Purpose

To compare visual outcomes and patient satis faction between unilateral and bilateral trifocal diffractive intraocular lens (IOL) implantation in emmetropic patients with presbyopia.

Setting

Retrospective observational case series.

Methods

A multicenter, multisurgeon study was made in patients emmetropic presbyopes who underwent refractive lens exchange (RLE) followed by an implantation of FineVision IOL (PhysIOL. Inclusion criteria were emmetropic eyes, with a sphere between –0.25 and D0.50 diopters (D), cylinder of less than 0.75 D and spherical equivalent (SE) between –0.25 and D0.25 D. In addition, uncorrected distance visual acuity (UDVA) had to be Snellen >0.9 in each eye. A total of 171 eyes of 122 patients were evaluated. This sample was divided into 2 groups depending on whether they have been operated monocularly or binocularly. Visual and refractive performance, patient satisfaction, and spectacle independence were evaluated.

 

Results

UDVA and corrected distance visual acuity (CDVA) remained almost unchanged after monocular and binocular surgery. Binocular uncorrected intermedi- ate (UIVA) and near visual acuity (UNVA) were better in those operated binocularly (0.3±0.12 vs 0.22±0.06, P < .063, and 0.09±0.08 vs 0.04±0.05, P < .027, respectively). Predictability and efficacy were higher in the binocular group, whereas safety was better in the monocular group. Visual dysphotopsia was worse and spectacle independence for all distances was higher in binocular group.

 

Conclusion

RLE with binocular implantation of a trifocal diffractive IOL in presbyopic emmetropic patients is more successful in UNVA than monocular implantation. No significant differences in UDVA, UIVA, and patient satisfaction were observed.
