Abstract:
1. A method of performing visual correction in a patient by implanting an intraocular lens, which at least partially compensates for an aberration of the cornea, comprising: (i) measuring an aberration of the eye by: (ii) modeling an intraocular lens having a spherical surface and an aspheric surface, the spherical surface having a radius, and the aspheric surface having a radius, a conic constant and at least one non-zero aspheric polynomial constant; (iii) selecting a power of the intraocular lens, wherein the radius of the spherical surface and the radius of the aspheric surface determine the power of the intraocular lens; and (iv) selecting a spherical aberration of the intraocular lens to offset the spherical aberration of the cornea, wherein the conic constant and the at least one aspheric polynomial constant of the aspheric surface determine the spherical aberration of the intraocular lens.
