PURPOSE
To investigate the relationship between corneal diameter (white to white) (WTW) and the dimensions of the crystalline lens.
SETTING
Private practice, Cincinnati, Ohio, USA.
METHODS
Human cadaver eyes were oriented to allow caliper measurements of the horizontal and vertical corneal diameters (WTW). Globes were sectioned and reoriented so the horizontal and vertical measurements of the crystalline lens were recorded and statistically analyzed.
RESULTS
The mean horizontal corneal diameter was 11.46 mm, approximately 0.8 mm greater than the mean vertical corneal diameter of 10.63 mm. The mean horizontal crystalline lens diameter was 9.28 mm, nearly identical to the mean vertical diameter of 9.30 mm. The correlation between the mean corneal diameter and mean lens diameter was weak, although it was significant. There was no correlation between horizontal dimensions.
CONCLUSION
It was not possible to predict the dimensions of the human crystalline lens using calipers to measure the WTW corneal diameter.
目的
研究角膜直径（白对白）（WTW）与晶状体尺寸之间的关系。
设置
美国俄亥俄州辛辛那提的私人诊所。
方法
将人类尸体眼睛进行定向，以便用卡尺测量水平和垂直角膜直径（WTW）。对眼球进行切片并重新定向，记录晶状体的水平和垂直测量值并进行统计分析。
结果
平均水平角膜直径为11.46毫米，比平均垂直角膜直径10.63毫米大约大0.8毫米。平均水平晶状体直径为9.28毫米，与平均垂直直径9.30毫米几乎相同。平均角膜直径与平均晶状体直径之间的相关性较弱，尽管具有显著性。水平尺寸之间没有相关性。
结论
使用卡尺测量WTW角膜直径无法预测人类晶状体的尺寸。
