Abstract
PURPOSE
To evaluate the clinical outcomes of eyes implanted with a zonal refractive multifocal intraocular lens (IOL) with an inferior segmental near add (M-plus), and to compare the outcomes between M-plus and a diffractive-type multifocal IOL, AT LISA (366D, bifocal). METHODS: We reviewed 19 eyes from 10 patients who were implanted with M-plus and 52 eyes of 26 patients who were implanted with AT LISA. The clinical outcomes of these 2 intraocular lenses were evaluated at 1 day and 2 months postoperatively, and consisted of distant, intermediate, and near visual acuity, contrast sensitivity, degree of tilt, and decentration using anterior segment photography, depth of focus, and patient satisfaction. RESULTS: There were no statistical differences between the 2 groups with respect to distant vision, near vision, refractive error, contrast sensitivity, degree of tilt, decentration, or satisfaction score. The M-plus group demonstrated significantly better intermediate visual acuity. In the defocus curve, the M-plus group also demonstrated significantly better visual acuities for intermediate unfocused vision levels. CONCLUSIONS: The M-plus multifocal IOLs are able to provide satisfactory distant and near visual acuity and visual function. The M-plus multifocal IOLs provide better intermediate vision than the AT LISA.
