Combined Phacoemulsification With iStent Inject W Versus Hydrus for Mild to Moderate Open Angle Glaucoma
Stopped early · Not applicable
Conditions studied: Open Angle Glaucoma
In brief
The goal of the study is to prospectively evaluate and compare Hydrus microstent to the iStent Inject Wide in combination with cataract surgery in patients with mild to moderate open angle glaucoma. Hydrus and iStent are the two FDA approved trabecular meshwork targeting microstents to treat open angle glaucoma in conjunction with cataract surgery.
