Abstract
A stereo target corneal topography apparatus and method that uses two differently angled views of a target pattern reflected from a cornea to measure the shape of a cornea using a stereo reconstruction module to reconstruct the shape of a surface of a cornea. The surface elevation, surface slope and/or surface power may be determined without the need to make an initial assumption about the shape of the cornea.
