Abstract :
The authors present a brief overview of the surface to be measured (the cornea of the eye), review the current state of the technology designed to measure the corneal topography, and define the outstanding issues of current significance. The topics discussed include: eye movements; fundamental operating principles of new systems; videokeratographic systems; fundamental limitations of the operating principles; limitations of the hardware; data analysis; display; measurement accuracy of current systems
