Clinical Outcomes of Diffractive Aspheric Trifocal Intraocular Lens Implantation

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.

Clinical Outcomes of Diffractive Aspheric Trifocal Intraocular Lens Implantation

PURPOSE: To evaluate the clinical outcomes of patients with diffractive aspheric trifocal intraocular lens (AT.LISA tri839 MP(R) IOL, Carl Zeiss Meditec, Jena, Germany) implantation. METHODS: Forty eyes of 53 patients received phacoemulsification and implantation of AT.LISA tri839 MP(R) IOL (Carl Zeiss Meditec). 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 Optical Quality Analysis System (OQAS(R), Visiometrics, Castelldefels, Spain). 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 0.023 +/- 0.020, 0.155 +/- 0.091, and 0.139 +/- 0.069, respectively. The means of the objective scatter index, modulation transfer function cut-off value, Strehl ratio measured by OQAS(R) (Visiometrics) were 1.83 +/- 0.52, 33.58 +/- 14.27 cycle per degree and 0.18 +/- 0.11, respectively. Intermediate visual acuity did not fall sharply at defocus curve. CONCLUSIONS: Implantation of the diffractive aspheric trifocal intraocular lens in patients with cataracts provided excellent distant, intermediate and near visual acuities with high visual quality.
