Resumen:
In this work we report the design of a conical corneal null-screen
compact topographer, which uses a mobile device to capture null-screen
reflection produced by the posterior corneal surface. The instrument
features a head holder like those of virtual reality headset with the
aim of align the topographer. For corneal topography the device is
calibrated by testing a reference surface where the geometrical
parameters such as the radius of curvature and the conic constant, are
obtained. We present examples of surface topography measurements on some
human corneas.
