Performance of the Acri.Smart 46S intraocular lens in pediatric microincision cataract surgery

Abstract

To evaluate the performance of the microincision Acri. Smart 46S intraocular lens (IOL) (Acri.Tec) in pediatric cataract surgery. Department of Ophthalmology, Ludwig-Maximilians University, Munich, Germany. Thirty-two consecutive eyes of 22 children who had cataract surgery with planned IOL implantation were retrospectively analyzed. Intraoperative and postoperative IOL performance, posterior capsule opacification (PCO) formation, best corrected far and near visual acuities, and astigmatism were analyzed. The minimum follow-up was 12 months. The median patient age was 4.5 years (range 2 to 13 years) and the median follow-up, 21 months (range 12 to 29 months). In 94% of eyes, the IOL was implanted in the capsular bag; in 6%, it was placed in the ciliary sulcus. A primary posterior capsule opening was created in 12.5% of eyes. The posterior capsule was intact at the end of surgery in 81% of eyes. Capsule rupture occurred during lens aspiration in 3% of eyes, and a primary capsular defect was present in a patient with traumatic cataract. Posterior capsule opacification that required a second intervention during the follow-up period developed in 35% of eyes. All IOLs were well centered and had a clear optical axis at the end of follow-up. The Acri. Smart (46S) IOL was found to be suitable for pediatric bimanual microincision cataract surgery. The feasibility of inserting the IOL through of the sub-2.0 mm paracentesis minimizes manipulation of the juvenile eye.
