Clinical outcomes with a trifocal intraocular lens: a multicenter study.
OBJECTIVE
To evaluate the clinical results and safety obtained with a new type of multifocal intraocular lens (IOL) using a trifocal design to achieve pseudoaccommodation.


METHODS
A pilot observational study of patients with a trifocal IOL (FineVision; PhysIOL, Liege, Belgium) implanted by 1 of 12 surgeons between March and December 2010. Visual outcomes that were assessed postoperatively included uncorrected and corrected distance, intermediate, and near visual acuity.


RESULTS
One hundred ninety-eight eyes of 99 patients were analyzed. Patients were observed for an average of 6.44 ± 4.67 months (range: 0.2 to 17 months). Preoperative corrected distance visual acuity was 0.22 ± 0.26 logMAR. At the final follow-up visit, corrected distance visual acuity was 0.01 ± 0.10 logMAR, uncorrected distance visual acuity was 0.01 ± 0.06 logMAR, uncorrected intermediate visual acuity was 0.08 ± 0.10 logMAR, and mean uncorrected near visual acuity was 0.00 ± 0.04 logMAR. Postoperative binocular uncorrected distance visual acuity was 0.01 ± 0.07 logMAR, uncorrected intermediate visual acuity was 0.06 ± 0.08 logMAR, and uncorrected near visual acuity was -0.03 ± 0.04 logMAR. Postopeative mean residual sphere was 0.21 ± 0.48 diopters (D), with a residual cylinder of -0.24 ± 0.31 D. Postoperative spherical equivalent was 0.11 ± 0.36 D.


CONCLUSIONS
The results demonstrated that the trifocal FineVision IOL is able to restore near, intermediate, and distance visual function.
