Scanning electron microscopy of 9 intraocular lenses, removed from patients mainly because of corneal problems, revealed the presence of different types of adhering elements. Independent of clinically significant symptoms of infection, macrophages and/or epitheloid cells and/or granulocytes were observed. On their anterior surface, 3 lenses showed flat cells or cellular remains which are supposed to represent corneal epithelial cells. Membrane fragments were found on 3 other lenses. Most of the polymethylmethacrylate optics of the lenses showed some deformation and/or cracking and to evaluate them some additional studies with new intraocular lenses were performed. High pressure during the preparation procedure for scanning electron microscopy was found to be the cause.
对9枚主要因角膜问题而从患者眼中取出的人工晶状体进行扫描电子显微镜检查，发现存在不同类型的附着成分。无论是否有具有临床意义的感染症状，均观察到巨噬细胞和/或上皮样细胞和/或粒细胞。在它们的前表面，3枚晶状体显示有扁平细胞或细胞残骸，推测为角膜上皮细胞。在另外3枚晶状体上发现了膜碎片。大多数晶状体的聚甲基丙烯酸甲酯光学部件显示出一些变形和/或裂纹，为评估这些情况，对新的人工晶状体进行了一些额外研究。发现扫描电子显微镜制备过程中的高压是导致这些问题的原因。
