Abstract: Glaucoma surgery is divided into two major categories: reducing the formation of aqueous humor and increasing the flow of aqueous humor. The former one is represented by the laser ablation of the ciliary processes, and the latter one is represented by trabeculectomy. From traditional glaucoma filtering surgery to newer glaucoma procedures, which target different aqueous outflow pathways, the use of glaucoma drainage implants has improved the safety profile of glaucoma surgery and decreased the complications during the operation and post operation, also the surgical techniques have been getting easier than ever. This article systematically reviews the clinical progress of new glaucoma drainage implants including the implants targeting the trabecular network and schlemm’s canal (iStent, Hydrus Micro-stent)，the implants targeting the superachoridial space (CyPass Micro-Stent, iStent Supra) and the implants targeting the subconjunctival space (XEN gel stent，InnFocus MicroShunt).

Key words: glaucoma, glaucoma drainage implants, trabecular meshwork, superachoridial space, subconjunctival space
