“…When analyzing the reading performance, it is also important to make sure the reading acuity was measured with a reading speed of at least 80 wpm, because this threshold demonstrates that the print size was read easily without effort. 8 In the current study, all reading acuity values were measured with a reading speed of at least 80 wpm (range: 81 to 424 wpm), suggesting the patients' ability to perform daily tasks at intermediate and near distances comfortably.…”

“…Currently, only a limited number of studies have assessed the reading acuity after implantation of different multifocal IOLs using this device. [8][9][10]22,23 Attia et al 10 examined the reading ability after bilateral implantation of another EDOF lens, the Tecnis Symfony IOL, and found a distance-corrected intermediate reading acuity of 0.00 logMAR at a fixed distance of 80.1 cm and 0.08 logMAR at a subjectively preferred distance of 65.0 cm (15 patients, 2 to 6 months postoperatively). For near, the distance-corrected near reading acuity was 0.29 logMAR at a fixed distance of 40.6 cm and 0.16 logMAR at a subjectively preferred distance of 41.7 cm.…”

“…The measurement principles of this device had been extensively described in our previous studies. [8][9][10] Furthermore, the subjective perception of photic phenomena was evaluated using a computer-based software Halo and Glare Simulator (Eyeland Design Network GmbH, Vreden, Germany). The measurement method of this simulator has also been explained in detail in a previous study.…”

here are currently numerous different multifocal intraocular lens (IOL) models available in the market. Some are bifocal or trifocal, whereas recent ones claim to generate a so-called extended depth of focus (EDOF), which describes the ability of the lens to provide a continuous range of vision across multiple distances. Typically, multifocal lenses are implanted bilaterally. Alternatively, surgeons can "mix-and-match," a technique that describes an asymmetrical implantation of two different IOL models as an attempt to reinforce their advantages and thereby improve the visual outcomes. 1,2 Numerous studies have reported visual results after mixing and matching different multifocal IOLs. 3-7 In this study, we present the clinical outcomes after asymmetrical implantation of an EDOF IOL and a segmental-refractive bifocal lens.

“…Similarly, contrast sensitivity has also been found to be stable between 1 and 12 months postoperatively [9]. As regards the distances at which intermediate and near visual acuity were evaluated, studies performed with a reading desk have reported that the preferred intermediate distance ranges between 61.50 cm and 64.20 cm [14, 16]; 60 cm was chosen because it is very similar to this preferred range and has been already used in other publications [4, 5, 15], facilitating comparison with studies performed with other IOLs. Similarly, the mean reported preferred near distance ranges between 34.6 cm and 38.70 cm [14, 16] and 33 cm was chosen as the distance to evaluate near vision as used in one other study which compared two trifocal IOLs [15].…”

BackgroundToday, patients often expect to achieve spectacle independance after cataract surgery. New trifocal intraocular lenses have been developed to try and fullfill this demand. The purpose of this study is to report the short-term visual outcomes of a new trifocal intraocular lens (AcrySof PanOptix™).MethodsConsecutive adult patients undergoing cataract surgery with bilateral implantation of the study intraocular lens in a private practice clinic were considered for inclusion. Exclusion criteria were the presence of other ocular pathologies or preoperative astigmatism >1.5 diopters (D). Patients with intraoperative complications were excluded from analysis. One month after surgery patients underwent: monocular defocus curve; monocular and binocular uncorrected visual acuity in photopic and mesopic conditions, for far (4 m), intermediate (60 cm) and near (33 cm) distances and binocular contrast sensitivity. Patients completed a visual satisfaction questionnaire between 9 and 12 months after surgery.ResultsOne hundred and sixteen eyes of fifty-eight patients receiving bilateral implantation of the study intraocular lens were analysed. Mean binocular uncorrected visual acuity in photopic conditions was 0.03 LogMAR for far, 0.12 for intermediate and 0.02 for near distances. All patients achieved a binocular uncorrected visual acuity better than 0.3 LogMAR (20/40 Snellen equivalent) for distance and near vision and 94.8% of patients for intermediate vision. Mesopic binocular uncorrected visual acuity values were similar to photopic values. The monocular defocus curves showed that the best visual acuity was reached at a vergence of 0.00D. Visual acuity dropped slightly at −1.00D and peaked again at −2.00D. Visual acuities better than 0.2 LogMAR were maintained between −2.50D and +0.50D. Contrast sensitivity was high and similar in photopic and mesopic conditions. As regards patient-evaluated outcomes, only 2 patients (3.4%) were fairly dissatisfied with their sight after surgery. Three patients (5.1%) reported the need for spectacle correction for certain activities. All other patients (94.8%) reported never using spectacle correction.ConclusionsThe PanOptix trifocal IOL provides good short-term visual outcomes, with good intermediate performance and excellent patient-reported satisfaction. The similar values achieved in mesopic and photopic conditions in binocular uncorrected visual acuity and contrast sensitivity suggest low pupillary dependence for light distribution.Trial registration number ISRCTN60143265, retrospectively registered on the 24th of April 2017.

