To clinically evaluate different near additions (adds) (+3.00 diopters [D] and +4.00 D) of the M-flex 630F refractive multifocal intraocular lens (IOL).Departments of Ophthalmology, University of Heidelberg, Germany, and Lithuanian University of Health Sciences, Kaunas, Lithuania.Clinical prospective nonrandomized unmasked study.Preoperatively, cataract patients were assigned to receive bilateral +3.00 D IOLs, +4.00 D IOLs, or +3.00 D (dominant eye) and +4.00 D (nondominant eye) IOLs. Follow-up examinations were performed up to 6 months postoperatively and included refraction, visual acuity (near at 40 cm and distance), the defocus curve, contrast sensitivity, and a subjective questionnaire.Fifty-two patients were enrolled. No significant differences were found in the visual acuity results (P>.05). Four to 6 months postoperatively, the following median uncorrected and corrected distance visual acuity, uncorrected and distance-corrected near visual acuity, and corrected near visual acuity (logMAR) were found in all patients: -0.08, -0.12, 0.20, 0.10, and 0.10. Ninety-eight percent of patients reported being satisfied. The highest near peak versus the biggest intermediate decline in the median monocular defocus curves comparing +3.00 D and +4.00 D multifocal IOLs (logMAR) were 0.16 at 40 cm versus 0.22 at 33 cm (P=.24) and 0.38 at 66 cm versus 0.54 at 50 cm (P<.01).Compared with the +4.00 D add, the +3.00 D near add gave better intermediate results in the defocus curve without compromising distance or near visual acuity.
