Abstract
(EN) A contact lens for a patient with keratoconus of the cornea, the lens has a substantially continuous arcuate anterior surface and a posterior surface comprising at least three distinct zones: a substantially circular outer zone with a consistent arcuate surface, a central domed zone with greater radius of curvature than said outer zone, said central domed zone of dimensions suitable for accommodating the patient's corneal protrusion, and an arcuate intermediate region connecting said outer zone with said central zone.
