Abstract
A cylindrical model eye comprises a plano-cylindrical portion having a plano surface and a first cylindrical surface opposite to the plano surface, a sphero-cylindrical portion having a convex spherical surface and a second cylindrical surface opposite to the convex spherical surface. The second cylindrical surface mates with the first cylindrical surface, and the first cylindrical surface has substantially the same radius curvature radius as the second cylindrical surface.
