In this video, we aimed to demonstrate a comparison of various visual parameters between the ORBEYE VOM and the SOM. We also conducted an V-01 10:00 AM Saturday, October 17, 2020 animal study to evaluate the surgical experience and efficacy of the VOM. METHODOLOGY: The depth of field, working distance, and operative NON-INVASIVE SELECTION OF SINGLE SPERM field were compared between the 4K3D OBYEYE VOM (Olympus/Sony) WITH HIGH DNA INTEGRITY FOR and the SOM.
