Placing the Xen45 gel stent using an ab externo technique helped lower IOP in patients with glaucoma, according to a study.
For more than 10 years, the Xen45 gel stent (Allergan) has been approved for ab interno implantation. However, in her presentation at the virtual Association for Research in Vision and Ophthalmology meeting, Natasha N. Kolomeyer, MD, said a new technique has emerged in recent years.
“In the last 2 years, a novel ab externo approach has been adopted by many surgeons to implant the gel stent, therefore going outside-in instead of inside-out,” she said.
