Another factor that may be responsible for a lack of agreement between different instruments is that some topography systems derive e-values within a specific zone, such as the Keratron (Optikon, Italy). High-order polynomial descriptors The corneal surface is a complex shape. In order to describe it mathematically high-order polynomial expressions may be used. A study by Howland et al (1992) attempted to describe corneal shape in precisely this manner. , New York), fourth-order polynomial expressions from the Taylor series were fitted to corneal surface coordinates.
In most cases, binding occurs in the superior area of the cornea. The map represents the difference in corneal topography before and after overnight wear with an OK 704CF (Contex, Sherman Oaks, California) trial lens. 24 Topographic sagittal mapof a cornea upon removal of a bound lens. The red area superiorly indicates the primary site of lens binding. The modem approach to orthokeratology lens fitting is based on matching the corneal sag to the sag of the contact lens for reverse geometry lenses.
The corneal elevation / depression (in um) is subtracted from the elevation data of a 9 mm spherical surface. 21 Irregular radial keratotomy (RK) performed on a patient. The axial map (top right) fails to illustrate much of the detail regarding the corneal shape. The tangential map (bottom right) only shows the localized area of steepening following the procedure (often referred to as the RK knee). The anterior elevation and mean powermap (left, top and bottom respectively) are of similar appearance and show the points of greatest elevation on the corneal surface.
