Biometric Changes After Intervention of Anterior Chamber Angle : an Observational Study

The drainage angle in the anterior chamber of the eye mediates the outflow of aqueous humor, and pathological changes here can lead to high intraocular pressure and glaucoma. Minimally invasive glaucoma surgery, particularly angle surgery, has advanced recently, allowing clear visualization of angle structures like the trabecular meshwork and Schlemm's canal using surgical goniolens. Techniques for angle intervention include widening the angle, reopening closed angles, and rebuilding outflow pathways using methods such as laser peripheral iridotomy, Argon laser peripheral iridoplasty, and mechanical separation of adhered tissues. Our research team plans to conduct imaging studies to track the healing of angle tissues post-surgery, aiming to support innovation and standardization of minimally invasive angle surgery.

Swedish Microinvasive Glaucoma Surgery Study (SMIGS)

The purpose of the study is to investigate the efficacy of Cataract Surgery as stand-alone compared to Cataract Surgery in combination with Kahook Dual Blade Glide goniotomy (KDB) or iStent Inject W Trabecular Microbypass Stent (Istent) in eyes with Open-angle glaucoma.

Evaluation of Phacogoniotomy in Medically-controlled POAG

The goal of this multicenter non-inferiority randomized controlled trial is to compare the efficacy of phacoemulsification with intraocular lens implantation (PEI) combined with goniotomy (GT) and PEI combined with medical therapy (MED) in the treatment of medically-controlled primary open-angle glaucoma (POAG) with cataract. The main questions it aims to answer are: * Whether the PEI+GT was non-inferior to PEI+MED with regard to the intraocular pressure lowering effect in medically-controlled POAG. * Whether the PEI+GT has value of health economics. Participants will be randomized to receive either PEI+GT or PEI+MED, and followed up with a 1-year period as a primary outcome.
