Delivery Characteristics of the Preloaded POB‐MA 877PA Intraocular Lens System: Comparison of 2 Incision Sizes

Abstract

Purpose: To obtain real‐world data regarding the delivery characteristics of a preloaded delivery system, the Bi‐Flex POB‐MA 877PA, and to compare them in 2 main port incision sizes: 2.4 mm and 2.75 mm. Design: Prospective multicenter observational cohort study. Methods: Consecutive elective phacoemulsification and intraocular lens surgeries using the POB‐MA 877PA implant were performed by a single experienced surgeon between December 2017 and April 2018. Patients were divided into 2 groups with group 1 and 2 underwent phacoemulsification through a main port size of 2.4 mm and 2.75 mm, respectively. Delivery characteristics were recorded, with a main outcome defined as lens delivery entirely into the capsular bag using the preloaded injector without additional manipulation. Other variances were classified as minor or major issues depending on lens or anatomical damage or requirement to replace device. Results: A total of 110 total cases were included, with 59 cases in group 1 (2.4 mm) and 51 cases in group 2 (2.75 mm). Group 2 had a significantly lower proportion of cases that required secondary manipulation of the lens than group 1 [8 (15.7%) cases vs 24 (40.7%) cases; P < 0.05]. In groups 1 and 2, 3 (5.1%) and 3 (5.9%) cases had major issues, respectively. Conclusions: The delivery characteristics of the POB‐MA 877PA intraocular lens systems are different in the 2.4‐mm and 2.75‐mm main port incisions, with a lower proportion of cases requiring secondary manipulation in the 2.75‐mm incision size. Despite its preloaded nature however, there are still delivery issues with these intraocular lens systems.
