PURPOSE: Evaluation of the clinical data 3 months after implantation of a new diffractive multifocal intraocular lens (MIOL) with a reduced near add power of + 2.75 D. METHODS: In a prospective study, patients who underwent cataract surgery or refractive lens exchange with implantation of an MIOL (Tecnis ZKB00, Abbott Medical Optics, Santa Ana, California, USA) were included. Three months postoperative corrected and uncorrected visual acuities at different distances were measured and evaluated. Those patients that underwent bilateral MIOL implantation additionally filled out a questionnaire 3 months postoperatively. RESULTS: Between October 2013 and August 2014, 115 eyes of 62 patients were implanted with the ZKB00 IOL. Mean postoperative refractions were - 0.27 ± 0.44 D for the spherical equivalent, respectively. Mean binocular CDVA was - 0.01 ± 0.3 logMAR with a mean binocular UDVA of 0.06 ± 0.08 logMAR. For near distance in 40 cm, an UNVA of 0.07 ± 0.10 logMAR three months postoperatively was measured. CONCLUSION: The ZKB00 IOL belongs to a group of novel MIOL with an increased intermediate visual performance. Our study shows good visual acuity at all distances, as well as a high rate of satisfaction and subjectively good image quality. Georg Thieme Verlag KG Stuttgart · New York.
