The induction of posterior vitreous detachment (PVD) is a fundamental step in most vitreoretinal surgeries. Although in most of the cases, it can be easily performed, there are cases in which the hyaloid is strongly adherent due to the young age of the patients, and simple aspiration without a support by a particular method can cause a waste of time. To reduce the time of surgery and the variability of the cases, a standardized, repeatable, and easily applicable approach is needed. Various surgical techniques have already been described. Some authors described the approaches starting from the Weiss ring separation [The induction of PVD to facilitate the passage of fluids into the sub-hyaloid space is done using different instruments, such as intravitreal diathermy [
