Abstract Details


To evaluate the clinical outcomes following implantation of an extended range of vision intraocular lenses (IOLs), TECNIS Symfony® ZXR00, and diffractive multifocal IOLs with +2.75 diopters (D) add power, TECNIS® ZKB00.


Department of Ophthalmology, Korea University College of Medicine, Seoul, South Korea


Sixty eyes of 30 patients who had bilateral implantation of ZXR00 IOL, with intended emmetropia (ZXR00 emmetropia group: 20 eyes) and intended micromonovision (ZXR00 monovision group: 20 eyes), or bilateral implantation of ZKB00 IOL with intended emmetropia (ZKB00 group: 20 eyes). Visual acuity at 4 m, 80 cm, and 40 cm, the incidence of photic phenomena (glare, starbursts, and halos), and types of halos (misty, fine, and rainbow) were analyzed at postoperative 1 and 3 months.


There were no significant differences in distance visual acuity among three groups. The mean uncorrected intermediate visual acuity was better in the ZXR00 emmetropia and monovision groups (respectively, 0.02 logMAR and 0.02 logMAR) than in the ZKB00 group (0.14 logMAR). The mean uncorrected near visual acuity was worse in the ZXR00 emmetropia group (0.26 logMAR) than in the ZXR00 monovision and ZKB00 groups (respectively, 0.12 logMAR and 0.10 logMAR). Although there were no differences in the incidence of photic phenomena, there was a tendency for increasing incidence of rainbow halos in the ZKB00 group than in the ZXR00 groups.


Implantation of the ZXR00 IOLs with intended micromonovision provided superior visual acuity than that of the ZXR00 or ZKB00 IOLs with intended emmetropia. The ZXR00 IOLs tended to show lower incidence of rainbow halos than the ZKB00 IOLs.