“…В последние годы на рынке стали доступны новые модели панфокальных (panfocal) ИОЛ, обеспечивающие пациенту больший комфорт при чтении на среднем расстоянии, чем более ранние бифокальные ИОЛ. Первые результаты имплантации таких ИОЛ, как FineVision® (Physiol, Бельгия) и AT LISA tri839MP® (CarlZeiss Meditec, Германия), являются весьма обнадеживающими [17][18][19][20][21][22][23][24][25][26][27]. С целью улучшения передачи света и его распределения между тремя фокусными точками была разработана новая мультифокальная ИОЛ -AcrySof PanOptix® trifocal (Alcon, США) [28].…”

Purpose. Evaluation of short-term (up to 9 months) results of new one-piece aspherical diffractive trifocal intraocular lens implantation. Patients and Methods. A prospective, open-label study included 65 patients (100 eyes) with presbyopia, who received cataract extraction with the implantation of a new IOL AcrySof PanOptix® trifocal. The average age of the patients was 60.0 ± 12.1 years. 35 patients underwent bilateral correction with multifocal IOLs, and 30 had a monolateral correction. In 21 % (n = 21) cases, femtolaser support of cataract extraction was performed. In 9 eyes (9 %) the primary posterior capsulorhexis was performed. The range of optical power of implanted IOLs was 13 to 30 D. The follow-up period was from 6 to 9 (6.8 ± 0.9) months.Results. On the 1 day after the MIOL implantation, an UCIVA increase was from 0.22 ± 0.19 to 0.76 ± 0.23 (p < 0.05), at follow-up to 6 months up to 0.85 ± 0.22. One day after surgery, the UCIVA increased from 0.23 ± 0.19 to 0.7 ± 0.25 (p < 0.05), with following raise up to 0.84 ± 0.24 in the maximum follow-up period of 6 months. UCFVA in the preoperative period was 0.27 ± 0.23, with an increase to 0.78 ± 0.23 (p < 0.05) for 1 day and 0.93 ± 0.18 at 6 months. The BCNVA increase was from 0.56 ± 0.25 before surgery to 0.8 ± 0.19 on the 1st day after cataract removal (p < 0.05) and 0.98 ± 0.16 at the 6 months follow-up period. Similar data (0.58 ± 0.29, 0.82 ± 0.21, and 0.95 ± 0.14) was noted for BCIVA. An BCFVA increase was from 0.71 ± 0.28 in the preoperative period to 1.0 ± 0.04 (p < 0.05) after 6 months. The primary endpoint of the study (BCFVA = 1.0) in the group was achieved in 83 % of cases (n = 83). The effect of glare was noted in 17 patients (26.1 %), halo in 9 (13.8 %), driving difficulties in 6 (9.2 %). The overwhelming majority of patients (96.9 %) rated the result of the operation as “excellent” (n = 51, 78.5 %) and “good” (n = 14, 21.5 %).Conclusion. Implantation of the examined IOL is associated with a high efficiency for near, intermediate distance and far vision correction. A new trifocal IOL may be recommended for use in clinical practice. Further comparative studies including other multifocal IOLs are needed to determine the indications and contraindications for its implantation.
