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.
