Measurement of corneal topography in keratoconus
Ophthalmic and Physiological Optics, 1993A new method is described for calculating the topography and curvature of an irregularly shaped cornea, Vertical planes of light are projected onto the cornea and points in x, y, z space are calculated from the light images on the corneal surface. A matrix of points is produced on the cornea and a mathematical surface is filled to them.

An Atlas of Corneal Topography
Archives of Ophthalmology, 1995It was an instant success, but it took decades to achieve. This could describe the subject's importance of this quick-read, how-to-do-it, well-illustrated color atlas on the Eye Sys Laboratories corneal topography device. The quality of the illustrations and easy-to-follow legends that are described nicely in the 10, generally concise chapters, gives ...

1992
Topographical analysis of the cornea has recently emerged as an important part of the ophthalmologist’s diagnostic and therapeutic repertoire. This has occurred for a number of reasons, the most prominent being the recent advances in keratorefractive surgery. To accurately understand and perform this type of surgery, ophthalmologists found that central

Corneal Topography and Irregular Astigmatism
Optometry and Vision Science, 1995The term irregular astigmatism has been used to refer to a variety of types of optical irregularity, although there are no widely recognized quantitative definitions of irregular astigmatism. This paper proposes a particular approach to defining and quantifying irregular astigmatism, and relates this model to blur disc formation.A model of irregular ...
