3D Heads-Up Display vs. Standard Operating Microscope Vitrectomy for Rhegmatogenous Retinal Detachment

Area of Science:

• Ophthalmology
• Surgical Technology
• Retina Surgery

Background:

• Rhegmatogenous retinal detachment (RRD) is a significant cause of vision loss.
• 23-gauge pars plana vitrectomy is a common surgical approach for RRD.
• Advancements in surgical visualization, such as 3D heads-up display (HUD) platforms, are being explored as alternatives to standard operating microscopes (SOM).

Purpose of the Study:

• To compare the efficacy and outcomes of 23-gauge vitreoretinal surgery for RRD using a 3D HUD system versus a traditional SOM.
• To evaluate key metrics including primary retinal reattachment rate, proliferative vitreoretinopathy (PVR) development, best-corrected visual acuity (BCVA), and surgical duration.

Main Methods:

• A retrospective cohort study involving 140 patients with primary RRD.
• Patients underwent 23-gauge pars plana vitrectomy, either with a 3D HUD (NGENUITY) or SOM.
• Phacoemulsification with intraocular lens (IOL) implantation was performed for significant cataracts; minimum follow-up was 2 months.

Main Results:

• No significant differences were observed between the 3D HUD and SOM groups in terms of age, RRD extent, number of retinal tears, macular involvement, or preoperative BCVA.
• Postoperative outcomes were comparable: primary retinal reattachment rates (88.6% vs. 94.3%), PVR development (12.9% vs. 7.1%), and final BCVA (0.26 vs. 0.21 logMAR).
• The 3D HUD group experienced a significantly longer surgical duration initially (66.2 vs. 61.2 min), but this difference diminished after a learning curve of approximately 35 cases.

Conclusions:

• The 3D HUD platform achieves comparable results to conventional SOM for 23-gauge vitreoretinal surgery in RRD patients.
• Key outcomes such as retinal reattachment, PVR incidence, and final BCVA are similar between the two visualization methods.
• An initial learning curve may contribute to slightly longer surgical times with the 3D HUD, but this effect is transient.
