Placido topographer CSO Phoenix had been used to measure 30 peoples corneas with astigmatism 5mm were recorded. The investigation took place at University of West Attica. The results showed that the shape of the cornea varies in the various meridians (e.g. 180° or 90°) and even with oblique meridians (e.g. in the nasal relative to the temporal side) and its curvature correlates with a different equation for each meridian.
