The Xen Gel Stent lowers intraocular pressure by shunting aqueous humor to the subconjunctival space. While published studies include both open conjunctiva and closed conjunctiva approaches, most publications feature a closed conjunctiva, ab interno approach. While this approach is widely used, other approaches may be preferred for some patients. This paper provides details on surgical steps and tips for enhancing outcomes for an open conjunctiva technique for the implantation of the Xen Gel Stent, as well as reasoning as to when this approach should be used.
Xen 凝胶支架通过将房水引流到结膜下空间来降低眼内压。虽然已发表的研究包括开放结膜和闭合结膜两种入路，但大多数出版物都以闭合结膜、经内路（ab interno approach）为特色。虽然这种方法应用广泛，但对于某些患者，其他方法可能更受欢迎。本文详细介绍了用于 Xen 凝胶支架植入的开放结膜技术的手术步骤和提高手术效果的技巧，以及何时应采用这种方法的理由。
