A comparative evaluation of visual, refractive, and patient-reported outcomes of three diffractive trifocal intraocular lenses

@#OBJECTIVE: To compare the visual, refractive, and patient-reported outcomes of eyes implanted with one of 3 trifocal intraocular lenses (IOLs). METHODS: This is a cross-sectional, comparative, non-interventional study wherein subjects implanted with FineVision Micro F, AT LISA tri 839MP or AcrySof IQ PanOptix trifocal IOL after phacoemulsification were recruited. Manifest refraction, uncorrected and corrected visual acuity (VA) at distance, intermediate and near vision, contrast sensitivity, modulated transfer function (MTF) values and questionnaire answers were compared among the 3 groups using analysis of variance (ANOVA). RESULTS: Fifty-seven (57) eyes were included in the study: 21 eyes with FineVision (group A), 21 eyes with LISA tri (group B), and 15 eyes with PanOptix IOL (group C). The post-operative mean manifest spherical equivalent was -0.01D, -0.07D, and 0.05D, respectively (p=0.083). Uncorrected distance VA and best-corrected distance VA were similar among the groups. Groups A and C had better uncorrected and corrected intermediate VA at 80 cm and at 60 cm compared to group B. Group A had significantly better uncorrected near visual acuity than groups B and C (p=0.032). Mesopic contrast sensitivity testing showed group C had higher contrast sensitivities without glare in at the spatial frequency of 6 CPD (p=0.038) and with glare at 3 CPD (p=0.039) and at 12 CPD (p=0.009). MTF average height analysis showed that the group A had significantly superior resolution in far targets compared to groups B and C (p=0.001). At near targets, groups A and C had better resolutions compared to group B (p=0.017). There was no significant difference in patient satisfaction for far, intermediate and near VA among the groups. CONCLUSION: Eyes implanted with any of the 3 trifocal IOL designs achieved excellent uncorrected and bestcorrected distance, intermediate and near vision. FineVision and PanOptix provided significantly better intermediate vision than LISA tri at both 80 cm and 60 cm testing distance. FineVision had better near visual outcomes than PanOptix and LISA tri. Patient satisfaction was high in all 3 trifocal IOLS

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.

Myopic Shift after Implantation of a Novel Diffractive Trifocal Intraocular Lens in Korean Eyes

PURPOSE: To evaluate the clinical outcomes of cataract surgery using novel diffractive trifocal intraocular lenses (IOLs) in Koreans. METHODS: This was a retrospective, consecutive, interventional study of cataract surgery using POD FineVision IOL implantation. Complete ophthalmologic examinations were performed preoperatively and postoperatively. Defocus curves were assessed over a range of +1.5 to −4.0 diopters in 0.5-diopter steps at one month postoperatively. Uncorrected distant visual acuity, uncorrected intermediate visual acuity, uncorrected near visual acuity, corrected distant visual acuity, distant-corrected intermediate visual acuity, and distant-corrected near visual acuity were assessed one month postoperatively, and manifest refraction was performed during every visit. RESULTS: The study analyzed 31 eyes in 20 patients. There were statistically significant improvements in uncorrected distance visual acuity, uncorrected intermediate visual acuity, uncorrected near visual acuity, corrected distance visual acuity, distance-corrected intermediate visual acuity, and distance-corrected near visual acuity (p < 0.001). The final postoperative refractive outcomes showed statistically significant myopic shifts compared to the target refraction based on SRK/T, SRK-II, Haigis, and Hoffer Q formulas (p < 0.001). CONCLUSIONS: POD FineVision IOLs provide stable visual restoration with improvements of near and intermediate vision in presbyopic eyes. POD FineVision IOLs show myopic shift in a Korean population; therefore, surgeons should be cautious when selecting IOL power in such patients.
