Each of the patients was diagnosed with keratoconus based on a collective assessment of refraction examination, slit-lamp anterior segment examination, and corneal topography.
The approach was considered radical at the time for its recommendation that corneal topography - that is, the external shape of the cornea, which is the clear "window" at the front of the eye - be considered together with the patient's refraction in the surgical planning of refractive surgery.
Eyes were diagnosed with keratoconus if they had at least one slit-lamp finding of anterior corneal bulging, stromal thinning, conical protrusion of the cornea at the apex, Fleischer ring, or Vogt striae and/or corneal topography findings characteristic of keratoconus such as asymmetric bow-tie pattern with or without skewed axes and inferior-superior power asymmetry.
Using a trained Support Vector Machine, or SVM algorithm, Pathfinder II displays the probability (From 0 to 99%) that the corneal topography matches each of the categories established in the PathFinder II clinical study database.
