A method and apparatus for representing an absolute scale for corneal topography

摘要

An absolute scale for representing isodioptric regions of the cornea is described. The scale uses a combination of colors and patterns to represent a scale that represents a large range of values and has sufficient resolution to be clinically useful. The scale uses a small number of colors combined with patterns so that isodioptric regions are easily discerned. The small number of colors facilitates the representation of a large number of dioptric intervals with a small number of bits.
