Stegmann canal expander helps lower IOP in patients with primary open-angle glaucoma
The Stegmann canal expander, implanted during canaloplasty, lowered IOP and reduced complications in patients with primary open-angle glaucoma, according to a study. The prospective, single-center noncomparative study included 22 eyes of 22 consecutive patients with medically uncontrolled primary open-angle glaucoma who underwent primary viscocanalostomy and implantation of the new canal expander. The expander was implanted into Schlemm’s canal, and patient follow-up time was at least 1 year.
