摘要：

Although the curvature of the general cornea's two principal meridians can be acceptably modelled (within limits) by ellipses, this is insufficient to delineate the overall corneal surface. Applying different assumptions in either case, two corneal models are advanced which interpolate x, y, z points over the whole corneal surface, dependent only on the specifications of the plane curves of the principal meridians.
