RESUMEN
·AIM: To investigate the effect of femtosecond laser assistedcataractsurgeryconventional phacoemulsification surgery on corneal endothelial cell morphology and function. ·METHODS: This study included 80 cases of cataract patients (88 sicked eyes) treated in our hospital from January 2016 to January 2017. All patients underwent phacoemulsification combining with intraocular lens implantation for treatment. Based on the review of treatment, 40 cases ( 43 sicked eyes ) receiving femtosecond laser assisted cataract surgery were included into the observation group, 40 cases (45 sicked eyes) receiving conventional phacoemulsification only were divided into the control group. The proportion of patients whose postoperative uncorrected visual acuity >0.5 of the two groups were compared, and sac diameter, capsule size, intraoperative cumulative energy release (CDE) were recorded, the corneal endothelial cell density and variation were recorded before and after operation, the preoperative and postoperative ratio of hexagonal cells were compared between the two groups subsequently. and ·RESULTS: At 1d postoperatively, uncorrected visual acuity >0.5 of the observation group was no significant difference with that of the control group; the ratio was 74% at 6mo after surgery, which was significantly higher than that of the control group(53%),there was statistical significance (P < 0. 05). The diameter of the anterior capsulotomy,the size of the capsule,the grade Ⅱ nuclear CDE, and the grade Ⅲ nuclear CDE of the observation group were sharply different from those of the control group, there was statistical significance (P<0.05). The differences of corneal endothelial cell density and variation, proportion of hexagonal cells before and after surgery of the two groups were significant, and the difference after 6mo between the two groups was huge, there was statistical meaning (P<0.05). · CONCLUSION: Femtosecond laser assisted cataract surgery can reduce the effect of ultrasound energy on cornea,and can sharply decrease the damage to corneal endothelial cell morphology and function.
RESUMEN
·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.
