The Eye Surface Profiler derives its principal data from sagittal height elevation differences, not curvature. The ESP reconstructs the 3D surface from most of the ocular surface, offering a dramatically better representation of the eye than standard topographers.

Corneo-scleral profilometry is valuable for fitting scleral, corneal gas-permeable (GP), and orthokeratology (OrthoK) lenses, as the contact lens industry shifts to an elevation-based approach. Elevation data also plays a critical role in ensuring precise, successful, empirical designs for soft and hybrid lenses.
