A new technique for studying the anatomy of the lens and other anterior chamber structures in human eyes obtained post mortem is described. An oblique or side view is achieved by creating a uveoscleral window. This provides a clear three-dimensional view of such structures as the crystalline lens, zonular apparatus, and ciliary body. The crystalline lens is shown to be approximately 4.5 mm thick and 9.5 mm in diameter. The equator of the lens is 0.2 to 0.3 mm from the center of the ciliary body. After removal of lens substance, the capsular bag collapses, its thickness approaches zero, and the total diameter increases to 10.5 mm. Filling of the capsular bag with a viscoelastic material restores the configuration of the lens to its original state. This technique is also useful for demonstrating the dynamics of surgical procedures during cataract operation.
描述了一种用于研究死后获取的人眼晶状体及其他前房结构解剖学的新技术。通过创建一个葡萄膜巩膜窗口可获得斜视或侧视图。这能提供晶状体、悬韧带装置和睫状体等结构清晰的三维视图。晶状体显示约4.5毫米厚，直径9.5毫米。晶状体赤道距睫状体中心0.2至0.3毫米。去除晶状体物质后，囊袋塌陷，其厚度接近零，总直径增加到10.5毫米。用粘弹性材料填充囊袋可使晶状体构型恢复到原始状态。该技术对于展示白内障手术过程中的手术动态也很有用。
