Jennifer McMahon and Andrew J. Elder Smith gave a demonstration on the Bausch & Lomb booth. They performed live fittings with the ESP for keratoconic eyes and used Maxim Scleral Lenses.
By taking an ESP measurement they generated height data of the anterior surface of the eye: ocular topography. Based on this ocular topography they chose the right size of the Maxim Scleral Lens.
The ESP proved to be a great help in choosing the best first lens fit.
