“…Visual performance was evaluated 1 month after surgery because previous studies have not found significant differences in visual acuity one, three and 6 months after surgery in patients receiving trifocal lens [4, 6, 7, 10, 15]. 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.…”

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.

“…1 The development of trifocal IOLs addresses this problem and provides good results that are reported by several authors previously. [2][3][4] Despite the various numbers of commercial multifocal IOLs available in today's market, most of them are based on diffractive platforms that use slightly different focal points for far, intermediate, and near activities. The new Acrysof PanOptix trifocal IOL (Alcon Surgical, Inc.) seeks low pupillary dependence and aims to improve intermediate vision with a substantial range and an optimal one at 60 cm, 5 the distance most used recently in daily life with the massive development and rising usage of handheld devices and computers.…”

“…Several studies have demonstrated that the generation of a third focal point with an IOL using diffractive optics does not induce an increase in the incidence of visual disturbances or a deterioration of the visual quality. 1 , 4 – 6 Likewise, as trifocal IOLs provide a complete visual restoration, including far, intermediate, and near distances, high levels of patient satisfaction have been reported with them. 7 – 10 …”

PurposeTo evaluate visual outcome, reading performance, contrast sensitivity, and patient satisfaction after cataract surgery with implantation of a diffractive trifocal intraocular lens (IOL).Patients and methodsA total of 42 eyes (21 patients) underwent cataract surgery with implantation of the trifocal IOL AT LISA tri 839MP. Visual acuity, contrast sensitivity, and patient satisfaction were evaluated 3 months postoperatively. Reading performance was evaluated at 3 months postoperatively with the MNREAD charts.ResultsAll eyes achieved a 3-month postoperative monocular uncorrected distance visual acuity of 0.10 logMAR or better (Snellen 20/25). Likewise, 97.62% and 85.71% of eyes achieved a postoperative monocular uncorrected intermediate, and near visual acuity of 0.20 logMAR (Snellen 20/30) or better. All patients achieved postoperative binocular uncorrected distance visual acuity, uncorrected intermediate, and uncorrected near visual acuity of 0.20 logMAR (Snellen 20/30) or better. Mean photopic reading acuity and speed were 0.24±0.07 logMAR and 177.61±20.67 words per minute, respectively. Postoperative contrast sensitivity values were within the ranges of normality for all spatial frequencies evaluated. Postoperative spectacle independence and patient satisfaction was very high, with most of the patients reporting a good or very good visual quality at far, intermediate, and near distances. All patients would choose the same lens again.ConclusionThe evaluated trifocal IOL provides an effective restoration of the visual function after cataract surgery, with high levels of distance, intermediate, and near visual acuity, strong reading performance, and patient satisfaction.
