SAN FRANCISCO — Implanting the Trabectome device either alone or combined with cataract surgery can offer a minimally invasive option for controlling IOP in patients with open-angle glaucoma, according to a surgeon speaking here.

Don S. Minckler, MD, and colleagues evaluated their results for about 204 procedures, all of which were done in open-angle glaucoma patients except for two. The Trabectome (NeoMedix) implantation was combined with phacoemulsification in 42 cases, according to Dr. Minckler, who presented the study results at the American Glaucoma Society's annual meeting.

"We think this procedure deserves serious consideration for a variety of reasons, most of all because it fits into the therapy spectrum before trabeculectomy, laser trabeculoplasty or medication in some patients," he said.

Overall, preoperative IOP averaged 25.2 ± 7.4 mm Hg, which decreased 42% to average 17 ± 4.1 mm Hg at 36 months follow-up and decreased 47% to average 16.7 ± 2.6 mm Hg at 1 year, Dr. Minckler said.

Complications included back bleeding in all patients, which cleared after several days. There were no long-term complications, although nine eyes required trabeculectomy and three eyes required shunt installation, he said.
