System of determining the correct implantable collamer lens size from ultrasound images of the eye

A method for operating a data processing system to provide an estimate of a vault value for an implantable collamer lens (ICL) to be inserted in a patient's eye, comprising:

• capturing high-frequency ultrasound images of the patient's eye using an ultrasound imaging device, including measuring a diameter of a plane passing through the ciliary body (CBID);
• extracting anatomical measurements from the high-frequency ultrasound images including the diameter of the plane passing through the ciliary body (CBID);
• receiving parameters specifying a power and a size for the ICL based on the anatomical measurements;
• utilizing a calibrated model of a human eye which has been trained on a data set derived from measuring a plurality of different patients before and after ICL implant, to compute an estimated vault value based on the anatomical measurements and the parameters specifying the power and the size for the ICL;
• displaying said estimated vault value to a user of said data processing system;
• and
• implanting said ICL in said patient's eye when said estimated vault value is within a predetermined desired range;
• and
• receiving a parameter specifying a different size for said IC when said estimated vault value is not within said desired range.
