Abstract Details


compare the refractive outcomes between the femtosecond laser-assisted cataract surgery and conventional cataract surgery calculated by 3 third-generation formulas (the Hoffer Q formula, Holladay 1 formula, and SRK-T formula) and 1 fourth-generation formula (the Haigis formula).


Seoul St. Mary hospital, Seoul, Republic of Korea.


This prospective study included 65 eyes from 65 patients who underwent femtosecond laser-assisted cataract surgery and 93 eyes from 93 patients who underwent conventional cataract surgery between November 2013 and July 2014. We compared refractive outcomes between 2 groups using third generation formulas(HofferQ and Holladay1) and a fourth generation formula (Haigis). Preoperative biometry was measured by the IOLMaster (version5,Carl-Zeiss, Germany).Statistical analysis was performed using SPSS statistical software (version 19.0, SPSS, Inc., USA). To determine the significance of the ME and MAE between the 2 groups, Mann-Whitney test was performed, and the total experimental level of significance was set at 0.01.


The absolute values of mean errors were lesser than 0.5 diopter (-0.03 ~ 0.03). The standard deviations of MEs were 0.34 ~ 0.37 diopter in femtosecond laser-assisted group and lesser than the standard deviations of MEs in conventional group (0.46 ~ 0.50 diopter). The mean absolute errors ranged from 0.26 to 0.29 diopter in femtosecond laser-assisted group while MAEs of conventional groups ranged from 0.36 to 0.38 diopter. In analysis of each formula, the difference between 2 groups were 0.07 ~ 0.11 diopter and there were statistically significant differences in the Haigis, Holladay 1, and SRK/T formulas.


The femtosecond laser-assisted cataract surgery showed better refractive outcomes than conventional cataract surgery. The femtosecond laser cataract surgery is expected to be promising technology for future cataract surgery.
