One-Year Outcomes in a Large Series of Patients Following Implantation of an Extended Depth of Focus Intraocular Lens.

ABSTRACT

PURPOSE: To evaluate clinical outcomes 1 year after implantation of an extended depth of focus intraocular lens (IOL) in a large series of patients. METHODS: Outcomes of patients who underwent refractive lens exchange or cataract surgery with the implantation of the AT LARA 829MP IOL (Carl Zeiss Meditec AG) were retrospectively reviewed. The near (40 cm), intermediate (66 cm), and distance visual acuity, refractive outcomes, and cumulative rate of adverse events and secondary procedures were evaluated at 12 months postoperatively. RESULTS: A total of 1,894 eyes of 977 patients were implanted with the AT LARA 829MP IOL, with 62.1% of eyes available for the 12-month visit. The overall secondary procedure rate for the whole cohort was NdYAG = 7.8%, laser vision correction = 7.5%, and IOL explantation = 0.63%. The reasons for IOL exchange were intraoperative complications (3 eyes/0.16%) and quality of vision issues (9 eyes/0.48%). Of all eyes available for the 12-month visit that did not undergo laser vision correction or an IOL exchange, 72.0% had monocular uncorrected distance visual acuity of 20/20 or better and the percentage of eyes with monocular uncorrected intermediate and near visual acuity of 20/50 or better was 96.2% and 81.0%, respectively. At 12 months postoperatively, 87.6% of eyes were within ±0.50 diopters of emmetropia. No change in refraction occurred between the 6- and 12-month postoperative visits. CONCLUSIONS: The AT LARA 829MP extended depth of focus IOL is able to provide functional distance, intermediate, and near visual acuity. Complications related to the platform of the IOL were uncommon. [J Refract Surg. 2021;37(6)380-388.].
