1. A method for operating a data processing system to provide a vault value for a PIOL, characterized by a front surface and a back surface, to be inserted in a patient's eye between a crystalline lens, characterized by an anterior surface and a posterior surface and an iris, said method comprising:
causing said data processing system to receive a plurality of high-frequency ultrasound-based anatomical measurements of said patient's eye, wherein said plurality of anatomical measurements includes CBID;
causing said data processing system to receive a parameter specifying a power for said PIOL;
causing said data processing system to receive a parameter specifying a size for said PIOL;
[a] computing predicted vault value by using a function of said plurality of anatomical measurements and said parameters specifying said power and said size for said PIOL, wherein said function comprises a*CBID+b*STSL+c*(PIOL Power)+d*(PIOL size)+e*SPD, wherein parameters a, b, c, d, and e are determined by fitting observed vault values in a patient group, said vault value being a separation between said anterior surface of said patient's crystalline lens and said back surface of said PIOL;
[b] implanting said PIOL in said patient's eye if said predicted vault value is within a desired range; and if said predicted vault value is not within said desired range, causing
said data processing system to receive a parameter specifying a different size for said PIOL; and
upon receiving the parameter specifying the different size for said PIOL repeating steps [a]-[b] with said different size.
