KeraSoft Thin is a completely customizable soft lens design for healthy management of Keratoconus and most Irregular Cornea conditions. Made exclusively in the Definitive Silicone Hydrogel 74% water content material, this lens is for quarterly replacement.

A Diagnostic 8-lens Fitting Set is essential to the fitting process of the KeraSoft Thin lens. Although various instruments can be used to understand the central corneal shape, they give limited information relating to the cornea scleral junction and beyond. Thus, it is not possible to fit the lens empirically from topography maps or other measurements.

A successful fitting KeraSoft Thin lens is based on observing the characteristics of the lens behavior on eye using the MoRoCCo VA technique; Movement, Rotation, Centration, Comfort and Visual Acuity. All of these characteristics are related to each other and have EQUAL importance when assessing the fit on an irregular cornea.

  • All stages of Keratoconus
