Comparison of Surgical Performance of Internal Limiting Membrane Peeling Using a 3-D Visualization System With
Background And Objective:
To compare the surgical performance of internal limiting membrane (ILM) peeling in idiopathic macular hole using a digitally assisted vitreoretinal system (DAVS) and an analog microscope (AM).
Patients And Methods:
Patients were operated on using an AM (Group A) and a DAVS (Group B). The data analyzed included surgical time required to complete ILM peeling, number of attempts to create ILM flap and complete ILM peeling, and intraoperative complications.
Results:
Each group included 20 patients. The average surgical time for ILM peeling in groups A and B was 123.05 seconds ± 42.23 seconds and 142.35 seconds ± 31.49 seconds, respectively (P = .109). The mean number of surgical attempts to create the ILM flap was 1.05 ± 0.22 and 1.70 ± 1.22 respectively (P = .008). The mean number of surgical attempts to complete ILM peeling was 22.85 ± 9.95 and 27.20 ± 7.16, respectively (P = .121). Retinal touch occurred in one and three patients, respectively (P = .534).
Conclusions:
DAVS provides similar surgical performance to AM; however, the creation of ILM flap is difficult with DAVS compared to AM. [Ophthalmic Surg Lasers Imaging Retina. 2018;49:941-945.].
