Abstract

Abstract : Purpose . This study retrospectively analyzed the postoperative visual functions of myopic eyes implanted with multifocal 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: 26 mm or above (A L ≥ 26 group) and below 26 mm (AL < 26 group). Postoperative corrected and uncorrected distance (5 m) and near (30 cm) visual acuity (VA), contrast sensitivity, and depth of focus were compared between two groups. Results . In theAL ≥ 26 group and theAL < 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 (p = 0.558 and 0.101; Mann-WhitneyU test). For near VA, the corresponding uncorrected VA was0.06 ± 0.08 and0.05 ± 0.09 ; and distance-corrected VA was0.01 ± 0.06 and0.01 ± 0.02, with no significant differences between two groups (p = 0.572, and 0.157; Mann-WhitneyU test). Conclusion . The present study demonstrates that it is possible to achieve good uncorrected near and distance VA following implantation of multifocal IOL in eyes with long axial lengths.
