CORRELATION BETWEEN RADIUS AND ASPHERICITY A.1. ABSTRACT The optical surfaces of the eye are often described in terms of their radius and asphericity. We found that the variation in measured radius and asphericity due to experimental noise is strongly correlated. We show this correlation in experimental corneal elevation data from videokeratoscopy (Atlas, Zeiss) and Scheimpflug topography (Pentacam, Oculus), in non-contact profilometry data of artificial lenses, and in simulations. The effect is a characteristic of conic curves, and not restricted to any experimental device or fitting procedure. A separate analysis of radius and asphericity may estimate incorrectly the statistical significance of the changes of the ocular surfaces. We propose a MANOVA-based statistical analysis that increases sensitivity by a factor of 4. 243
