Abstract
This application describes a kit of contact lenses comprising two or more contact lenses having a known higher order aberration for each given lens power. By way of example, the higher order aberration may comprise a spherical aberration, a coma aberration, or a trefoil aberration. A practitioner selects a lens from the kit and applies the lens to a patient's eye and measures a residual higher order aberration of the lens-eye system. In cases where the residual higher order aberration exceeds a predetermined magnitude, the practitioner selects a second lens from the kit, applies the second lens to the patient's eye and measures the residual higher order aberration of the lens-eye system.
Claims16
A kit of contact lenses, comprising:
- two or more contact lenses, each lens having a known higher order aberration and lens power;
- wherein the kit includes at least one lens of each incremental low order power;
- wherein the higher order aberration comprises a coma aberration;
- wherein the lenses are configured to have at least one base curve, one diameter, a series of low order aberration lens powers, and an increment of difference in lens power between lenses.
A kit of contact lenses, comprising:
- two or more contact lenses, each lens having a known higher order aberration and lens power;
- wherein the higher order aberration comprises a coma aberration;
- wherein each lens is marked with a code defining its base curve radius, diopter power, the magnitude of the coma aberration and the coma aberration orientation, wherein each lens is marked using laser markings, color markings or silk screen images.
A kit of contact lenses, comprising:
- two or more contact lenses, each lens having a known higher order aberration and lens power;
- wherein the kit includes at least one lens of each incremental low order power;
- wherein the higher order aberration comprises a trefoil aberration;
- wherein the lenses are configured to have at least one base curve, one diameter, a series of low order aberration lens powers, and an increment of difference in lens power between lenses.
A kit of contact lenses, comprising:
- two or more contact lenses, each lens having a known higher order aberration and lens power;
- wherein the higher order aberration comprises a trefoil aberration;
- wherein each lens is marked with a code defining its base curve radius, diopter power, magnitude of trefoil aberration and the trefoil aberration orientation, wherein each lens is marked using laser markings, color markings or silk screen images.
A kit of contact lenses, comprising:
- two or more contact lenses, each lens having two or more known higher order aberrations and lens power;
- wherein the kit includes at least one lens of each incremental low order power;
- wherein the two or more known higher order aberrations include a spherical aberration.
A kit of contact lenses, comprising:
- two or more contact lenses, each lens having two or more known higher order aberrations and lens power;
- wherein the two or more known higher order aberrations include a spherical aberration wherein each lens is marked with a code defining its base curve radius, diopter power, magnitude of spherical aberration, magnitude of coma aberration and the orientation of the coma aberration, wherein each lens is marked using laser markings, color markings or silk screen images.
