Abstract

PURPOSE: To assess the usefulness and reliability of the IOL power calculation computer program ('POWER!').
METHODS
Calculation times and projected postoperative refractive values of 100 patients with 'POWER!' program were compared with those of the program mounted on the Humphrey R A/B scan system (model 820) by SRK-II and SRK/T formula.
RESULTS
There was no significant difference between the projected postoperative refractive values of 'POWER!' program and Humphrey R A/B scan system (paired-t test, p>0.05). Calculation time of 'POWER!' was shorter than that of the program mounted on the Humphrey R A/B scan system incalculating more than 3 sets of IOL (paired-t test, P<0.05) and there was no internal calculation error (ztest, p>0.05).
CONCLUSIONS
'POWER!' is a useful and reliable program for IOL power calculation using SRK-II and SRK/T formula.
