This device creates a topographical map of the inner and outer surfaces of gas permeable contact lenses using the Keratron®, Keratron® Scout and Keratron® Piccolo topographers. The map shows the geometry of the lens and the asphericity in each zone, and allows curvature measurement as well. Therefore, it is possible to detect changes in lens feature or discover the shape of an unknown lens. The device consists of a holder on which the lens is placed with a drop of water. Two separate cradles are used to measure the two surfaces of the lens. The device is placed against the topographer’s...
