Clinical outcomes with a new microincisional diffractive multifocal IOL

Background:To evaluate the refractive outcomes and the optical performance as well as the quality of life in patients implanted with a new diffractive multifocal intraocular lens(IOL).Methods:Prospective,clinical study including 41 cases of patients who underwent cataract surgery and were divided in two groups:group 1,including 20 eyes implanted with the multifocal IOL SeeLens MF(Hanita Lenses,Israel);group 2,21 eyes implanted with the Acrysof SA60AT IOL.Visual acuity,defocus curve,intraocular aberrations,contrast sensitivity function and quality of life were assessed during a follow up period of 6 months.Results:Significant improvement was observed in the uncorrected distance visual acuity(UDVA)and corrected distance visual acuity(CDVA)in both groups(p<0.02).The multifocal group showed better results in terms of uncorrected near visual acuity(UNVA)and distance-corrected near visual acuity(DCNVA)(p<0.01).Comparison of both groups showed better visual acuities for the multifocal IOL group in defocus levels from-3.0 D to-1.50 D(p≤0.01).At 6 months,there was a significant reduction of the internal higher order aberrations(p≤0.04).A significant increase in scotopic contrast sensitivity was detected for 6 cycles/°spatial frequency during follow up(p=0.04),but no significant changes were observed for the rest of spatial frequencies(p≥0.06).Visual Functioning Index(VF-14)questionnaire showed that patients reported high levels of satisfaction when performing daily tasks.Conclusions:The SeeLens MF IOL is able to successfully restore distance,near and intermediate visions after cataract surgery.It also provides functional intermediate vision with optimal intraocular optical quality.
