摘要

摘要:iStent是一种眼内植入物,位于Schlemm管内,允许房水直接循环至小梁网。它是微创青光眼手术的几种手术之一。因为其在轻度至中度青光眼中降低眼内压的作用以及良好的安全性,微创青光眼手术的突出作用正在增加。经超声青光眼滤过手术的明显并发症可能性增加,包括低血压,脉络膜上腔出血和眼内炎长期风险。相比之下,iStent使这种风险最小化,并且在相关并发症方面与白内障手术相似。如将要讨论的那样,多个文章已经解决了植入物的安全性和功效。本综述还提供了植入技术的概述以及术后期望。展望未来,第二代模型可以轻松植入,并且多个支架的使用可能在更晚期的疾病中发挥作用。

The iStent is an intraocular implant that resides within Schlemm canal and allows for direct bypass of the trabecular meshwork by aqueous fluid. It is one of several procedures termed microinvasive glaucoma surgery. The prominence of microinvasive glaucoma surgery is growing because of its role in lowering intraocular pressure in mild to moderate glaucoma combined with its favorable safety profile. With transcleral glaucoma filtering surgery, there is an increased potential for significant complications including hypotony, suprachoroidal hemorrhage, and long-term risk of endophthalmitis. In comparison, the iStent minimizes this risk and has been shown to be similar to cataract surgery in terms of associated complications. As will be discussed, multiple publications have addressed both the safety and efficacy of the implant. This review additionally presents an overview of implantation technique as well as what to expect postoperatively. Looking forward, the second-generation models may ease implantation and the use of multiple stents may potentially play a role in more advanced disease.
