Abstract
Purpose :
To evaluate the clinical outcomes following implantation of an extended range of vision intraocular lenses (IOLs), TECNIS® Symfony, and diffractive multifocal IOLs with +2.75 diopters add power, TECNIS® ZKB00.
Methods :
Sixty eyes of 30 patients who had bilateral implantation of the extended range of vision IOL, with intended emmetropia (non-monovision group: 20 eyes) and intended micromonovision (monovision group: 20 eyes), or bilateral implantation of implantation of diffractive multifocal IOL with intended emmetropia (diffractive IOL group: 20 eyes). Visual acuity, the incidence of photic phenomena (glare, starbursts, and halos), and types of halos (misty, fine, and rainbow) were analyzed at postoperative 1 month.
Results :
There were no significant differences in distance uncorrected, distance corrected, and intermediate uncorrected visual acuity between the non-monovision (0.01, -0.06, 0.02 logMAR) and monovision groups (0.01, -0.04, 0.02 logMAR). On the other hand, uncorrected near visual acuity was significantly better in the monovision group (0.12 logMAR) than in the non-monovision group (0.26 logMAR) (P = 0.008). There were no significant differences in the incidence of photic phenomena among three groups. In the comparison of types of halos, none of the subjects complained of misty halos and there was a tendency for increasing incidence of rainbow halos in the diffractive IOL group than in the monovision and non-monovision groups (P = 0.033).
Conclusions :
Implantation of the extended range of vision IOLs with intended micromonovision provided superior near visual acuity without deteriorating visual symptoms than that with intended monovision. The extended range of vision IOLs tended to show lower incidence of rainbow halos than the diffractive multifocal IOLs.
