Abstract:
1. A method for determining an intraocular lens (IOL) power for a patient having a refractively modified cornea, the method comprising: receiving an initial IOL power value determined using the SRK/T formula; receiving a central pachymetry (CP) measurement and a superior corneal pachymetry (SCP) measurement for a cornea of the patient; determining an estimated laser ablation depth by equating a first value to a second value, wherein the first value is a ratio of the sum of the CP measurement and the estimated laser ablation depth to the SCP measurement, and wherein the second value is related to a mean value of a sample of ratios of CP measurements to SCP measurements for a plurality of corneas that have not been refractively modified; determining an IOL power adjustment value using the estimated laser ablation depth; and adding the IOL power adjustment value to the initial IOL power to obtain a corrected IOL power value.
