Abstract

This article reports a combined technique of sutureless intrascleral fixated intraocular lens implantation and Descemet membrane endothelial keratoplasty in a patient with anterior pseudophakic bullous keratopathy. Two scleral tunnels were created, corneal incisions were made, and a foldable intraocular lens was cut and removed from the anterior chamber. After performing anterior vitrectomy, a 3-piece foldable intraocular lens was implanted into the anterior chamber. One of the intraocular lens haptics was grasped with a forceps and pulled out from the scleral tunnel. Then, the end of the haptic was cauterized. Similar maneuvers were applied for the other haptic. Next, an 8-mm-diameter donor tissue was prepared, and the recipient endothelial tissue was peeled and removed from the center of the recipient cornea. The prepared donor tissue was injected into the anterior chamber. After proper opening and placement of the donor tissue, an air bubble was injected below the tissue. There were no postoperative complications during the 1-month follow-up.

摘要

本文报道了 1 例采用无缝线巩膜固定型眼内晶状体植入术联合 Descemet 膜内皮角膜移植术治疗前部假性晶状体囊袋下大泡性角膜病变的病例。制作 2 个巩膜隧道,做角膜切口,从前房内切除并取出折叠式人工晶状体。行前段玻璃体切割术后,将 3 件折叠式人工晶状体植入前房。用镊子夹住其中 1 个人工晶状体襻并从巩膜隧道中拉出,然后烧灼襻的末端。对另一个襻重复相同的操作。接下来,准备 1 块 8mm 直径的供体组织,从受体角膜中央剥除并去除内皮组织。将准备好的供体组织注入前房。供体组织适当张开并放置好后,在其下方注入气泡。在 1 个月的随访期间,患者无术后并发症。
