After cataract extraction in our patient, a free fragment of Descemet's membrane from the wound edge became adherent to the central cornea and resulted in persistent corneal edema. With the use of sodium hyaluronate the membrane was successfully removed and visual acuity was restored.
Report of a Case.
—A 66-year-old woman had extracapsular cataract extraction with posterior chamber intraocular lens implantation in the right eye on August 14, 1986. There were no complications during surgery. On the first postoperative day visual acuity in the right eye was counting fingers at 30 cm. There was 3+ microcystic corneal edema, the anterior chamber had 2+ cells and flare, and the intraocular pressure was 38 mm Hg. One drop each of prednisone acetate (1%) four times daily, gentamicin sulfate four times daily, 1% tropicamide every day, and 0.5% timolol maleate twice a day were administered. The intraocular pressure decreased to 22 mm Hg
