模型在植入时通过不同的指标提供了良好的光学质量。
