Presbyopia correction through negative spherical aberration

An intraocular lens for an eye, the eye having a pupil, a cornea, and a retina, the intraocular lens having a prescription, the prescription including:

• a plurality of refractive Zernike coefficients corresponding to aberrations of the eye;
• and
• at least one high-order spherical aberration Zernike coefficient;
• wherein after the intraocular lens is implanted into the eye, a combination of the intraocular lens and the eye results in an altered eye, and the altered eye has a presbyopia-mitigating quantity of high-order negative spherical aberration.

A system for defining a prescription of an intraocular lens for an eye, the eye having a pupil, a cornea, and a retina, the system comprising:

• a prescription generator module comprising a processor and a tangible non-transitory computer readable medium, the computer readable medium programmed with a computer application that, when executed by the processor, causes the processor to:
• receive a plurality of refractive Zernike coefficients corresponding to aberrations of the eye;
• and
• define the prescription of the intraocular lens by combining the plurality of refractive Zernike coefficients with at least one high-order spherical aberration Zernike coefficient;
• and
• an output coupled to the prescription generator module and configured to output the prescription of the intraocular lens to be used by a lens-producing assembly;
• wherein after the intraocular lens is implanted into the eye, a combination of the intraocular lens and the eye results in an altered eye, and the altered eye has a presbyopia-mitigating quantity of high-order negative spherical aberration.
