Comparision of a Novel Trifocal Intraocular Lens and a Monofocal Enhanced Depth of Focus Intraocular Lens in Visual Performance and Quality of Life Scores

Abstract

Abstract Background The aim of this study was to investigate the effects of trifocal and monofocal intraocular lens with enhanced depth of focus implantations Methods 40 patients who had bilateral implantation of the trifocal or monofocal extended depth of focus intaocular lenses after phacoemulsification were included in the study. The preoperative and postoperative examination findings were analyzed. At the 6th postoperative month, binocular defocus curves, contrast sensitivity measurements, subjective complaints, spectacles independence, and the quality of life questionnaire results of the VF-14 questionnaire were also examined. Results While distance and intermediate visual acuities were similar at 6 months postoperatively, near visual acuities were found to be statistically significantly better in the trifocal group. The contrast sensitivity values were found to be statistically better in the edof group. In the trifocal group, 25% of the patients had low-intensity and 5% of the patients had moderate intensity of photopic complaints respectively, while 10% of the patients in the edof group had low-intensity photopic complaints. While spectacles independence could be achieved in all patients in the trifocal group, in the edof group, 80% of patients needed spectacles. When examining VF-14 test values without spectacles, it was found that the values of the trifocal group were significantly higher. Conclusions Trifocal group performed better at near, although far and intermediate vision was comparable between the groups. On the other hand, a higher rate of photic phenomena was observed in the trifocal group. Trial registration: Retrospectively registered
