Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Purpose: To analyze the clinical benefits of using the NGENUITY 3D Visualization System in vitreoretinal surgery with low levels of endo-illumination, focusing on functional and structural retinal protection in patients with idiopathic epiretinal membranes (ERM).

Design: Prospective, randomized, comparative study. Methods: Forty pseudophakic patients (29♀, 11♂; age 60-80 years) with ERM underwent 27G pars plana vitrectomy (PPV) and were randomly divided into two groups: Group I (20 eyes, stand-ard microscope \[Hi-R 900\], endo-illumination 3.2 Lm) and Group II (20 eyes, 3D heads-up NGE-NUITY system, endo-illumination 0.5 Lm). Preoperative and 6-month postoperative evaluations included slit-lamp examination, intraocular pressure (IOP, Pascal tonometer), Distance Best Correct-ed Visual Acuity (DBCVA, logMAR), Central Subfield Thickness (CST), Retinal Nerve Fiber Layer Thickness (RNFL, OCT), Pattern ERG (PERG), multifocal ERG (mfERG), flash ERG (ERG, IS-CEV standards), and retinal sensitivity (HFA macula test). Surgery time, xenon light exposure, ERM/ILM peeling time, fundus autofluorescence (FAF), metamorphopsia incidence, and intra-/postoperative adverse events were analyzed. Results were statistically evaluated (p \< 0.05).
