Journal of Cataract & Refractive Surgery: May 1997 - Volume 23 - Issue 4 - p 476-479 doi: 10.1016/S0886-3350(97)80202-7 Free Metrics Abstract We describe a method in which constant infusion inflow through an anterior chamber maintainer (ACM) is used to maintain positive intraocular pressure (IOP) during cataract extraction through a self-sealing tunnel incision. A retrospective review of patient records showed that the difference in the incidence of intraoperative suprachoroidal hemorrhage was significantly greater in eyes in which IOP was not constant throughout surgery than in eyes in which IOP was maintained using the ACM system. © Williams & Wilkins 1997.
