Abstract:
1. A method for treating myopia of the right and left eyes of a patient, comprising: measuring the topography of the right and left eyes of the patient; providing a first contact lens pair, wherein each contact lens includes a pressure zone having a first surface with a curvature BC, a relief zone having a second surface with a curvature RC, a first anchor zone having a third surface with a curvature AC determining said curvature BC according to the topography measurements; determining said curvature RC, wherein said curvature RC equals said curvature BC plus 12.0; determining said curvature AC determining said curvature AC fabricating said each contact lens of said first contact lens pair according to said curvature BC, said curvature RC, said curvature AC instructing the patient to wear said first contact lens pair for a first specified period of time; providing a second contact lens pair, wherein each contact lens includes a pressure zone having a first surface with a curvature BC′, a relief zone having a second surface with a curvature RC′, a first anchor zone having a third surface with a curvature AC determining said curvature BC′ according to the topography measurement; determining said curvature RC′, wherein said curvature RC equals said curvature BC′ plus 13.5; determining said curvature AC determining said curvature AC fabricating said each contact lens of said second contact lens pair according to said curvature BC′, said curvature RC′, said curvature AC instructing the patient to wear said second contact lens pair for a second specified period of time.
