“…It has been shown in many studies that there may be a decrease in contrast sensitivity, especially at night, due to the splitting of light in patients implanted with multifocal intraocular lenses. However, the differences between results or the use of different tests make it di cult to evaluate the contrast sensitivity of patients [14][15][16][17][18]. In our study, we also found that contrast sensitivities in the Trinova group were to be lower than the Eyhance group in all cycles/degrees.…”

Purpose: To evaluate and compare the clinical results of sinusoidal vision trifocal intraocular lens (IOL) (AcrivaUD Trinova) and monofocal extended depth of focus (EDOF) IOL (Tecnis Eyhance ICB00) Methods: This study included 98 eyes of 65 patients implanted with sinusoidal vision trifocal IOL and 79 eyes of 53 patients implanted with monofocal EDOF IOL. The following were evaluated; Uncorrected distance(UDVA), intermediate (UIVA), near visual acuity (UNVA), corrected distance(CDVA), intermediate(CIVA) , near visual acuity (CNVA), halo, glare, ocular aberrations, contrast sensitivity. In addition, The National Eye Institute 25-Item Visual Function Questionnaire (NEI-VFQ 25) results of patients were analysed.Results: Three months postoperatively, there were no differences between the groups in terms of UDVA and UIVA(respectively, p=0.780 and p=0.317). Near vision was found to be better for the Trinova group than for the Eyhance group(p<0.001). Trinova IOL provided better contrast sensitivity at all spatial frequencies than Eyhance IOL (p<0,001). Halo perception was reported for only six eyes, all of which were in the Trinova group (6.9%). Glare perception was found to be more common in the Trinova group (15 eyes(17.2%)), than in the Eyhance group(four eyes(5.3%)). With regard to the composite score of NEI-VFQ 25, no significant difference was found between the groups. In the analyses of subgroups, the near activities score was higher in the Trinova group, but distance activities and driving scores were higher in the Eyhance group (p=0.201).Conclusion: Both lenses have been shown to have satisfactory levels of distance and intermediate vision, with high levels of patient satisfaction.

“…When applying the manufacturers' conversion guidelines, individual values could be converted into values suitable for statistical analysis; ie, the area under the log contrast sensitivity function (AULCSF) curve. 16 The uncorrected reading acuity and reading performance were measured at baseline and 3 months postoperatively with the Dutch Radner reading chart 17 (Rotterdam Eye Hospital, Rotterdam, the Netherlands) using the Salzburg Reading Desk (SRD Vision). 18 The Radner reading chart comprises standardized sentences, allowing evaluation in patients with different levels of education.…”

“…pupil size in different photic conditions. The study by Eppig et al evaluated contrast sensitivity in 11 different aspheric IOL designs and concluded that mesopic vision benefits more in aspheric IOL than photopic vision, especially due to the correction of spherical aberration at large pupil diameters, which is supported by the findings of Crnej [19,20]. Interestingly, both Symfony and AtLisa tri 839 MP have larger diffractive zone (6.0 mm) than PanOptix (4.5 mm) and lower energy utilization (85-86%) than PanOptix (up to 88%) which makes functional vision to be more dependent on pupil size or lightning conditions and provides worse CS [14].…”

Purpose To compare visual outcomes after implantation of AtLisa tri 839 MP and Symfony intraocular lenses (IOLs). Methods All subjects underwent sequential bilateral cataract extraction with AtLisa tri 839 MP or Symfony IOL implantation. The design is prospective case series. Each group consists of 20 patients (40 eyes). At 1 year postoperatively, the following parameters were analysed: binocular uncorrected visual acuity (log MAR): for distance (UDVA) at 4 m, for intermediate distances (UIVA) at 60, 70, 80 cm and for near (UNVA) at 40 cm, defocus curve, mesopic and photopic contrast sensitivities (CSs), spectacle independence, visual function test questionnaire modified VFQ-25), photopic phenomena and postoperative complications. Results In the AtLisa tri 839 MP group, the mean binocular UNVA and UIVA were significantly better than in the Symfony group (UNVA: − 0.01 ± 0.04 vs. 0.21 ± 0.15; p = 0.000; 60 cm UIVA: − 0.01 ± 0.04 vs. 0.09 ± 0.09, p = 0.001; 70 cm UIVA − 0.05 ± 0.06 vs. 0.11 ± 0.08, p = 0.002; 80 cm UIVA − 0.01 ± 0.06 vs. 0.15 ± 0.08, p = 0.019). There were no significant between-group differences in the mean binocular UDVA and CS, with one exception: the mean binocular distance CS (18 cpd) under mesopic conditions was significantly better in the Symfony group than in the AtLisa tri 839 MP group (1.39 ± 0.22 vs. 1.17 ± 0.27; p = 0.015). The defocus curve analysis revealed significant between-group differences at vergences of 2.0 to − 4.0 D (p < 0.05), except for 2.0, 1.0, 0 and − 1.5. All subjects in AtLisa tri 839 MP group and 18 subjects (90%) in Symfony group were spectacle independent. Patients from both groups highly rated their overall vision quality in the VFQ-25 (1.67 ± 0.47 vs. 1.85 ± 0.5 in the Symfony and AtLisa tri 839 MP group, respectively, p = NS). The scores for daytime driving (1.00 ± 0.00 vs. 1.21 ± 0.36; p = 0.002), night driving (1.57 ± 0.55 vs. 2.13 ± 1.15; p = 0.027) and difficult situation driving (1.14 ± 0.31 vs. 1.53 ± 0.56; p = 0.049) were significantly better in the AtLisa tri 839 MP group than in the Symfony group. The incidence and perception level of halo and glare were significantly reduced (p = 0.00) in the Symfony group as compared to the AtLisa tri 839 MP group. The postoperative course was uneventful in all subjects. Conclusions Visual outcomes achieved with both IOLs are comparable. In both groups, 90% of patients achieved spectacle independence. Whereas the AtLisa tri 839 MP IOL implantation was associated with slightly better intermediate distance VA and significantly better near VA, photic phenomena were less perceived by patients with Symfony IOLs.
