💬In plain words
What the trial is, and whether it could suit you
The goal of this clinical trial is to evaluate the comparative efficacy and safety of Hydrus Microstent, incisional goniotomy, and excisional goniotomy when combined with cataract surgery in patients with mild and moderate open-angle glaucoma. The main questions it aims to answer are:
* How do the intraocular pressure lowering effects of these three microinvasive glaucoma surgeries compare?
* How do the safety profiles of these three microinvasive glaucoma surgeries compare?
Participants will be randomized to one of these three microinvasive glaucoma surgeries in combination with cataract surgery.
