To compare visual outcomes in patients with cataract surgery and bilateral implantation of a trifocal or bifocal intraocular lens (IOL).p>

Setting

<p id="abspara0015">University Eye Clinic Maastricht, the Netherlands.p>

Design

<p id="abspara0020">Prospective randomized clinical trial.p>

Methods

<p id="abspara0025">Eyes with cataract and less than 1.0 diopter (D) of corneal astigmatism were randomized to receive bilateral implantation of Finevision Micro F trifocal IOLs or Acrysof IQ Restor +3.0 bifocal IOLs. Outcome measures were monocular and binocular uncorrected distance (UDVA), uncorrected intermediate (UIVA), and uncorrected near (UNVA) visual acuities; refractive outcomes; binocular defocus curve; contrast sensitivity; reading speed; patient satisfaction; and spectacle independence.p>

Results

<p id="abspara0030">Six months postoperatively, the mean binocular UDVA, UIVA, and UNVA in 56 eyes of 28 patients were 0.01 logMAR &plusmn; 0.11 (SD), 0.32 &plusmn; 0.15 logMAR, and 0.15 &plusmn; 0.13 logMAR in the trifocal group (n = 15) and 0.00 &plusmn; 0.09 logMAR, 0.28 &plusmn; 0.08 logMAR, and 0.12 &plusmn; 0.08 logMAR in the bifocal group (n = 13), respectively. The trifocal group showed a more continuous defocus curve and better results at &minus;1.0 D of defocus (m>Pm> < .01). The mean mesopic contrast sensitivity was higher in the bifocal group (m>Pm> = .02). Complete spectacle independence was reported by 80% of trifocal patients and 50% of bifocal patients. There were no significant differences in refractive outcomes, reading speed, or patient satisfaction.p>

Conclusion

<p id="abspara0035">This study showed noninferiority of visual outcomes with the trifocal IOL compared with the bifocal IOL, although the defocus curve was better at an intermediate distance with the trifocal IOL.p>
