Patent ID: 8647383

Claim:
An intraocular lens for use in an eye having an optical axis and a spherical aberration of the cornea, the intraocular lens comprising: an optical axis; a reference power distribution region defining a power distribution that is equal to a reference power distribution that is set to cancel the spherical aberration of the cornea when the intraocular lens is inserted into the eye; a positive power deviation region, defining a power distribution that is greater than the reference power distribution, that is radially inward of the reference power distribution region, substantially circular, non-annular, and centered relative to the optical axis, wherein the power of the positive power deviation region is greater than reference power at the optical axis; and a negative power deviation region, defining a power distribution that is less than the reference power distribution, that is radially inward of the reference power distribution region, is substantially annular and centered relative to the optical axis.
