Keratoconus contact lenses
ESA cone lenses are large-diameter inverse geometry hexacurve contact lenses for Keratoconus. ESA cone lenses have been specially designed to adapt to corneas that have an ectastic area in the center portion.
Contact lenses for keratoconus have to meet the precise needs: provide a good visual quality, ensure compliance with the corneal structures and ensure good comfort. The cone ESA lens are not intended for orthocheratologic modeling of the cone, but arise from the need to reconcile the stability of the lens with a controlled applanation cone to optimize the comfort and quality of vision.
