Objective Quantification of Depth-of-Field Advantage in 3D Surgical Video System for Vitreoretinal Surgery: Safety and Efficacy in Macular Diseases

Abstract

Purpose: The objective of this study is to demonstrate, based on objective clinical indicators, the advantages of depth of field provided by the 3D surgical video system compared to the traditional microscope during vitrectomy for treating epiretinal membranes（ERM) or macular holes(MH). Methods: A total of 38 patients were included in this study and randomly assigned to either the 3D surgical video group or the conventional microscope group. Surgical parameters such as the Focal plane adjustment frequency (FPAF), membrane peeling time, and number of attempts to peel the membrane were recorded for each patient. Additionally, patients were followed up for 3 months postoperatively. Results: No significant differences in age, gender, operated eyes, or follow-up rates between the groups. The 3D group had significantly lower Focal Plane Adjustment Frequency (FPAF) in macular hole surgery and epiretinal membrane surgery . No significant differences in peeling maneuvers, time, or total surgical time. Postoperative follow-up data showed no significant differences. Conclusion: In conclusion,the 3D surgical video system exhibits potential advantages in depth of field.The 3D surgical video system is a safe and effective technology in vitrectomy for macular diseases.
