Making Sclerotomy Ports during a Vitreoretinal Surgery: Tips, Tricks and Concerns
The advancement of vitreous surgery from the 20-gauge (20G) era to the present day Transconjunctival Sutureless Vitrectomy (TVS) has favorably transformed patient outcomes in the surgical management of retinal diseases. The 20G system (O’Malley and Heintz, 1974) has been the gold standard technique in modern vitreous surgery for nearly three decades, beginning from the earliest 17G vitrectomy as introduced by Machemer in 1971. The 20G systems were associated with sutured port closure, longer and irregular wound healing, higher vitreous turbulence, greater incidence of port-related complications like retinal breaks, and a longer surgical time. On the other hand, the trochar and cannula based micro incision vitrectomy surgery (MIVS) are associated with early post-operative recovery, better and uniform wound healing, lesser port related complications, lesser vitreous turbulence and increased patient comfort with earlier visual recovery. As with any surgical procedure, the decision and pla
