ABSTRACT
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.

Mentions: Figure 3 displays the intermediate and near visual outcomes obtained in the analysed sample. As shown, all patients achieved a binocular UIVA of 0.10 LogMAR or better, whereas 70% of eyes achieved this level of UIVA monocularly. Likewise, 85% of patients achieved a binocular UNVA of 0.10 LogMAR or better in the analysed sample, and all eyes achieved a monocular UNVA of 0.20 LogMAR or better (Figure 3). Mean postoperative preferred reading distance was 38 cm, ranging from 32 to 40 cm. At this distance, all patients achieved an uncorrected binocular visual acuity of 0.1 LogMAR or better (Figure 3).
