Efficacy and Safety of iStent Inject and Inject W in the Management of Primary Open-angle Glaucoma

Recruiting

• Conditions: MIGS; POAG

• Registration Number: NCT05062668
• Lead Sponsor: Centre Hospitalier Universitaire, Amiens

Brief Summary

Primary open-angle glaucoma (POAG) is a chronic eye disease in which the only validated treatment is to lower intraocular pressure (IOP). It is the 2nd leading cause of blindness worldwide. The iStent® inject and inject W is an implantable device that is part of a new entity of so-called minimally invasive glaucoma surgery whose goal is to lower IOP with minimal tissue disruption in order to avoid the complications of conventional glaucoma surgery. This surgery is used in conjunction with cataract surgery in France. The primary objective is to study the 1-year efficacy and safety of combined cataract and iStent inject and inject W in the management of POAG in an observational, retrospective, controlled study of a cohort of POAG patients undergoing cataract surgery only.
