Abstract
Optical devices used to measure thickness are based on specific radii of curvature and indices of refraction. Variations in anterior corneal radii produce negligible changes in the apparent corneal thickness, but changes in the index of refraction cause the cornea to appear thicker or thinner than it actually is.Keywords
