Comparison of visual and refractive outcomes of 2 trifocal intraocular lenses.

PURPOSE

To compare clinical outcomes after cataract surgery and bilateral implantation of 2 diffractive trifocal toric intraocular lenses (IOLs).

SETTING

Hospital da Luz, Lisbon, Portugal.

DESIGN

Double-arm, randomized, prospective case series.

METHODS

A total of 60 patients were randomly allocated to receive bilateral implantation of either the FineVision Pod FT toric IOL (PhysIOL) or the AcrySof IQ PanOptix toric IOL (Alcon). Visual and refractive outcomes, contrast sensitivity, IOL misalignment, and quality of vision outcomes (QoV questionnaire) were evaluated at 3 months postoperatively. Surgically induced astigmatic changes were evaluated by vector analysis.

RESULTS

Each group (FineVision toric and AcrySof IQ PanOptix toric) comprised 30 patients (60 eyes). No significant differences between groups were found regarding uncorrected and corrected distance and near visual outcomes (P ≥ .333). Mean postoperative distance-corrected intermediate visual acuity at 60 cm was 0.04 ± 0.09 logarithm of the minimum angle of resolution (logMAR) and 0.09 ± 0.11 logMAR in the PanOptix and Pod FT group, respectively (P = .032). Mean IOL axis misalignment was 1.59 degrees ± 2.15 degrees (PanOptix group) and 1.89 degrees ± 3.31 degrees (Pod FT group) (P = .821). Mean magnitude of error of astigmatic correction was -0.09 diopters (D) and -0.11 D in the PanOptix group and Pod FT group, respectively (P = .333). Contrast sensitivity, QoV scores for the presence of photic phenomena, and the level of spectacle independence were similar in both groups (P > .05).

CONCLUSIONS

Both trifocal toric IOLs allowed complete patient visual restoration, and good spectacle independence and good visual quality outcomes. The PanOptix IOL provided superior intermediate visual acuity for distances around 60 cm.
