“…This seems logical, as the presence of photic phenomena with diffractive multifocal IOLs seems to be related to the diffractive component rather than residual refractive error. According to theoretical simulations, a double-halo formation due to two non-focused powers can be expected with the trifocal IOL evaluated in the current study [ 25 ]. Law et al [ 6 ] found that the halos associated with this IOL were well-tolerated, and their perception was reduced over time.…”

PurposeTo evaluate visual outcomes following implantation of a trifocal diffractive intraocular lens (IOL) and to analyze their correlation with patient satisfaction and ease of performing daily tasks.MethodsThis was a prospective study enrolling 100 eyes of 50 patients undergoing cataract surgery with implantation of trifocal IOL AT LISA tri 839MP. Visual and refractive outcomes were evaluated during a 3-month follow-up. Postoperatively, a questionnaire was used to evaluate patient satisfaction with regard to surgical outcome, spectacle independence, perception of photic phenomena, and ease of performing some vision-related activities.Results A total of 91%, 87%, and 79% of eyes achieved a monocular uncorrected distance, near, and intermediate visual acuity of 0.1 logarithm of the minimum angle of resolution or better, respectively. After the surgery, 96% of the patients could perform their daily activities without problems. The mean spectacle independence scores for reading, doing computer work, and for distance were 10.33 ± 12.47, 5.71 ± 11.90, and 3.92 ± 9.77, respectively (scale: 0 = no spectacles needed; 40 = spectacles always needed). No correlation was found between spectacle independence and visual outcome (-0.101 ≤ r ≤ 0.244, p ≥ 0.087). Mean scores (0 = no symptoms; 40 = strong symptoms) for glare at night, ghost images, and halos were 15.15 ± 12.02, 4.49 ± 7.92, and 13.34 ± 10.82, respectively. No correlation was found between photic phenomena and visual outcome (-0.199 ≤ r ≤ 0.209, p ≥ 0.150). A total of 80% of patients reported satisfaction with the surgery outcome, and 86% would recommend the surgery to friends and family.ConclusionsImplantation of the AT LISA tri 839MP IOL after cataract surgery provides effective visual restoration associated with a minimal level of photic phenomena, a positive impact on the performance of vision-related daily activities, and a high level of postoperative patient satisfaction.

“…Halos may cause a high level of dissatisfaction in spite of perfect refraction and above-average acuity values and can lead to the necessity of explanting the IOL [ 12 ]. Alba-Bueno et al [ 13 ] published a study aimed at presenting the theoretical and experimental characterization of the halo in multifocal IOLs. These authors stated that the most noticeable characteristic of halos with the trifocal IOL AT LISA tri 839MP was the double-halo formation due to the 2 nonfocused powers.…”

Purpose. To evaluate visual, refractive, and contrast sensitivity outcomes, as well as the incidence of pseudophakic photic phenomena and patient satisfaction after bilateral diffractive trifocal intraocular lens (IOL) implantation. Methods. This prospective nonrandomized study included consecutive patients undergoing cataract surgery with bilateral implantation of a diffractive trifocal IOL (AT LISA tri 839MP, Carl Zeiss Meditec). Distance, intermediate, and near visual outcomes were evaluated as well as the defocus curve and the refractive outcomes 3 months after surgery. Photopic and mesopic contrast sensitivity, patient satisfaction, and halo perception were also evaluated. Results. Seventy-six eyes of 38 patients were included; 90% of eyes showed a spherical equivalent within ±0.50 diopters 3 months after surgery. All patients had a binocular uncorrected distance visual acuity of 0.00 LogMAR or better and a binocular uncorrected intermediate visual acuity of 0.10 LogMAR or better, 3 months after surgery. Furthermore, 85% of patients achieved a binocular uncorrected near visual acuity of 0.10 LogMAR or better. Conclusions. Trifocal diffractive IOL implantation seems to provide an effective restoration of visual function for far, intermediate, and near distances, providing high levels of visual quality and patient satisfaction.

“…Diffractive multifocal IOLs provide two distinct foci for distance and near, with compromised intermediate visual acuity. [ 5 ] Low add multifocal lenses may help in achieving superior unaided intermediate vision but may compromise near visual acuity. [ 6 ] The Tecnis Symfony IOLs with its proprietary echelette design provides an elongated range of focus rather than individual focal points, resulting in potentially superior intermediate vision and reduced photic phenomena such as glare and halos.…”
