With the advent of nonpenetrating glaucoma surgeries (NPGS), these techniques are noticed more considerably by glaucoma surgeons due to lower complications in comparison to penetrating surgeries with comparable outcomes. One of the main objectives in these surgeries is the creation of an intrascleral filtering space as an alternative for subconjunctival filtering bleb. Intrascleral fibrosis in the long term reduces the volume of intrascleral bleb, so the use of implants as a space holder for preventing the collapse of scleral flaps and continued aqueous humor drainage is recommended. A lot of materials with diverse designs have been used as implants in NPGS. In this study, the remaining of Ahmed valve's tube was used as an implant in four eyes of four patients. The technique for the implant we introduced, offers significant advantages over previously reported implants. The material is biocompatible, low cost, and easily accessible in all the centers performing glaucoma surgeries.
随着非穿透性青光眼手术（NPGS）的出现，与具有相似效果的穿透性手术相比，这些技术因并发症较少而受到青光眼外科医生更多的关注。这些手术的主要目标之一是创建一个巩膜内滤过空间，作为结膜下滤过泡的替代方案。长期的巩膜内纤维化会减少巩膜内泡的体积，因此建议使用植入物作为空间支撑物，以防止巩膜瓣塌陷并持续引流房水。许多具有不同设计的材料已被用作NPGS中的植入物。在本研究中，艾哈迈德瓣膜的剩余导管被用作四名患者四只眼睛的植入物。我们介绍的植入技术比先前报道的植入物具有显著优势。该材料具有生物相容性、成本低，并且在所有进行青光眼手术的中心都很容易获得。
