title: Evaluating the human optical system: corneal topography and wavefront analysis.
abstract: In this article we review three different systems for evaluating the human optical system: placido-disc based corneal topography, scanning slit topography, and wavefront sensors. We briefly describe the principles of each system, and discuss the strengths and weakness. We suspect all three will be used by ophthalmologists in the coming decade.
