PURPOSE: To compare visual, refractive, and satisfactory outcomes between a new-generation sectorial addition multifocal intraocular lens (IOL) (Lentis Mplus LS-312; study group) and a diffractive apodized multifocal IOL (Restor SN6AD1; control group). SETTING: Private practice, Driebergen, and Department of Ophthalmology, Academic Medical Center, Amsterdam, The Netherlands. DESIGN: Comparative case series. METHODS: Refractive and visual outcomes at near and distance, patient satisfaction, and dysphotopsia scores were recorded 3, 6, and 12 months postoperatively. RESULTS: The study group comprised 90 eyes and the control group, 143 eyes. Three months postoperatively, the mean uncorrected distance visual acuity (UDVA) was not statistically significantly different between the study group and the control group (0.04 +/- 0.15 logMAR [SD] versus 0.06 +/- 0.25 logMAR). The control group had significantly better uncorrected near visual acuity than the study group at 30 cm (0.05 +/- 0.14 logMAR versus 0.15 +/- 0.08 logMAR) and 40 cm (0.05 +/- 0.14 versus 0.16 +/- 0.21) (P<.01 and P<.03, respectively). Patients in the control group were more satisfied with their vision (P<.001). Dissatisfaction was related to younger age at surgery and male sex (P<.0001 and P<.033 respectively). Dysphotopsia occurred in approximately 18% of cases in both groups. CONCLUSIONS: The new sectorial addition multifocal IOL performed comparably to the diffractive apodized multifocal IOL in terms of UDVA and the presence of dysphotopsia. The diffractive apodized multifocal IOL performed better at 30 cm and 40 cm reading distances and had higher patient satisfaction.
