Patent ID: 8235525

Claim:
A method for making an intraocular lens capable of adjusting the aberrations of the eye in order to provide optimal vision correction to patients, the method comprising the steps of: providing a mathematical model eye that describes the optical setup and performance of the natural human eye including a visual axis tilted with respect to the axis of symmetry of the eye; and, a decentered iris that represents a decentered entrance pupil; determining the performances of the mathematical model eye with respect to image quality and spherical aberrations as a function of pupil diameter; using a mathematical model describing the statistics of potential lens misalignments and positioning errors induced by surgery or wound healing processes; calculating the optical performance and resulting aberrations employing said mathematical eye model convoluted with the statistical model for lens displacements; and, optically modeling an aspherical lens shape that replaces 20 the natural human crystalline lens in the eye that provides optical power restoration while providing optical characteristics of the human lens in order to cause the eye with the intraocular lens having aspherical shape to have the same amount of spherical aberrations and the same level of image quality than the mathematical model eye as a function of the pupil diameter; and, producing the intraocular lens based on the data acquired by the above method steps.
