摘要
Systems and methods for using a new corneal ratio, referred to as the Geggel ratio, to estimate how much treatment a patient received at an original myopic or mixed astigmatism excimer laser refractive surgery. The Geggel ratio represents the ratio of the measure of a pre-IOL central pachymetry to a measure of a pre-IOL superior pachymetry. The estimated laser ablation depth (ELAD) is used in a derived linear regression equation to determine an IOL power adjustment that is added to the standard SRK/T formula used to determine IOL power.
