Abstract

We used the Corneal Modeling System(TM), a digital videophotokeratoscope, as an aid in selecting the initial base curve and lens diameter for contact lenses in keratoconus patients. With this instrument we studied corneal topography in 24 keratoconus patients (33 eyes) who were being fit for the first time or who had not worn contact lenses for at least one month prior to our examination. For the purposes of fitting contact lenses, the corneas were classified according to the topographic patterns observed, and appropriate fitting strategies were adopted for each subgroup. Diagnostic lenses and their fluorescein patterns were analyzed for the desired cornea-lens relationship. Topographic analysis of the cornea provided a rational basis for selecting appropriate trial contact lenses for our patients.
