To compare the postoperative clinical outcomes after cataract surgery and implantation using the BunnyLens MF® and ReSTOR® multifocal intraocular lenses. METHODS: Sixty-five eyes implanted with multifocal intraocular lenses were divided into two groups involving either ReSTOR® (39 eyes) or BunnyLens MF® (26 eyes) lenses. In these two groups, the distant and near visual acuity, astigmatism, spherical equivalent, and contrast sensitivity test were examined at preoperative and postoperative 1 week, 8 weeks, and 24 weeks. We compared the clinical efficacy between the two groups before and after cataract surgery using statistical analysis. RESULTS: The mean value of distant and near visual acuity, and spherical equivalent of both groups after intraocular lens implantation were significantly improved, compared with the preoperative values (p < 0.05), while there was no significant differences between the two groups (p > 0.05). The means of postoperative distant and near visual acuity, astigmatism, and contrast sensitivity test were not significantly different between ReSTOR® and BunnyLens MF® lenses (p > 0.05). The mean numeric error of spherical equivalent at the final postoperative 24 weeks was −0.17 ± 0.50 diopters (D) for the ReSTOR® lenses and −0.34 ± 0.52 D for the BunnyLens MF® lenses (p > 0.05). CONCLUSIONS: BunnyLens MF® and ReSTOR® lenses showed no significant difference in clinical efficacy, including distance and near vision, spherical equivalent error, and contrast sensitivity test after cataract surgery. However, it should be noted that BunnyLens MF® lenses had a tendency toward myopic shift compared with ReSTOR® lenses.
