目得：评价白内障手术后人工晶状体（IOL）的反光和表面光散射对视觉和光学性能的长期影响。方法：对接受标准超声乳化和两种类型的疏水性丙烯酸球形IOL植入术至少5年无并发症的人工晶状体眼进行回顾性研究。根据IOL的当前状况，将参与者分为闪光组、表面光散射组和对照组。结果：共纳入140只眼，均行裸眼视力、矫正远视力、对比敏感度、杂散光、眼内高阶像差、点扩散函数（PSF）和调制传递函数（MTF）等检查。UDVA、CDVA和眩光敏感度在三组之间无显著性差异（P > 0.05）。然而，与对照组相比，闪光和表面光散射组的IOL在无眩光条件下的对比敏感度显著降低。此外，有闪光的眼睛表现出最高的杂散光值（P <0.05），而表面光散射和对照组之间没有发现差异。与对照组相比，球面像差增加，PSF和MTF的平均值下降的glistenings和表面光散射groups.CONCLUSIONS：glistenings和表面光散射往往会损害主观视觉性能，如对比敏感度，并可能影响客观的光学质量，包括杂散光，球面像差，PSF，和MTF。
PURPOSE: To evaluate the long-term effect of glistenings and surface light scattering of intraocular lenses (IOLs) on visual and optical performance after cataract surgery.METHODS: Pseudophakic eyes that underwent standard phacoemulsification and two types of hydrophobic acrylic spherical IOL implantation without complications for at least 5 years were included in this retrospective study. Participants were divided into the glistenings, surface light scattering, and control groups according to the current condition of the IOLs. Then participants received a follow-up examination including uncorrected and corrected distance visual acuity (UDVA and CDVA), contrast sensitivity, straylight, and intraocular higher order aberrations, as well as point spread function (PSF) and modulation transfer function (MTF).RESULTS: A total of 140 eyes were included in the study. UDVA, CDVA, and glare sensitivity were not significantly different among the three groups (P >.05). However, compared with the control group, the IOLs of the glistenings and surface light scattering groups were associated with significantly lower contrast sensitivity under no glare conditions. Furthermore, eye with glistenings exhibited the highest straylight value (P < .05), whereas no difference was found between the surface light scattering and control groups. In contrast to the control group, the spherical aberration increased and the mean values of PSF and MTF decreased in the glistenings and surface light scattering groups.CONCLUSIONS: Both glistenings and surface light scattering tend to impair subjective visual performance, such as contrast sensitivity, and potentially affect objective optical quality, including straylight, spherical aberration, PSF, and MTF.
