ABSTRACT
AIM: To explore the effects of femtosecond laser-assisted cataract surgery combined with intraocular lens implantation(FLACS-IOL)on postoperative deviation rate of multifocal intraocular lens(MIOL)and visual quality in cataract patients.METHODS: In the prospective study, 95 patients with cataract(108 eyes)who underwent MIOL implantation in the hospital between January 2021 and December 2022 were enrolled. According to different surgical methods, they were divided into FLACS group(51 cases, 56 eyes)and Phaco group(44 cases, 52 eyes). The operation time, incision diameter of anterior capsule, effective phaco time(EPT), cumulative dissipated energy(CDE), uncorrected distance visual acuity(UCDVA), best corrected distance visual acuity(BCDVA), eccentricity distance of IOL and deviation rate at 3 mo after surgery, total high order aberration(HOA), Trefoil and coma under 3 mm pupil were compared between the two groups.RESULTS: The operation time in the FLACS group was significantly shorter than that in the Phaco group, EPT and CDE were significantly lower than those in the Phaco group(all P<0.05). There was no significant difference in incision diameter of anterior capsule between the two groups(P>0.05). At 1 wk, 3 mo after surgery, UCDVA in the FLACS group was better than that in the Phaco group(all P<0.05). There were significant difference in UCDVA at 1 wk, 3 mo after surgery or BCDVA at 3 mo after surgery between the two groups(P<0.05). At 3 mo after surgery, eccentricity distance of IOL in the FLACS group was shorter than that in the Phaco group, and deviation rate was significantly lower than that in the Phaco group(all P<0.05). Under pupil diameter of 3 mm, HOA, trefoil and coma of whole eyes were decreased in both groups at 3 mo after surgery(P<0.05). At 3 mo after surgery, there were significant differences in HOA and trefoil of whole eyes between the FLACS group and Phaco group(P<0.05), but there was no significant difference in coma at 3 mo after surgery(P>0.05).CONCLUSION: FLACS-IOL can effectively reduce deviation rate of IOL and obtain better visual quality in cataract patients.
ABSTRACT
Objective To assess the reliability and validity of the Chinese version of Multidimensional fatigue symptom inventory-short form(MFSI-SF).Methods The reliability and validity of the Chinese version MFSI-SF were assessed in a sample of 203 cancer patients.Statistical software was used to perform the analysis.Results The results showed moderate correlation between items and the total scale,the content validity index was 0.82,and exploratory factor analysis indicated five dimensions of the scale,the cumulative variance contribution was 56.65％.Confirmatory factor analysis showed moderate model fitting:x2/df=l.73,GFI=0.83,AGFI=0.79,NNFI=0.94,RMSEA=0.06,criterion validity was 0.585,and the Cronbach α of the total scale was 0.896.Conclusions The results demonstrated good convergent validity,it is suitable to evaluate fatigue status in Chinese cancer patients.
