Purpose. To report visual outcomes and patient satisfaction after unilateral or bilateral refractive lens exchange (RLE) with a singlepiece\nbifocal diffractive multifocal intraocular lens (MIOL). Methods. All patients underwent RLE with the ZMB00MIOL (Abbott\nMedicalOptics). Patient chartswere reviewed to evaluate the distance, intermediate, and near visual acuity (VA), contrast sensitivity,\nextent of visual symptoms (0ââ?¬â??5), satisfaction (1ââ?¬â??5), and rate of spectacle independence between unilateral and bilateral RLE group.\nResults. Forty-seven eyes of 28 patients were included. No intraoperative complications developed. Mean monocular uncorrected\nVAat distance, intermediate (67 cm), and near (30 cm)were 0.01Ã?±0.12 (standard deviation), 0.27Ã?±0.18, and0.15Ã?±0.11, respectively.\nNo eyes lost >1 line of corrected distanceVA.Monocular contrast sensitivity remained at normal level.Median scores of halos, night\nglare, and starbursts for 27 patientswere 2.0, 3.0, and 0.0, respectively.Median score of satisfaction was 4.0. Therewere no differences\nin visual symptom scores or satisfaction between unilateral and bilateral group (???? > 0.05). Eighty percent of 25 patients reported\ntotal spectacle freedom, with similar rate between bilateral (82%) and unilateral group (75%) (???? = 1.000). Conclusions. RLE with\nthe bifocal diffractive MIOL was safe in presbyopic patients and resulted in a high rate of spectacle independence.
