Abstract
PURPOSE: To compare the optical performance and quality of life after implantation of a new progressively apodized diffractive multifocal intraocular lens (IOL) and report the visual and patient-reported outcomes and contrast sensitivity. SETTING: Csolnoky Ferenc Hospital, Veszprem, Hungary. DESIGN: Prospective case series. METHODS: Patients had bilateral implantation of the trifocal IOL during cataract surgery. The preoperative corrected distance visual acuity (CDVA) and postoperative uncorrected distance visual acuity (UDVA), CDVA, uncorrected (UIVA) and corrected (CIVA) intermediate visual acuities, and uncorrected (UNVA) and corrected (CNVA) near visual acuities (all logarithm of the minimum angle of resolution) were collected. Contrast sensitivity, slitlamp photographs for evaluation of posterior capsule opacification, and a quality-of-vision questionnaire were assessed. RESULTS: The study comprised 100 eyes (50 patients). The mean postoperative UDVA was 0.01 at 3, 6, 12, and 24 months. The mean CDVA was -0.02 ± 0.03 (SD) at 6 months, -0.04 ± 0.05 at 1 year, and 0.06 ± 0.05 at 2 years. The mean UIVA was 0.05 ± 0.11, 0.04 ± 0.09, and 0.06 ± 0.11, respectively. The mean CIVA was -0.01 ± 0.07, -0.02 ± 0.06, and -0.01 ± 0.07, respectively. The mean UNVA was 0.08 ± 0.08, 0.07 ± 0.08, and 0.10 ± 0.09, respectively. The mean CNVA was 0.03 ± 0.06 at 3 months, 0.04 ± 0.05 at 1 year, and 0.05 ± 0.07 at 2 years. The mesopic and photopic contrast sensitivity values were within the upper normal range for age-matched values. CONCLUSIONS: Bilateral implantation of a new trifocal IOL with centralized diffractive rings provided good functional vision at all distances. The levels of spectacle independence and patient satisfaction were high with minimal dysphotopsia symtoms. Crown
