Abstract

We present a surgical technique for evacuating an intracorneal pre-Descemet hematoma that occurred during a canaloplasty procedure. The technique allows both evacuation of the hematoma outside the anterior chamber and preservation of the intact Descemet membrane, and it can be performed within the primary procedure. Intraoperative pre-Descemet hematoma is reported to be a relatively rare complication of canaloplasty; however, to hasten visual recovery and to avoid potentially sight-threatening complications, surgeons should be aware of this possible complication and be prepared to resolve it as early as possible, even within the canaloplasty procedure.

摘要

我们介绍一种用于清除在房角成形术过程中发生的角膜后弹力层前血肿的手术技术。该技术既能将血肿从前房外清除，又能保留完整的后弹力层，且可在初次手术过程中完成。据报道，术中角膜后弹力层前血肿是房角成形术相对少见的并发症；然而，为加速视力恢复并避免潜在的视力威胁性并发症，外科医生应了解这种可能的并发症，并准备好尽早解决它，甚至在房角成形术过程中解决。
