Abstract
Certain exemplary embodiments include methods of determining ophthalmic prescriptions to ameliorate presbyopia. Certain exemplary embodiments provide an ophthalmic lens having spherical aberration of the same sign as the patient's eye and of a magnitude effective to substantially provide a desired net spherical aberration for an optical system including the patient's eye and the ophthalmic lens where the desired net spherical aberration provides a desired increase in near vision. Certain exemplary embodiments include contact lenses, intraocular lenses, corneal onlays, corneal inlays, or corneal surgeries providing spherical aberration of the same sign as the patient's eye and of a magnitude effective to substantially provide a desired net spherical aberration for an optical system including the patient's eye and the ophthalmic lens where the desired net spherical aberration provides a desired increase in near distance vision.
