Three Cases of Intraoperative Acute Fluid Misdirection Syndrome during Cataract Surgery

ABSTRACT

Purpose@#We report the management of three cases of intraoperative acute fluid misdirection syndrome during cataract surgery.Case summary: Cataract surgery was performed in one eye of an 82-year-old woman with pseudoexfoliation syndrome, one eye of an 80-year-old man with end-stage glaucoma, and both eyes of a 72-year-old man with pseudoexfoliation syndrome. In the first two cases, the capsular bag space decreased during cortex aspiration and after removal of the cortex, respectively. After intravenous mannitol and intake of oral acetazolamide, the intraocular lens was successfully inserted in the first two cases on the same day. In the third case, after first removing the nucleus and cortex of the right eye, the capsular bag space decreased and an intraocular lens was carefully inserted. No intraoperative complications were seen during the left eye operation. One month after the operation, the best-corrected visual acuity had improved and the intraocular pressure was within normal limits for all three cases. @*Conclusions@#A relatively shallow chamber, pseudoexfoliation, zonular laxity, and use of high molecular weight ophthalmic viscosurgical devices may cause acute fluid misdirection syndrome during cataract surgery. Pars plana vitrectomy may be required. However, intravenous high osmotic agent treatment should be attempted first, followed by intraocular lens insertion on the same day.
