M-plus 다초점 인공수정체의 임상성적

Purpose: To evaluate the clinical outcomes of eyes implanted with a zonal refractive multifocal intraocular lens (IOL) with an inferiorsegmental 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 implantedwith AT LISA. The clinical outcomes of these 2 intraocular lenses were evaluated at 1 day and 2 months postoperatively, andconsisted of distant, intermediate, and near visual acuity, contrast sensitivity, degree of tilt, and decentration using anterior segmentphotography, 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 intermediatevisual acuity. In the defocus curve, the M-plus group also demonstrated significantly better visual acuities for intermediateunfocused vision levels. Conclusions: The M-plus multifocal IOLs are able to provide satisfactory distant and near visual acuity and visual function. TheM-plus multifocal IOLs provide better intermediate vision than the AT LISA.
