To report our first clinical and patient-reported outcomes in the early postoperative period with a new model of trifocal diffractive intraocular lens (IOL). Pilot prospective analysis of the results of 26 eyes of 13 patients (age, 44-79 years) undergoing cataract surgery with implantation of the trifocal diffractive IOL Liberty 677MY (Medicontur Medical Engineering Ltd., Zsámbék, Hungary). The following clinical outcomes were evaluated during the first postoperative month: measurement of distance, intermediate and near visual acuity, binocular defocus curve, and level of spectacle independence, patient satisfaction, perception of photic phenomena, and difficulty in performing several vision-related daily tasks by means of a questionnaire. Mean binocular LogMAR uncorrected distance, intermediate and near visual acuities were -0.03 ± 0.13, 0.21 ± 0.16, and 0.16 ± 0.09, respectively. Furthermore, 100.0%, 84.6% and 92.3% of patients achieved a binocular corrected distance, distance-corrected intermediate and distance-corrected near visual acuity of 20/32 or better, respectively. In the defocus curve, visual acuities were better than 0.2 logMAR for defocus levels between +1.00 and -3.00 D. Spectacle independence was referred by all patients, with any of them reporting dissatisfaction with the outcome of the surgery. The postoperative vision did not lead to difficulties in the daily life in 92.3% of patients. Bothersome halos, glare or starbursts were only reported by only 7.7% of patients. The trifocal IOL evaluated provides a successful visual rehabilitation with minimal photic phenomena associated, leading to high levels of spectacle independence and patient satisfaction.
