Purpose: To compare patient-reported outcomes (PROs) and satisfaction results after multifocal intraocular lens (IOL) implantation in three groups: two receiving bilateral implantation of the same IOL and another undergoing blended vision with two different multifocal IOLs.
Patients and methods: A questionnaire was administered to patients who had undergone uncomplicated cataract surgery and 2 months of follow-up: the first group underwent bilateral implantation with Alcon’s AcrySof ReSTOR 3.0 lens (“3.0/3.0,” n=78); the second group underwent implantation with the ReSTOR ActiveFocus 2.5 or the ReSTOR ActiveFocus 2.5 toric lens (“2.5 mini-monovision,” n=102); and the third group underwent implantation with the ReSTOR 2.5 lens in the dominant eye and the ReSTOR 3.0 lens in the non-dominant eye (“2.5/3.0,” n=89).
Results: Overall PROs and satisfaction was similar among the groups. Refractive outcomes and accuracy were similar among the groups, but the 2.5 mini-monovision group reported better intermediate vision. Refractive outcome differences were not meaningful among the groups and were not a differentiating factor in PROs. Substantially fewer patients in the 2.5 mini-monovision group noticed glare and halo compared with the 3.0/3.0 group (P<0.0001, chi-square test). No new safety concerns were reported.
Conclusion: The 2.5 mini-monovision results in a higher percentage of patients being satisfied with intermediate vision than bilateral ReSTOR 3.0 or blended vision with ReSTOR 2.5/3.0 implants, but overall PRO differences were not statistically significant.
