Abstract
A custom lens device is disclosed as a corrective lens created by a specialized 3D printer. Specifically, a qualified technician working with an ophthalmologist and/or an optometrist combine laboratory measurements of the retina and other eye surfaces, then combine that data with subjective input from the patient's correction to an Amsler grid, to create a custom lens that will un-distort vision which has been distorted (i.e., warped), due to undulations in the retina caused by a number of eye diseases, including, but not limited to, epiretinal membrane and macular degeneration.
Claims19
A custom lens device that is a corrective lens created by a specialized 3D printer, the custom lens device comprising:
- a body component;
- wherein user data is input into a software application which communicates the user data to a 3D printer;
- wherein the 3D printer uses the user data to print the body component;
- and
- wherein the body component is sized and shaped to correct bumps, distortions, and shape of a user's retina;
- wherein a user's retina is scanned and mapped using an A scan (Amplitude Scan) or ultra-wide field retinal imaging to produce the user data used in the 3D printer;
- wherein the user data comprises a degree of myopia or hyperopia, a presence of astigmatism, a light transmittance, a radian of an eyeball of the user, a corneal diameter of the user, a radius of curvature of the eyeball of the user, and a base arc of the eyeball of the user;
- and
- wherein the body component is shaped based on the retinal scan such that concave portions of the body component correspond to convex deformities of the user's retina to reverse warped visual signals caused by an uneven, damaged retina.
A custom lens device that is a corrective lens created by a specialized 3D printer, the custom lens device comprising:
- a body component that is a 3D printed polymer produced on a 3D printer;
- and
- wherein an ophthalmologist or an optometrist combine laboratory measurements of a user's retina and other eye surfaces with data from a user's Amsler grid to produce user data used in the 3D printer;
- wherein a user's retina is scanned and mapped using an A scan (Amplitude Scan) or ultra-wide field retinal imaging to also produce the user data used in the 3D printer;
- wherein the user data is input into a software application which communicates the user data to the 3D printer;
- wherein the 3D printer uses the user data to print the body component;
- wherein the body component is sized and shaped to correct bumps, distortions, and shape of a user's retina based on the retinal scan;
- and
- wherein the body component can be 3D printed with concave parts that correct convex bumps in the user's retina to reverse warped signals to a user's brain caused by an uneven, damaged retina from eye disease;
- and
- further wherein the body component is printed on a ceramic coated substrate comprising an indentation for holding the custom lens.
A method of creating a customized, 3D printed lens for correcting distorted or warped vision, the method comprising the following steps:
- providing a custom lens device comprising a 3D printed lens component;
- measuring a user's retina;
- scanning and mapping a user's retina via amplitude scans or ultra-wide field retinal imaging;
- measuring user data comprising a degree of myopia or hyperopia, a presence of astigmatism, a light transmittance, a radian of an eyeball of the user, a corneal diameter of the user, a radius of curvature of the eyeball of the user, and a base arc of the eyeball of the user;
- enabling a software application to communicate data from the user's retinal measurements, the user data, and mapping to a 3D printer;
- and
- 3D printing a custom lens based on this data, wherein the custom lens is printed on a non-stick coated substrate comprising a dimple for molding the custom lens.
