ABSTRACT

·AIM: To evaluate the effect of femtosecond laser assisted cataract surgery combined with triple - focus intraocular lens implantation in the treatment of cataract. ·METHODS:Totally 86 cases (106 eyes) of patients with double cataract in our hospital from January 2016 to January 2017 were selected, including 49 cases (59 eyes) were set as the observation group ( treated with femtosecond laser assisted phacoemulsification combined with triple-focus intraocular lens implantation), and 37 cases (47 eyes) were set as the control group (received traditional phacoemulsification combined with triple -focus intraocular lens implantation). Corneal endothelial cell density,cumulative dissipated energy(CDE),distant and near visual accommodation before and after operation were compared between the two groups, postoperative complications were observed. ·RESULTS: The preoperative corneal endothelial cell density of two groups had no significant difference (P>0.05). The corneal endothelial cell density of two groups significantly decreased at postoperative 1wk,with statistic significance within groups (P<0. 05), and the corneal endothelial cell density of the control group was significantly lower than that of the observation group at postoperative 1wk (P<0.05). The CDE of the observation group were lower than that of the control group, and the difference between the two groups was significant (P<0.05). There were significant differences in best corrected visual acuity at different time points between the two groups (P<0.01). The best corrected visual acuity at 1 and 3mo after operation in the observation group was higher than that in the control group, and the difference was significant (P<0.05). There was no capsular tear in the observation group,while the incidence rate was 4.3% in the control group, with no significant difference between the two groups(P>0.05). The incidence of glare and halo in the observation group was 10.2% and 8.5% in the control group,and are in the patients whose age was above 60 years old, there was no significant difference between the two groups (P>0.05). · CONCLUSION: Femtosecond laser assisted cataract surgery combined with triple - focus intraocular lens implantation in the treatment of cataract can not only improve curative effect, but also provide high safety, while the adverse events including glare, halo and other adverse visual circumstances should be considered after triple-focus intraocular lens implantation.
