Abstract
Purpose: :
To retrospectively compare the visual outcomes of bilateral TECNIS multifocal (TMF/TMF) to a combination of the TECNIS multifocal and a ReZoom (TMF/RZ).
Methods: :
A retrospective analysis of distance, intermediate, and near visual outcomes of TMF/TMF (n=60) versus TMF/RZ (n=72) was performed. Questionnaires were administered to evaluate patient satisfaction and spectacle independence.
Results: :
264 eyes (132 pts) having received TMF/TMF (n=60) or TMF/RZ (n=72) achieved near uncorrected visual acuities of 20/25 and 20/26 respectively. Mean BCVA were 20/22 in each group. Mean post op residual astigmatism was 0.41D for TMF/TMF and 0.49D for TMF/RZ. The mean sph. eq. of TMF/TMF was +0.06D and was -0.07D for TMF/RZ. The mean unilateral uncorrected near vision was J1.19 for MF/TMF and J1.47 for TMF/RZ. The mean bilateral uncorrected near vision was J1.00 for TMF/TMF and J1.16 for TMF/RZ. The mean unilateral uncorrected intermediate vision was J3.32 for TMF/TMF and J3.15 for TMF/RZ. The bilateral intermediate vision was J2.77 for TMF/TMF and J2.21 for TMF/RZ. Reports of unwanted light phenomenon while driving at night were greater in the TMF/RZ group, but the differences were not significant. No explantations were performed in either group due to halos or glare. Reports of patient satisfaction were higher for the TMF/TMF group but the differences were not significant.
Conclusions: :
Favorable visual outcomes and high levels of patient satisfactions were achieved in both cohorts. Near vision was favored in the TMF/TMF cohort and intermediate vision was favored in the TMF/RZ cohort, but the differences were not significant. Clinically, the TMF/RZ group reported more halos and glare but statistically the differences were not significant, and no explantations were performed in either cohort.
