Abstract
Objective To compare the tilt,decentration,high order aberrations (HOAs) and modulation transfer function (MTF) of two different one-piece designed aspheric intraocular lens (IOL) after the phacoemulsification and IOL implantation in order to select the better aspheric IOLs.Methods Eighty eyes were received the phacoemulsification and IOL implantation surgery.According to the spherical aberration of comeal,40 eyes were implanted Tecnis ZCB00 IOL,other 40 eyes were implanted ADAPT-AO IOL.The tilt,decentration,high order aberrations (HOAs) and modulation transfer function (MTF) of the two IOLs were measured 1 month and 3 months after the surgery by iTrace and Pentacam at 6mm pupil size.The image-pro plus software was used to measure the values of tilt and decentration of the two IOLs.All the values were analyzed by paired t-test in one group and by independent sample t-test,the tilt and decentration by Pearson regression analysis.Results There was no linear correlation between tilt and decentration of the two IOLs (P ＞0.05).About the values of tilt and decentration,no significant difference was found no matter in one group or between two groups 1 month and 3 month after surgery (P ＞0.05).There was no statistically significance in the high order aberration (HOA),coma and spherical in one group (P ＞0.05),but the differences of the high order aberration (HOA) and spherical between two groups were statistically significant in 1 and 3 months after surgery (P =0.005,0.012,0.000,0.000,0.023,0.041,0.014,0.002),And there was no difference statistically between two groups on the coma (P ＞0.05).The MTF had no significant difference in each group and between two group 1 month and 3 months after surgery (P ＞0.05).Conclusions The two different one-piece designed aspheric IOLs have shown good stability and centration 1 month and 3 months after surgery.ZCB00 is better than AO in visual quality after surgery in some extent,but long-term effects remains to be seen.
