So the resulting corneal model is noticeably closer to reality than the ellipsoidal model that underlies many known designs of Ortho-K lenses.
Designed by Professor Antonio Calossi of the University of Florence, a world-renowned optometrist and contact lens developer.
Professor Calossi has fulfilled his idea of a safe effect on the cornea in the ESA® lens design. The refractive effect of ESA® lenses is achieved by changing the curvature of the cornea in its middle periphery with no or minimal thinning of the epithelium in the centre of the cornea.
Thus, when using ESA® lenses in myopia, there is an additional important factor that preserves characteristics of the cornea and maintains the health of the eye.
The posterior surface of the lens consists of 6 geometric zones (hyperopic design has 7 zones).

Numerous combinations of these parameters ensure that they fit the vast majority of patients’ corneas. These parameters are open to the practitioner, who can change them as needed.
They can be produced by any laboratory with 2-axis CNC lathes with oscillating tool and FocalPoints® specialty contact lens manufacturing platform.
