“…Accordingly, stent implantation through MIGS should be an effective method of treating POAG, as its IOP-lowering effect is based on bypassing this crucial site of AH outflow resistance. This is supported by the above mentioned studies: IOP is reduced on average by 10-26% by the iStent Ò (Spiegel et al 2009;Seiboldet al 2016), up to 40% by the Hydrus Ò (Otarola et al 2020), and 29-42% with the Xen Ò (De Gregorio et al 2018); the PRESERFLO Ò Micro-Shunt is even better, averaging 30-55%. These studies differ widely in reported results and evidence.…”

The aim of this article is to discuss how physiology and anatomical background affect the effectiveness of implant-dependent microinvasive glaucoma surgery (MIGS). First, we provide a micro view of aqueous outflow and tissue behaviour. Second, we review studies exploring the mechanisms of the pressure-lowering effect of MIGS, as well as tissue behaviour during aqueous flow and tissue motion. We also describe and classify microinvasive surgical procedures and the most important types of implants, as well as their mechanisms of action, implantation techniques and efficacy. Further, we summarize the indications and surgical results presented in recent studies, providing an evidence-based update on novel and emerging MIGS techniques for the treatment of open-angle glaucoma. These data can help surgeons to personalize the management of glaucoma and to choose the best MIGS option for individual glaucoma patients.

“…At 1 year, more HMS had complete success (p < 0.001) and more were medication-free (difference = 22.6%, p = 0.0057). 168,169 Compared to ab externo canaloplasty, HMS performed similarly over 2 years. 170 The most common adverse finding was nonobstructive (14.9%) and obstructive (3.8%) PAS.…”

After a long period of little change, glaucoma surgery has experienced a dramatic rise in the number of possible procedures in the last two decades. Glaucoma filtering surgeries with mitomycin C and glaucoma drainage devices remain the standard of surgical care. Other newer surgeries, some of which are minimally or microinvasive glaucoma surgeries, target existing trabecular outflow, enhance suprachoroidal outflow, create subconjunctival blebs, or reduce aqueous production. Some require the implantation of a device such as the iStent, Hydrus, Ex-PRESS, XEN and PRESERFLO, whilst others do not-Trabectome, Kahook dual blade, Ab interno canaloplasty, gonioscopy-assisted transluminal trabeculotomy, OMNI and excimer laser trabeculotomy. Others are a less destructive variation of an established procedure, such as micropulse transscleral cyclophotocoagulation, endoscopic cyclophotocoagulation and ultrasound cycloplasty. Cataract surgery alone can be a significant glaucoma operation. These older and newer glaucoma surgeries, their mechanism of action, efficacy and complications are the subject of this review.
