Abstract:
1. A method for slowing progression of myopia or hyperopia of a human patient, comprising: providing contact lenses, the contact lenses comprising a first set of contact lenses and a second set of contact lenses, so that a practitioner can select a contact lens from the second set of contact lenses based on a response of the patient to a contact lens of the first set of contact lenses after at least about 10 minutes of wearing the contact lens of the first set of contact lenses, wherein the response of the patient comprises an accommodative response, an axial ocular elongation measurement, a refractive error correction progression measurement, or a peripheral refraction measurement, or any combinations thereof, to provide an improved visual performance to a human patient wearing the second set of contact lenses compared to the visual performance of the human patient provided by the first set of contact lenses; wherein the first set of contact lenses comprises at least two contact lenses, each contact lens comprising a first refractive power and a second refractive power, the second refractive power providing a defocused retinal image to a human patient at both near and far viewing distances when the contact lens is placed on the eye of the human patient, and wherein the second set of contact lenses comprises at least two contact lenses, each contact lens comprising a first refractive power and a second refractive power, the second refractive power providing a defocused retinal image to a human patient at both near and far viewing distances when the contact lens is placed on the eye of the human patient and effective to slow progression of myopia or hyperopia of the human patient, and the contact lenses of the second set have a different optical design than the contact lenses of the first set.
