Initial Clinical Outcomes of a New Extended Depth of Focus Intraocular Lens.



To evaluate clinical and patient-reported outcomes of a new extended depth of focus intraocular lens (IOL).


Data of patients treated between September 2017 and September 2018 who underwent a refractive lens exchange/cataract surgery with an implantation of the AT LARA 829MP IOL (Carl Zeiss Meditec AG, Jena, Germany) and attended the 1-week, 1-month, and 3-month follow-up visit were reviewed.


At 3 months, the percentage of eyes within ±0.50 diopters (D) of emmetropia was 86.7%. The mean binocular uncorrected distance visual acuity was -0.05 ± 0.09 logMAR and the mean binocular unaided near vision was 0.26 ± 0.14 logMAR. Of all patients, 90.3% were satisfied with their vision. The percentage of patients spectacle-free for near and distance vision was 83.6% and 95.4%, respectively. On a scale from 1 (no difficulty) to 7 (severe difficulty), there was an average 1.2 to 1.4 units increase in glare, halo, and starburst between the preoperative and 1-month visit, and a decrease of 0.2 to 0.3 units between the 1- and 3-month visit.


The new extended depth of focus IOL provided reasonable unaided near and distance vision, as well as spectacle independence and patient satisfaction. Some optical side effects were reported in the early postoperative period. [J Refract Surg. 2019;35(7):426-433.].
