Five explanted posterior chamber lenses were examined under the scanning electron microscope to determine the changes. The intraocular time of the lenses was 1 week to 3 years. The polypropylene loops showed superficial cracks in all cases, but only in the curve and the insertion areas. The findings therefore indicated that the morphological changes are more likely caused by mechanical stress than by biological degradation alone.
对五枚摘除的后房型人工晶状体进行扫描电子显微镜检查以确定其变化情况。这些人工晶状体的眼内留置时间为1周到3年。所有病例中的聚丙烯袢均显示有表面裂纹，但仅出现在弯曲处和植入区域。因此，研究结果表明，形态学变化更可能是由机械应力而非单纯的生物降解引起的。
