Presbyopia in a patient's eye is treated by inducing spherical aberration in the central section of the pupil, while the peripheral section of the pupil is treated in a manner other than the central section of the pupil. For example, the peripheral section of the pupil may remain untreated, or high-order aberration may be controlled, and/or a second area of spherical aberration may be provided with different focus power. |
