<qa>  What is the primary outcome of the study?The purpose of this study is to prospectively compare clinical outcomes using straight, one-stage perpendicular versus angled, two-stage trocar insertion during 27 gauge minimally invasive vitrectomy surgery MIVS. The design of the study will be a randomized, clinical trial. Primary outcomes will be sclerotomy suture rates and incidence of suture blebs at the end of 27 gauge MIVS surgery for epiretinal membrane and macular pucker indications no air or gas tamponade. Secondary endpoints will include rate of postoperative wound-related complications such as hypotony, choroidal detachments, endophthalmitis, and sclerotomy-related retinal tears with a minimum of 30 days follow-up.
