Visual quality after multifocal intraocular lens (mIOL) implantation has received increased attention. Postoperative residual ametropia, posterior capsule opacification, dry eye, IOL decentration, pupil size, and other factors can affect patient visual acuity. In addition, patient dissatisfaction after mIOL implantation has a relationship with the near add power of mIOLs, which is correlated with vision habits of different patients. Indeed, the actual spectacle plane add power of mIOLs is incompletely consistent with the near add power given by the manufacturers. Ocular biometric parameters such as effective lens position, keratometry, and axial length have effect on the near add power of mIOLs in the lens plane. In this article, the influence of ocular biometric eye parameters on the actual near add power of mIOLs in the lens plane was reviewed.
多焦点人工晶状体（mIOL）植入术后的视觉质量受到了越来越多的关注。术后残留的屈光不正、后囊混浊、干眼症、人工晶状体偏心、瞳孔大小等因素都会影响患者的视力。此外，mIOL 植入术后患者的不满与 mIOL 的近附加力有关，这与不同患者的视觉习惯有关。实际上，mIOL 的实际眼镜平面附加力与制造商给出的近附加力不完全一致。有效晶状体位置、角膜曲率和眼轴等眼部生物测量参数会影响晶状体平面 mIOL 的近附加力。本文综述了眼部生物测量眼参数对晶状体平面 mIOL 实际近附加力的影响。
