Objective To study the visual quality of femtosecond laser-assisted cataract surgery and conventional phacoemulsification in patients with cataract.Methods In this case-control study,a total of 83 patients were randomly divided into study group (52 eyes) and control group (48 eyes).Postoperative 1 day,1 week,1 month measured 2 groups of patients the best corrected visual acuity (BCVA),iTrace visual function analyzer is used to measure the two naturally take group a high order aberration of the pupil diameter is 3 mm (total eye High order aberration,Spherical,coma,trefoil) and total higher-order aberration of the modulation transfer function (MTF).Data using the single factor analysis of variance.Results Two groups of BCVA 1 d after surgery,there were differences in postoperative 1 week, there was statistical significance,no obvious difference was found between postoperative BCVA of 1 month, no statistical significance.After 1 day,1 week,1 month experimental eyes naturally made full eye pupil diameter of 3 mm total eye High order aberration,Spherical,coma,trefoil was better than that of control group,with statistical significance,high-order aberration of MTF was better than that of control group,with statistical significance.After 1 day,1 week,1 month, all experimental surgery eye the mean total higher-order aberrations was lower than the control group,both groups showed a trend of decline over time,and both the mean gradually close to change over time.Postoperative 1 day,1 week,1 month experimental technique under the eye always higher-order aberrations of MTF average higher than that of control group,both groups showed a trend of increasing over time, and the average change over time approaching.Conclusion The femtosecond laser-assisted cataract surgery compared with the conventional phacoemulsification cataract surgery has better visual quality. The femtosecond laser-assisted cataract surgery has a great clinical effects which improve patients visual quality early.
