Abstract Details

Purpose:

To compare outcomes between patients implanted bilaterally with a trifocal intraocular lens (IOL) and patients implanted with bifocal IOLs having different near addition in each eye.

Setting:

Hayashi Eye Hospital, Fukuoka, Japan.

Methods:

Seventy-eight patients scheduled for multifocal IOL implantation were divided into a trifocal group (n=32) implanted bilaterally with trifocal IOLs (Alcon TFNT00), and a combined bifocal group (n=46) implanted with a bifocal IOL with +3.0 diopter (D) addition in the dominant eye and +4.0D addition in the non-dominant eye. At 3 months postoperatively, binocular all-distance visual acuity (VA), binocular contrast VA and that with glare (glare VA), near stereoacuity, and incidence of patients reporting halo symptom were assessed.

Results:

Mean binocular uncorrected and corrected VAs at far to intermediate distances were significantly better in the trifocal group than in the combined bifocal group (P≤.0325), while binocular near VA did not differ significantly between groups. Mean photopic and mesopic contrast VA and glare VA at most contrasts, and stereoacuity were significantly better in the trifocal group than in the combined bifocal group (P≤.0426). The incidence of patients reporting moderate halo symptom was significantly greater in the trifocal group (P=.0482).

Conclusions:

Bilateral implantation of a trifocal IOL provided significantly better binocular VA from far to intermediate distances and comparable near VA compared with combined implantation of bifocal IOLs with +3.0D and +4.0D addition. Contrast VA and stereoacuity were significantly better but incidence of halo symptoms tended to be worse in patients with trifocal IOLs.
