Alcon Pulls CyPass Micro-Stent from Market
Alcon has withdrawn from the market its CyPass Micro-Stent for surgical glaucoma due to safety concerns documented in a five-year study. The COMPASS-XT study showed that at five years, the CyPass Micro-Stent group experienced statistically significant endothelial cell loss compared to the group who underwent cataract surgery alone, an FDA notice says. Alcon advises ophthalmic surgeons to stop implanting the device. The agency approved it in 2016 for use in conjunction with cataract surgery in adult patients with mild-to-moderate primary open-angle glaucoma.
