Surgery for angle-closure glaucoma: two different approaches compared

This trial is testing two surgical approaches for people with primary angle-closure glaucoma, a serious eye condition where fluid pressure builds up in the eye. One approach combines cataract removal with a procedure to open the drainage angle in your eye (phacoemulsification with goniosynechialysis). The other is a traditional filtration surgery called trabeculectomy, which creates a new drainage pathway. The study will compare how well each surgery controls eye pressure and which one has fewer complications over 12 months.

Angle-closure glaucoma can cause vision loss if not treated, and doctors need better information about which surgery works best. This trial exists to help doctors understand whether combining cataract removal with angle opening is as effective as traditional filtering surgery, especially for patients who already need cataract surgery.
