Purpose: 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.
Methods: We 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.
Results: The 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.
Conclusions: Both 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.
