Detachment of Descemet's membrane is an unusual cause of postoperative corneal edema. The typical detachment is small and usually limited to the area near the limbal wound. These peripheral detachments usually heal without sequelae as endothelium spreads over the area and secretes a new Descemet's membrane. We report an unusual case of spontaneous, extensive central separation of Descemet's membrane occurring 3 weeks following uncomplicated extracapsular cataract extraction with posterior chamber lens implant. Attempted reattachment of the membrane with intracameral air was only partially successful, but 12 weeks later the detachment spontaneously resolved with recovery of vision to 20/30. An anatomic predisposition may be implicated, because the fellow eye exhibits the diffuse thickening of Descemet's membrane. Descemet's detachment is a rare but potentially reversible cause of corneal edema following cataract surgery and should not be confused with early-onset pseudophakic bullous keratopathy.
后弹力层脱离是术后角膜水肿的一种不常见原因。典型的脱离范围较小，通常局限于角膜缘伤口附近区域。这些周边部脱离通常可自愈，不会留下后遗症，因为内皮细胞会覆盖该区域并分泌新的后弹力层。我们报告了一例不寻常的病例，在无并发症的白内障囊外摘除联合后房型人工晶状体植入术后3周，发生了自发性、广泛的中央部后弹力层分离。试图通过前房内注入空气使后弹力层重新附着仅取得部分成功，但12周后脱离自发消退，视力恢复至20/30。可能存在解剖学上的易患因素，因为对侧眼表现出后弹力层弥漫性增厚。后弹力层脱离是白内障手术后角膜水肿的一种罕见但可能可逆的原因，不应与早期人工晶状体性大泡性角膜病变相混淆。
