两名患者分别在植入后7年和9年时植入了两枚三件式疏水丙烯酸人工晶状体(IOL),原因是眼底可视化差和/或与其浑浊IOL相关的视力出现临床显著下降。除光学显微镜、扫描电子显微镜和能量色散X射线光谱外,首次使用共聚焦激光扫描显微镜观察植入的IOL。临床方面似乎与表面光散射现象相对应,而实验室分析显示IOL光学部中心层有密集反光,表面附近无变化。需要对这些现象进行进一步的研究。
Two three-piece hydrophobic acrylic intraocular lenses (IOLs) were explanted from two patients at 7 and 9 years, respectively, after implantation, because of poor fundus visualisation and/or a clinically significant decrease in visual acuity related to their opacified IOLs. In addition to light microscopy, scanning electron microscopy and energy dispersive X-ray spectroscopy, confocal laser scanning microscopy was used for the first time to observe the explanted IOLs. The clinical aspect seemed to correspond to the phenomenon of surface light scattering, while laboratory analyses showed dense glistenings in the central layer of the IOL optic, which had no change next to the surface. Further studies on these phenomena are needed.
