The researches show that the substrate plays an important role in the development of keratoconus. Cornea substrate's agenesis leads to the reduced solidity, which is possibly related to kearatoconus. There is still a lot to be researched on etilogy and early diagnosis of keratoconus.

虽有研究表明角膜间质的水平在圆锥角膜的发病中起重要作用，角膜间质发育不全，导致角膜的稳固性下降，可能与圆锥角膜形成有关，但对圆锥角膜形成的机理仍不详尽，因此，对圆锥角膜的发病机制及早期诊断的研究具有重要意义。

This paper reported a new method using tangential curvature to establish a mathematical model of the anterior cornea and an analysis of the regularity of the distribution of the asphericity Q. The curvature in the horizontal meridians is a prolate ellipse. The curvature in the vertical meridians is an oblate ellipse. The curvature of the horizontal meridians is important for anterior corneal asphericity.

本研究分析了运用正切曲率半径值建立人眼前表面角膜数学模型的科学性，显示角膜前表面水平子午线方向非球面性趋向于长椭圆，垂直子午线方向非球面性趋向于扁椭圆，说明人眼角膜的非球面性特性主要由水平子午线实现。

Abnormal expression of type Ⅰ～Ⅵ could be found in the onset of illness. The decreasing of collagen could causes the weaken of the stability of stroma lamellar and the cornea shap to conus. The onset of keratoconus is related to collagen

胶原Ⅰ～Ⅵ型的表达在圆锥角膜的发病过程中有明显的变化，胶原成分的减少会导致角膜的机械抵抗力减弱，并使角膜前凸变薄，最终影响角膜的正常形态，圆锥角膜的发病与胶原密切相关。
