Purpose.This study retrospectively analyzed the postoperative visual functions ofmyopic eyes implantedwithmultifocal intraocular lens (IOL) to evaluate the efficacy of multifocal IOL in highly myopic eyes. Methods. We studied 61 patients (96 eyes) who were implanted with multifocal IOL ZMA00 or ZMB00 (Abbott Medical Optics). The patients were stratified into two groups by axial length: 26mm or above (AL ≥ 26 group) and below 26mm (AL < 26 group). Postoperative corrected and uncorrected distance (5m) and near (30 cm) visual acuity (VA), contrast sensitivity, and depth of focus were compared between two groups. Results. In the AL ≥ 26 group and the AL < 26 group, the mean ± standard deviation uncorrected distance logMAR VA at 12-month postoperative follow-up was −0.04 ± 0.11 and −0.01 ± 0.14, respectively; and the corrected distance VA was −0.17 ± 0.08 and −0.14 ± 0.07, with no significant differences between two groups
