Purpose:
To assess binocular visual results in patients who were scheduled to undergo cataract/refractive lens exchange with multifocal IOL implantation using a "mix & match" approach.
Methods:
This prospective study enrolled 40 eyes of 20 patients aged between 44 and 78 years (median age = 58.1 years) implanted with a refractive multifocal IOL (ReZoom) in their dominant eye and a diffractive multifocal IOL (Tecnis) in their non-dominant eye. Near, intermediate, and distance vision were assessed at 2 months following implantation. Patients underwent refractive lens exchange or cataract surgery in the dominant eye first, followed by the non-dominant eye 1 to 2 weeks later. Emmetropia was the goal for all surgeries.
Results:
Preoperatively, the mean spherical equivalent refraction was +2.019 +/- 1.417 diopters (D) (median: +2.063 D). The mean binocular distance decimal visual acuity was 1.06 +/- 0.60 D, the mean binocular intermediate decimal visual acuity was 0.50 +/- 0.90 D, and the mean binocular near decimal visual acuity was 1.10 +/- 0.40 D.
Conclusions:
Preliminary visual outcomes in this series of patients indicate good results at all distances.
