与其他屈光手术相比，有晶状体眼后房型人工晶状体(ICL)植入手术是目前屈光手术中最受欢迎的术式之一。ICL手术具有可逆性、高清视觉效果、不会改变角膜解剖结构等优点。目前临床最常用的是V4c型有中央孔型晶状体，围手术期不需要行虹膜激光打孔术。且术后可获得良好的裸眼视力，然而，部分患者术后早期可能出现视觉干扰现象，如光晕、眩光等，尤其在暗光环境下可能影响视觉舒适度。文章针对ICL V4c术后高阶像差(HOA)、调制传递函数(MTF)、对比敏感度(CS)等视觉质量指标及影响因素进行综述，并探讨术后视觉质量可能存在的相对缺陷与相关机制。

[Abstract]
Compared to other refractive surgeries, the implantable collamer lens(ICL)implantation procedure has become one of the most popular surgical options in refractive surgery. ICL surgery offers advantages such as reversibility, high-definition visual outcomes, and preservation of the corneal anatomical structure. The V4c model, which features a central port, is currently the most widely used in clinical practice and eliminates the need for peripheral iridotomy during the perioperative period. Although excellent uncorrected visual acuity can be achieved postoperatively, some patients may experience visual disturbances in the early postoperative period, such as halo and glare, which may affect visual comfort particularly under low-light conditions. This article reviews visual quality metrics after ICL V4c implantation, including higher-order aberrations(HOA), modulation transfer function(MTF), and contrast sensitivity(CS), along with influencing factors, and discusses potential relative deficits in postoperative visual quality and their underlying mechanisms.
