N2 - Purpose: To report a 25-gauge trocar-cannula that enhances wound closure and reduces the incidence of postoperative hypotony. Design: Development of surgical instruments. Methods: A 25-gauge cannula with a microvitreoretinal (MVR) blade trocar was constructed. The resistance of inserting this trocar cannula was compared with that of the conventional 25-gauge trocar cannula (Alcon Laboratories; Fort Worth, Texas, USA). Vitreous surgery was performed on 55 eyes with the trocar cannula with an oblique sclerotomy incision, and the results were compared with those from 68 eyes that underwent surgery with the conventional trocar cannula. Results: The resistance of inserting the trocar cannula was less than that with the conventional trocar cannula. A temporary hypotony (intraocular pressure [IOP] <6 mm Hg) was found in one eye (2%) with the trocar cannula and in 12 eyes (18%) with the conventional trocar cannula (P = .006, Fisher exact probability test). Conclusions: The trocar cannula with a MVR blade was effective in postoperative wound closure and prevention of postoperative hypotony.
