Abstract Details

Purpose:

To compare binocular uncorrected visual acuities (VA) between implantation of extended range of vision intraocular lenses (IOLs) targeting emmetropia and slight myopia (-0.5D).

Setting:

Department of Ophthalmology, Tokyo Dental College Suidobashi Hospital

Methods:

This prospective study included 32 eyes of 16 patients who received extended range of vison IOLs (ZXR00, Johnson&Johnson Vision) bilaterally. According to the patient’s life style, IOL power was selected to achieve postoperative refraction of emmetropia (group E) and slight myopia of -0.5D (group L). Binocular uncorrected logMAR visual acuities (UCVAs) at 5m, 1m, 70cm, 50cm, 40cm, and 30cm, and spectacle usage were assessed 3 months postoperatively.　

Results:

The mean UCVAs of groups E/L were -0.13/-0.10 for 5 m, -0.08/-0.09 for 1 m, -0.04/-0.08 for 70 cm, 0.05/-0.02 for 50 cm, 0.15/0.08 for 40 cm, and 0.31/0.25 for 30 cm. Significantly better VA in group L was found at 50 cm (p=0.039 Mann-Whitney U Test). Two patients (25%) of group E and 5 patients (62.5%) of group L did not require any spectacles.

Conclusions:

Implantation of EDOF IOL targeting -0.5 D would increase the range of better uncorrected vision.
