Purpose of the Study:

  • To introduce a novel corneal topography screening device.
  • To demonstrate its capability in detecting corneal ectasias.
  • To evaluate its utility in planning refractive procedures based on topography.

Main Methods:

  • Development of a corneal navigator system.
  • Analysis of a database comprising diverse corneal topography patterns.
  • Training a neural network using nineteen corneal topography indices.
