用于测量角膜地形图的机器通常会产生角膜平均曲率的彩色地形图。(1). 通过对许多正常角膜图的检查,我们发现正常角膜的顶点是弯曲的,而外围是平坦的。相比之下,通过角膜手术变平的角膜通常会在中心变平,在外围变陡(2)。
Machines for the measurement of corneal topography typically produce a colored topographic map of the mean curvature of the cornea. (1). From the examination of a number of such maps of normal corneas it has been found that the normal cornea is most curved at its apex and flatter in the periphery. By contrast, a cornea flattened by corneal surgery will typically be flatter in its center and steeper in the periphery (2).
