“…Mean UDVA, UIVA (80 cm) and UNVA (40 cm) values of 0.01 (Snellen 20/20), 0.14 (Snellen 20/27), and 0.21 (Snellen 20/30) logMAR were obtained 3 months after surgery. This is consistent with the visual outcomes reported by Mojzis et al 14 in a previous series of cases evaluating the results of the same IOL with toricity 3 months after its implantation, with mean logMAR UDVA, UIVA (80 cm), and UNVA (40 cm) values of 0.03 (Snellen 20/20), 0.08 (Snellen 20/25), and 0.16 (Snellen 20/28), respectively. Likewise, Kretz et al 15 reported in another study mean 3-month postoperative UDVA, UIVA, and UNVA values of 0.13±0.15 (Snellen 20/26), 0.08±0.15 (Snellen 20/24), and 0.13±0.18 logMAR (Snellen 20/26), respectively.…”

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.

“…Although trifocal IOLs were developed to avoid this valley in intermediate vision, previous studies have also shown the presence of valleys between the three peaks of maximum optical quality corresponding to far, intermediate, and near distance. 7,[20][21][22][23][24] However, from a theoretical point of view, the EDOF IOL is more restrictive in terms of considering visual acuity for all distances because it causes a plateau between far and intermediate distance in the through-focus MTF curve. Specifically, an increased depth of focus ensures that the intermediate visual quality is higher than a certain level, which can be somewhat lower than that at far distance.…”

“…Zheleznyak et al konnten zeigen, dass ein unkorrigierter Hornhautastigmatismus und Aberrationen höherer Ordnung (HOA) bei pseudophaken Augen die Abbildungsqualität von diffraktiven presbyopiekorrigierenden Linsen stark beeinträchtigen [12]. Aus diesem Grund wurden torische Varianten der trifokalen diffraktiven Linsen entwickelt, die neben dem Verteilen des Lichtes auf 3 Brennpunkte auch den vorbestehenden Hornhautastigmatismus korrigieren [13]. Mit diesen trifokal-torischen IOL lassen sich vergleichbare Ergebnisse erzielen wie mit apodisierten diffraktiven bifokal-torischen IOL [14].…”

To evaluate and compare the visual performance of a trifocal and a trifocal-toric intraocular lens (IOL) based on the same diffractive platform. Prospective non-randomized comparative study enrolling 142 eyes of 77 patients (age 40-73 years) undergoing uneventful phacoemulsification lens surgery. Two groups were differentiated according to the implanted IOL: trifocal group, 98 eyes (50 patients) implanted with the trifocal diffractive IOL AT LISA tri 839MP (Carl Zeiss Meditec), and trifocal-toric group, 44 eyes (27 patients) implanted with the trifocal-toric diffractive IOL AT LISA trifocal-toric 939MP (Carl Zeiss Meditec). Visual and refractive changes were evaluated 3 months postoperatively. No significant differences between groups were found in postoperative refraction (p ≥ 0.144), monocular and binocular uncorrected intermediate visual acuity (UIVA; p = 0.519 and 0.398, respectively) and binocular uncorrected near visual acuity (UNVA; p = 0.073). In contrast, significantly better monocular and binocular uncorrected distance visual acuity (UDVA; p ≤ 0.002), as well as monocular UNVA (p = 0.005), were found in the trifocal group. A postoperative spherical equivalent within ± 1.00 D was found in 98 % and 100 % of eyes in the trifocal and trifocal-toric groups, respectively. Postoperative binocular UDVA, UIVA and UNVA of 20/30 or better were found in 100, 95 and 100 % of eyes, and in 96.3, 95.8 and 90.9 % of eyes in the trifocal and trifocal-toric groups, respectively. The evaluated trifocal and trifocal-toric IOLs both provide a successful restoration of the visual function after cataract surgery, with good levels of refractive precision, as well as UIVA and UNVA.
