Patent ID: 6926406

Claim:
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 1 , and a second anchor zone having a fourth surface with a curvature AC 2 ; 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 1 , wherein said curvature AC 1 equals said curvature BC plus 5.0; determining said curvature AC 2 , wherein said curvature AC 2 equals said curvature BC plus 4.0; fabricating said each contact lens of said first contact lens pair according to said curvature BC, said curvature RC, said curvature AC 1 and said curvature AC 2 ; 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 1 ′, and a second anchor zone having a fourth surface with a curvature AC 2 ′; 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 1 ′, wherein said curvature AC 1 ′ equals said curvature BC′ plus 5.0; determining said curvature AC 2 ′, wherein said curvature AC 2 ′ equals said curvature BC′ plus 4.0; fabricating said each contact lens of said second contact lens pair according to said curvature BC′, said curvature RC′, said curvature AC 1 ′ and said curvature AC 2 ′; instructing the patient to wear said second contact lens pair for a second specified period of time.
