摘　　要：AIM:To investigate and compare the quality of life,satisfaction,contrast sensitivity,glare,depth perception,and intraocular lens(IOL)rotation in patients who underwent trifocal toric and bifocal toric IOLs.METHODS:A total of 80 eyes of 40 patients were included in this prospective study.Twenty patients in each group were implanted with trifocal toric and bifocal toric IOL,respectively.Preoperative and postoperative 6-month measurements were recorded for both patient groups.Comprehensive anterior and posterior segment examinations,distance-intermediate-near visual acuity values and the visual function scale questionnaire results were evaluated at these examinations.Patient satisfaction,contrast sensitivity,glare,intermediate-near and distance stereopsis and IOL rotation were also evaluated.RESULTS:No significant difference was found between the groups in terms of distance and near visual acuities(P=0.269,P=0.451).Intermediate visual acuity was significantly increased in the trifocal toric group(P<0.001).The visual function scale results were increased after surgery in both groups(P=0.001 and P<0.001),with no difference determined between them(P=0.158 and P=0.691).The number of patients wearing glasses was low in both groups and there was no significant difference between the groups(P>0.05).The overall satisfaction in the trifocal toric group was significantly higher than in the bifocal toric group(P=0.03).The highest sensitivity was observed at 6 cpd spatial frequency in all patients under photopic conditions(1.80±0.24 logU,1.74±0.20 logU).Distance-intermediate-near binocular depth perception results in both groups were higher in the trifocal toric group(P=0.02,0.048,0.003,respectively).Although there was no significant difference for 3 meters stereopsis,the trifocal toric group had higher depth perception(P=0.577).Mean rotation was 5.76°±3.93°in the trifocal toric group and 12°±7.1°in the bifocal toric group.CONCLUSION:Better results in the middle distance are obtained in the trifocal toric group and less
