The World Health Organization has endorsed the bilamellar tarsal rotation procedure to correct blinding trachomatous trichiasis. Our field observations of bilamellar tarsal rotation have revealed some significant departures from this procedure as described in the World Health Organization manual. We designed the trachomatous trichiasis clamp to address the shortcomings of the standard instrumentation and to help nonphysicians perform the procedure more safely, reproducibly, and successfully. The trachomatous trichiasis clamp standardizes several aspects of the surgical technique that are not always performed consistently, providing guides for correct clamp and incision placement. A full-thickness eyelid incision can be made and sutures placed in a bloodless field. Two surgical technicians tested the trachomatous trichiasis clamp in 10 patients and found that it was easier to use, shortened surgery time, allowed straighter and more precisely placed incisions, and offered excellent protection for the eye.
世界卫生组织已认可双层睑板旋转手术用于矫正致盲性沙眼性倒睫。我们对双层睑板旋转手术的现场观察发现，该手术与世界卫生组织手册中描述的方法存在一些显著差异。我们设计了沙眼性倒睫夹，以解决标准器械的缺点，并帮助非医生更安全、可重复且成功地实施该手术。沙眼性倒睫夹使手术技术中一些并非总是一致执行的方面标准化，为正确放置夹子和切口提供指导。可以在无血视野下进行全层眼睑切口并放置缝线。两名手术技术员在10名患者身上测试了沙眼性倒睫夹，发现它使用起来更简便，缩短了手术时间，使切口更笔直、放置更精确，并且为眼睛提供了出色的保护。
