Abstract
The need for accurate and precise methods of evaluating the contour of the anterior corneal surface has paralleled the rapid development of keratorefractive surgery. Thus, the suboptimal refractive predictability of procedures such as penetrating keratoplasty, astigmatic keratotomy, and radial keratotomy has provided impetus for the development of techniques for measuring and presenting corneal topography that are essential for understanding changes induced by surgical manipulations of the corneal surface.
