Screening patients with the corneal navigator.
OBJECTIVE
To present a corneal topography screening device for the detection of corneal ectasias and various refractive procedures based on corneal topography patterns.


METHODS
A database of corneal topography patterns were analyzed and used to "train" a neural network on nine different corneal topography patterns using nineteen corneal topography indices of corneal shape and power.


RESULTS
Sample normal and corneal topographies were recognized correctly.


CONCLUSIONS
The use of the corneal navigator to screen various corneal topographies aids clinical diagnosis.
