Gel Stent Versus Trabeculectomy: The Randomized, Multicenter, Gold-Standard Pathway Study (GPS) of Effectiveness and Safety at 12 Months.

At month 12, the gel stent was statistically noninferior to trabeculectomy, per the percentage of patients achieving ≥20% IOP reduction from baseline without medication increase, clinical hypotony, vision loss to counting fingers, or SSI.

One-Year Real-World Outcomes of Ab-Externo Gel Stent Placement From the EXPAND Study.

Ab-externo GS placement effectively lowered IOP and the medication count without unexpected complications/AEs, expanding implantation options based on patients' needs and surgeons' preferences.
