To compare the clinical outcomes between refractive-type multifocal intraocular lenses (IOL) (Lentis Mplus® LS 313, Oculentis GmbH., Berlin, Germany) and diffractive-type multifocal IOL (Acrysof Restor®; SN6AD1, Alcon Lab., Fort Worth, TX, USA) with same near added.
MethodsWe evaluated 30 eyes implanted with Lentis Mplus® IOL and 33 eyes implanted with Acrysof Restor® IOL after phacoemulsification. The distant, intermediate, and near uncorrected visual acuities of the 2 groups were evaluated at 2 weeks and 1, 3, and 6 months postoperatively. Optical quality obtained using the Optical Quality Analysis System II (OQAS II®, Visiometrics, Castelldefels, Barcelona, Spain), higher-order aberrations (HOAs), and patient satisfaction questionnaire of the 2 groups were evaluated at 3 months postoperatively.
ResultsThe visual acuity of intermediate 100 cm was statistically better in the Lentis Mplus® group ( p < 0.05). There were no significant differences between the 2 groups with distant, intermediate 63 cm, and near vision. At the 3-month postoperative follow-up, objective scatter index, modulation transfer function (MTF) cutoff value, and pseudo-accommodation range measured by OQAS II® showed no differences between the 2 groups, but Strhel ratio was higher in the Acrysof Restor® group. HOAs of 5 mm and 6 mm increased significantly in the Lentis Mplus® group. No significant differences were found in the patient satisfaction questionnaire.
ConclusionsBoth refractive and diffractive-type multifocal IOL implantation in patients with cataracts and presbyopia offered good and comparable visual acuity at distance and near. However, the Lentis Mplus® IOL provided better intermediate vision than the Acrysof Restor® IOL.
