Devices, systems, and methods for treating and/or determining appropriate prescriptions for one or both eyes of a patient are particularly well-suited for addressing presbyopia, often in combination with concurrent treatments of other vision defects. High-order spherical aberration may be imposed in one or both of a patient's eyes, often as a controlled amount of negative spherical aberration extending across a pupil. A desired presbyopia-mitigating quantity of high-order spherical aberration may be defined by one or more spherical Zernike coefficients, which may be combined with Zernike coefficients generated from a wavefront aberrometer. The resulting prescription can be imposed using refractive surgical techniques such as laser eye surgery, using intraocular lenses and other implanted structures, using contact lenses, using temporary or permanent corneal reshaping techniques, and/or the like.

1. A system for manufacturing an intraocular lens that extends a range of viewing distances without degrading a patient's vision, the system comprising: a sensor that measures a plurality of refractive Zernike coefficients corresponding to aberrations of an eye, wherein the eye includes a pupil, a cornea and a retina;a communication interface that is communicatively coupled to a lens producing assembly; anda processor communicatively coupled to the sensor and the communication interface, wherein the processor:receives, from the sensor, the plurality of refractive Zernike coefficients,defines a prescription of the intraocular lens by combining the plurality of refractive Zernike coefficients with at least one high-order spherical aberration Zernike coefficient, wherein the prescription results in an eye that forms an image of a point source disposed at a viewing distance from the eye at a plane between the cornea and the retina, and the image has a central area with a central intensity surrounded by a peripheral area with a peripheral intensity, the central intensity being higher than the peripheral intensity, andcontrols the lens producing assembly to manufacture the intraocular lens according to the prescription, wherein a surgical implantation of the intraocular lens in the eye results in an altered eye that has a presbyopia-mitigating quantity of high-order negative spherical aberration. 2. The system of claim 1, wherein the sensor is a wavefront sensing system. 3. The system of claim 1, wherein the presbyopia-mitigating quantity of high-order negative spherical aberration is in a range from 0.05 to 0.4 microns of negative spherical aberration across the pupil. 4. The system of claim 3, wherein the presbyopia-mitigating quantity of high-order negative spherical aberration is in a range from 0.1 to 0.3 microns of negative spherical aberration across the pupil. 5. The system of claim 4, wherein the presbyopia-mitigating quantity of high-order negative spherical aberration is in a range from 0.15 to 0.25 microns of negative spherical aberration across the pupil. 6. The system of claim 1, wherein the at least one high-order spherical aberration Zernike coefficient comprises a plurality of high-order spherical aberration Zernike coefficients. 7. A system for manufacturing an intraocular lens that extends a range of viewing distances without degrading a patient's vision, the system comprising: a lens-producing assembly; anda processor communicatively coupled to the lens producing assembly, wherein the processor:receives a plurality of refractive Zernike coefficients corresponding to aberrations of an eye, wherein the eye includes a pupil, a cornea and a retina;defines a prescription of the intraocular lens by combining the plurality of refractive Zernike coefficients with at least one high-order spherical aberration Zernike coefficient, wherein the prescription results in an eye that forms an image of a point source disposed at a viewing distance from the eye at a plane between the cornea and the retina, and the image has a central area with a central intensity surrounded by a peripheral area with a peripheral intensity, the central intensity being higher than the peripheral intensity, andcontrols the lens-producing assembly to manufacture the intraocular lens according to the prescription, wherein a surgical implantation of the intraocular lens in the eye results in an altered eye that has a presbyopia-mitigating quantity of high-order negative spherical aberration. 8. The system of claim 7, wherein the plurality of refractive Zernike coefficients corresponding to the aberrations of the eye are received from a wavefront sensing system. 9. The system of claim 7, wherein the presbyopia-mitigating quantity of high-order negative spherical aberration is in a range from 0.05 to 0.4 microns of negative spherical aberration across the pupil. 10. The system of claim 9, wherein the presbyopia-mitigating quantity of high-order negative spherical aberration is in a range from 0.1 to 0.3 microns of negative spherical aberration across the pupil. 11. The system of claim 10, wherein the presbyopia-mitigating quantity of high-order negative spherical aberration is in a range from 0.15 to 0.25 microns of negative spherical aberration across the pupil. 12. The system of claim 7, wherein the at least one high-order spherical aberration Zernike coefficient comprises a plurality of high-order spherical aberration Zernike coefficients.
