To evaluate the clinical outcomes with an extended range of vision (ERV) IOL based on achromatic diffractive technology.
This was a prospective comparative study including 60 eyes undergoing cataract surgery with implantation of the ERV Tecnis Symfony IOL (Abbott Medical Optics, Inc.) (ERV group: 60 eyes of 30 patients). Visual, refractive, contrast sensitivity, defocus curve, ocular optical quality (Optical Quality Analysis System; iTrace), and visual function questionair（NEI-VFQ 25） outcomes were evaluated during a 3-month follow-up.

| Questionnaire concerning halo and visual function | NEI-VFQ 25 patient questionnaire score. The questionnaire consisted of 3 parts. The first part assessed patients' satisfaction with their overall vision during the day, or at night. The score ranged from 1 to 5 (1 = not at all; 2 = a little bit; 3 = moderately; 4 = quite a bit; 5 = extremely). In part 2, patients were asked to rate the extent to which they have difficulties with their overall vision during the day or at night. The score ranged from 1 to 5 (1 = none of the time; 2 = some of the time; 3 = half of the time; 4 = most of the time; 5 = all of the time). In part 3, patients were asked to rate their overall vision and their vision at near, intermediate, and distance on a scale ranging from 0 to 10 (0 = worst; 10 = best). |
