Abstract: An ophthalmic method for determining relationships for calculating intraocular lens (IOL) power correction values is disclosed. The method may involve obtaining estimates of the postoperative optical power of a plurality of eyes undergoing IOL implant surgery. Measurements of the postoperative optical power and of one or more characteristics (e.g., axial length) of the eyes can also be obtained.

For each of the groups, a mathematical relationship can be determined for calculating IOL power correction values based on the measured characteristics. The mathematical relationship can reduce prediction error for the respective eyes in each group when applied to the corresponding estimates of the postoperative optical power. Methods and systems are also disclosed for using the IOL power correction values.
