Visual Outcomes Following Bilateral lmplantation of Two Diffractive Trifocal IOLs in 10,084 eyes

Abstract Purpose To investigate refractive and visual acuity outcomes, patient satisfaction and spectacle independence at three months of two diffractive (non-toric) trifocal IOLs in a large series of patients. Design Multicenter, retrospective, non-randomized clinical study. Methods Patients underwent lens phacoemulsification and were implanted bilaterally with a diffractive trifocal IOL: FineVision MicroF or AT Lisa tri 839MP. Surgeries were performed between 2011 and 2015 with at least 3 months of follow-up. Visual and refractive performance, patient satisfaction and spectacle independence were evaluated. Results 10,084 trifocal IOLs were bilaterally implanted (5,802 FineVision in 2901 patients and 4,282 AT Lisa in 2141 patients). Three-months mean acuity: AT Lisa, binocular uncorrected distance visual acuity (UDVA), -0.01 logMAR ±0.06 (SD); monocular distance corrected visual acuity (CDVA), 0.02 logMAR±0.06 (SD); binocular uncorrected near visual acuity (UNVA) at 40 cm, 0.05 logMAR ±0.08 (SD); binocular uncorrected intermediate visual acuity (UIVA) at 80 cm, -0.05 logMAR ±0.14 (SD); postoperative spherical equivalent, 0.26 D ±0.47 (SD); cylinder -0.34 D (±0.38); FineVision Micro F, binocular UDVA, 0.01 logMAR ±0.05 (SD) ; monocular CDVA, 0.03 logMAR ±0.06 (SD); binocular UNVA, 0.05 logMAR ±0.08 (SD) ; binocular UIVA, -0.05 logMAR ±0.12 (SD); spherical equivalent, 0.34 D ±0.50 (SD); cylinder -0.39 D ± 0.40 (SD). The IOLs were equivalent in achieving spectacle independence; 98% were “satisfied” to “very satisfied” with their IOL performance. Conclusions In this retrospective study with over 5000 patients, implantation of both trifocal IOL models provided good functional distance, intermediate and near visual acuity, resulting in high levels of both spectacle independence and patient satisfaction.
