Prospective Comparison of Clinical Outcomes After Bilateral Implantation of Diffractive Trifocal Extended...

To compare clinical outcomes for patients implanted with either FineVision HP or FineVision Triumf intraocular lenses (IOL) (Beaver-Visitec International, Inc) following cataract surgery.

Twenty-six patients bilaterally implanted with the HP IOL and 27 patients with the Triumf IOL were followed up for 6 months in a prospective randomized study. Refraction, uncorrected and corrected distance visual acuity (CDVA), uncorrected and distance-corrected intermediate visual acuity (DCIVA), and uncorrected and distance-corrected near visual acuity (DCNVA) were evaluated. Defocus curves and contrast sensitivity were also measured. Patient-reported outcomes were assessed using the National Eye Institute Visual Function Questionnaire 25, and adverse events were registered.

Ninety-four percent of the eyes in both groups were within ±1.00 diopter (D) of spherical equivalent. All of the patients had 20/20 or better binocular CDVA in both groups and 96% and 100% had 20/25 or better binocular CDIVA in the Triumf and HP IOL groups, respectively, being reduced to 32% and 91.7% for DCNVA, respectively. Differences between groups were statistically significant from -2.00 to -4.50 D with better visual acuity outcomes for the HP IOL group (P < .01). Better monocular photopic contrast sensitivity was found for the Triumf IOL group at 12 and 18 cycles per degree (P < .01). There was a statistically significant increase of the overall composite score in both groups before and after surgery (P < .001). Spectacle independence was similar between groups for distance and intermediate vision but higher for the HP IOL for near vision (96% versus 75%). There were no adverse events related to the IOLs.

Both IOLs showed good and comparable distance and intermediate visual acuities but near vision was better for the HP IOL. This model provided higher spectacle independence for near vision. [.
