Visual outcomes and contrast sensitivity after bilateral implantation of multifocal intraocular lenses with +2.50 or +3.0 diopter addition: 12-month follow-up

PURPOSE: To evaluate visual acuity and contrast sensitivity after bilateral implantation of AcrySof® IQ ReSTOR® +2.50 D or +3.00 D. METHODS: A total of 56 eyes with cataract had bilateral implantation of a multifocal IOL. Inclusion criteria were corneal astigmatism less than 1.0 diopters, axial length between 22.0 and 24.0 mm, and no associated ocular disease. Outcome measures recorded 12 months postoperatively were binocular uncorrected and corrected distance, intermediate and near visual acuities, and contrast sensitivity. Postoperative quality of life and patient satisfaction were assessed with the VF-14 Questionnaire. RESULTS: Twenty months postoperatively, the mean uncorrected and best-corrected distance visual acuities, UCIVA at 60 cm, and contrast sensitivity were similar in all two groups. UCNVA were better in the +3.00 IOL group than in the +2.50 D group. Patients reported good performance for visual tasks. CONCLUSION: Apodized multifocal IOLs seem a good compromise for non-spectacles life in elderly patients; our study indicates that this solution has a good long-term stability on patients' visual function.
