Purpose
To evaluate patients’ satisfaction and visual outcomes after bilateral implantation of Fusion system compared to bilateral implantation of a trifocal IOL.
Setting
Ophthalmology Clinic, Department of Neurosciences, Biomedicine and Movement Sciences, University of Verona, Verona, Italy
Methods
This randomized single blind clinical trial included 36 patients without ocular comorbidities other than cataract who underwent cataract surgery. Eighteen patients received bilateral Fusion system IOLs (Miniwell in the dominant eye and Miniwell Proxa in the non dominant eye) while the other 18 patients were implanted bilaterally with a trifocal IOL. Threemonth follow-up included: distance corrected and uncorrected visual acuity at 4m (DCVA and UDVA), 80cm (DCI80VA and UI80VA), and 40cm (DCNVA and UNVA), binocular defocus curves, contrast sensitivity (CS), objective (Root mean square-RMS, point- spread-function -PSF- Strehl ratio) visual quality, halometry and the NEI RQL 42 questionnaire was administered.
Results
In the EDOF group binocular UDVA, UI80VA and UNVA were -0.03±0.08, -0.02±0.08, and -0.01±0.09 logMAR, respectively. The values obtained in the trifocal group were -0.05±0.09, 0.06±0.07, and -0.01±0.08 logMAR. EDOF group performed better in the intermediate distances, with a significative statistical difference in both the dominant and non-dominant eyes (P=0,01 and P=0,03 respectively). PSF Strehl ratio was higher in the EDOF group (0.44±0.32) compared to the Trifocal group (0.31±0.19) with statistical significance (p=0,03). Halometric values were significantly better in the EDOF group (P<0,05).
Subjectively, the patients were more satisfied of their far and near vision and experienced less photic phenomena in the EDOF group.
Conclusions
In this study both groups achieved very good visual acuities at all distances, with the EDOF group performing better in the intermediate distances, with a significative statistical difference in both the dominant and non-dominant eyes, the trifocal group at the far distance but without any significative statistical difference. The EDOF group experienced the highest grade of satisfaction after three months experiencing less halo and subjective photic phenomena.
