Mini-monovision versus multifocal intraocular lens implantation.

PURPOSE: To compare the effect of monovision correction and multifocal intraocular lens (IOL) implantation on patient satisfaction, spectacle dependence, visual acuity, and dysphotopsia in cataract patients.

SETTING

University Hospital of Alexandroupolis, Democritus University of Thrace, Alexandroupolis, Greece.

DESIGN

Prospective randomized trial.

METHODS

Patients with a diagnosis of senile cataract with stage 2 nuclear opalescence were randomly assigned to 2 groups: monovision and multifocal IOL implantation. Uncorrected (UDVA) and corrected (CDVA) distance visual acuity, Visual Function Index-14 (VF-14) scores, and spectacle dependence were assessed prior to surgery and 6 months postoperatively.

RESULTS

The monovision group comprised 38 patients and the multifocal IOL implantation group, 37 patients. Both techniques provided excellent refractive outcomes in UDVA and VF-14 scores (all P < .01). No significant intergroup differences were detected in VF-14 scores at the final postoperative examination. The monovision group patients presented significantly more spectacle dependence for near vision but less glare.

CONCLUSIONS

Monovision and multifocal IOL implantation provided excellent refractive outcomes for distance vision. Multifocal IOL insertion was associated with less dependence on glasses overall but significantly more dysphotopsia.
