Abstract

BACKGROUND: Clinical evaluation of an extended depth of focus (EDOF) intraocular lens (IOL) regarding visual performance at various distances, reading performance on an electronic reading desk, and depth of focus on the defocus curve. METHODS: In this prospective study, 30 eyes of 15 patients who received the Tecnis Symfony IOL (Abbott Medical Optics, Inc., Santa Ana, CA) were examined 3.60 ± 1.54 months postoperatively. Uncorrected and corrected distance (UDVA and CDVA), uncorrected and distance-corrected intermediate (UIVA and DCIVA), and uncorrected and distance-corrected near (UNVA and DCNVA) visual acuity were determined. The defocus curve was performed with distance correction. Furthermore, the reading acuity at the preferred near and intermediate distances was measured with consideration of the reading distance, speed, and print size. A subjective questionnaire was also administered. RESULTS: Results showed a median UDVA of 0.03 logMAR or 20/21.43 Snellen (range: 0.44 to -0.18 logMAR or 20/55.08 to 20/13.21 Snellen), UNVA of 0.20 logMAR or 20/31.70 Snellen (range: 0.46 to 0.00 logMAR or 20/57.68 to 20/20 Snellen), and UIVA of -0.03 logMAR or 20/18.67 Snellen (range: 0.14 to -0.18 logMAR or 20/27.61 to 20/13.21 Snellen). The improved performance at intermediate distance was confirmed by an uncorrected reading acuity of 0.09 logMAR or 20/24.61 Snellen (range: 0.36 to 0.00 logMAR or 20/45.82 to 20/20.00 Snellen) at a preferred intermediate distance of 64.10 cm (range: 52.0 to 75.0 cm). The defocus curve showed an extended range of visual acuity of 0.10 logMAR or better between 1.00 and -1.50 diopters. CONCLUSIONS: The EDOF IOL design provided a wide range of improved visual and reading function between far and intermediate distances and also improved near visual acuity. Patients reported a high rate of satisfaction and spectacle independence at the various distances. [J Refract Surg. 2017;33(10):664-669.].
