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.
