Abstract

Placido topographer CSO Phoenix had been used to measure 30 peoples corneas with astigmatism < 0.50 Dc (University of West Attica) and their refractive maps were taken. The refractive power map was used with measurements taken at the horizontal (180°), vertical (90°), and oblique axes (45° and 135°) for each of these 30 people. The keratometric measurements for > 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.
