Official Title  ICMJE Not Provided
Brief Summary Small-incision vitrectomy techniques have become increasingly popular, with a number of advantages over the older 20-gauge instrumentation. The beveled wounds created by the 23- and 25-gauge trocar systems theoretically do not require sutured closure. However, a certain fraction of cases, 1% for 25-gauge systems, and 4-38% for 23-gauge systems, do require suture placement. Poor wound closure puts the patient at increased risk of post-operative hypotony and is associated with increased risk of endophthalmitis. Currently, surgeons are divided as to which suture is the best for sclerotomy closure. The current standard of care is 8-0 polyglactin 910 (Vicryl, Ethicon, Cincinnati, OH). This suture is soft and easy to work with; however, it triggers a robust inflammatory response. The alternative is 6-0 plain gut suture, which is more difficult to manipulate and thicker, but causes less tissue inflammation1. The purpose of this study is to prospectively evaluate these two options for sclerotomy closure. The results of this study will enable us to minimize patients' post-operative discomfort while maximizing safety outcomes.
