目的研究透明晶状体及晶状体核的发育规律，以补充晶状体解剖学理论。方法测量平均２６．２岁的５３例共９７只青年尸眼的晶状体直径（ＬＤ）和晶状体核直径（ＮＤ）及厚度（ＮＴ）并进行统计学分析。结果平均晶状体直径为（９．５２±０．３６）ｍｍ，平均核直径（７．６８±０．５４）ｍｍ，平均核厚度为（２．９±０．４）ｍｍ。晶状体直径、核直径及厚度三者无相关关系，同一人双眼比较，晶状体直径、晶状体核直径及厚度呈直线正相关关系。结论晶状体赤道部形态为小的锯齿状突起，并非平滑的圆环状。左右眼晶状体直径大小基本一致。
Objective To study the development of clear lens and lens nucleus to supplement the lens anatomy theory. Methods The average lens diameter (LD), lens core diameter (ND) and thickness (NT) of 53 young cadaveric eyes of 53 young cadres at 26.2 years old were measured and statistically analyzed. Results The average diameter of the lens was (9.52 ± 0.36) mm, the average diameter of the nucleus was (7.68 ± 0.54) mm and the average thickness of the nucleus was (2.9 ± 0.4) mm. There was no correlation between the diameter of the lens, the diameter of the nucleus and the thickness of the lens. There was a linear positive correlation between the diameter of the lens and the diameter and the thickness of the lens in the same human eyes. Conclusion The shape of the equator of the lens is a small jagged protrusion, which is not a smooth circular ring. The diameter of the left and right eye lenses are basically the same size.
