To describe a new technique for harvesting a lamellar graft from a corneoscleral button in the absence of an artificial anterior chamber.
Two layers of sterile fine-weave fabric were wrapped tightly around a glass orbital implant. The corneoscleral button was sutured firmly at its scleral rim onto the fabric. The lamellar graft then was dissected in the regular fashion.
The lamellar graft was successfully obtained. During the dissection, the donor cornea and its supporting fabric-covered glass ball were easily handled, and there was minimal risk of perforation of the posterior lamella of the donor cornea.
This simple technique allows a lamellar graft to be easily obtained from a corneoscleral button without specialized and expensive equipment.
描述一种在没有人工前房的情况下从角膜巩膜纽扣上获取板层移植物的新技术。
将两层无菌细织物紧紧包裹在玻璃眼眶植入物周围。将角膜巩膜纽扣在其巩膜边缘牢固地缝合到织物上。然后以常规方式解剖板层移植物。
成功获得板层移植物。在解剖过程中,供体角膜及其支撑的织物覆盖的玻璃球易于操作,供体角膜后板层穿孔的风险极小。
这种简单的技术无需专门且昂贵的设备就能轻松从角膜巩膜纽扣上获取板层移植物。
