SURGICAL OUTCOMES AND INTRAOPERATIVE PARAMETERS OF THREE-DIMENSIONAL VISUALIZATION SYSTEM VERSUS CONVENTIONAL MICROSCOPES FOR MACULAR SURGERY IN HIGHLY MYOPIC EYES: A Prospective Randomized Clinical Trial.

Abstract

To investigate the surgical outcomes and intraoperative parameters of 3D visualization system for macular diseases in highly myopic eyes. In this single-center, prospective, randomized, comparative interventional study, 40 highly myopic eyes (axial length > 26 mm) were randomly assigned to either a 3D visualization system or a conventional microscope group. Surgical outcomes and intraoperative parameters, including the number of indocyanine green injections, surgical time, and epiretinal membrane/internal limiting membrane peeling time, were compared. The 3D group required significantly fewer indocyanine green injections (1.3 ± 0.5 vs. 2.3 ± 0.7, P < 0.001), had shorter epiretinal membrane/internal limiting membrane peeling times (522.8 ± 258.0 vs. 751.8 ± 320.2 seconds, P < 0.05), and experienced fewer intraoperative retinal hemorrhages (0 vs. 7 cases, P < 0.05) compared with the conventional microscope group. Anatomical and functional outcomes were comparable between the two groups. The 3D system exhibited a lower number of indocyanine green injections, shorter epiretinal membrane/internal limiting membrane peeling times, and a reduced incidence of intraoperative retinal hemorrhages, suggesting the 3D visualization system may offer advantages for macular surgery in highly myopic eyes.
