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.
