Clinical Outcomes of Diffractive Aspheric Trifocal Intraocular Lens Implantation

ABSTRACT

PURPOSE: To evaluate the clinical outcomes of patients with diffractive aspheric trifocal intraocular lens FineVision Pod F IOL (PhysIOL, Liège, Belgium) implantation. METHODS: Thirty eight eyes received phacoemulsification and implantation of FineVision Pod F IOL. Uncorrected distant visual acuity (UDVA), uncorrected intermediate visual acuity (UIVA), uncorrected near visual acuity (UNVA), refractive values, and defocus curve were evaluated at postoperative 1 month and 3 months. Optical quality was evaluated with the contrast sensitivity test, OQAS® (Optical Quality Analysis System, Visiometrics, Cerdanyola del Vallès, Spain) and questionnaire. RESULTS: At the 3-month postoperative follow-up, the mean spherical equivalent was 0.01 ± 0.31 D and the mean UDVA, UIVA and UNVA were 0.04 ± 0.07, 0.19 ± 0.12, and 0.04 ± 0.07, respectively. Mean contrast sensitivities at 0.75, 1.5, 3, 6, 12, and 18 cycles per degrees were 2.00 ± 1.54, 2.16 ± 1.60, 2.25 ± 1.76, 2.16 ± 1.83, 1.52 ± 1.47 and 1.03 ± 0.95 respectively and mean objective scatter index by OQAS® (Optical Quality Analysis System, Visiometrics) was 1.54 ± 0.74. In satisfaction analysis, general satisfaction with surgery was 89% and spectacle independence were 89% at far, 78% at intermediate and 83% at near distance. Postoperative dissatisfaction factors were dryness (36%), glare at night (32%), halo (18%). CONCLUSIONS: The FineVision Pod F IOL showed excellent distant and near visual acuities with an effective intermediate visual acuity. The eyes with FineVision Pod F IOL expected to achieve the favorable visual outcome and patient satisfaction.
