Comparison of Phaco Surgery With Goniosynechialysis Versus Trabeculectomy in Glaucoma Treatment
Recruiting now · Not applicable
Conditions studied: Primary Angle Closure Glaucoma
In brief
The goal of this clinical trial is to learn whether phacoemulsification combined with goniosynechialysis (Phaco-GSL) is as effective and safe as trabeculectomy in treating patients with primary angle-closure glaucoma. The main questions it aims to answer are: * Does Phaco-GSL provide similar or better intraocular pressure (IOP) control compared to trabeculectomy? * What are the rates of postoperative complications or adverse events between the two surgical approaches? * How do the two procedures compare in terms of visual acuity recovery and need for glaucoma medications? Researchers will compare Phaco-GSL to trabeculectomy to determine which procedure offers better overall outcomes for patients with angle-closure glaucoma. Participants will: Be randomly assigned to undergo either Phaco-GSL or trabeculectomy Attend scheduled follow-up visits at regular intervals (e.g., 1 week, 1 month, 3 months, 6 months, 12 months) for eye exams and pressure checks
