Abstract
In this work, we design a conical null-screen for testing non-symmetric corneas. We proposed a custom evaluation algorithm in order to calculate the shape of the corneal surface. This data is fitting to a custom non-symmetrical shape surface, taking into account orthogonal polynomials, in order to obtain the geometrical parameters such as the radius of curvature and conical constant. In order to proof our proposal, we perform some corneal topography measurements.
