Brief summary

Purpose: Characterize changes in intraocular pressure (IOP), IOP-lowering medications, and visual acuity (VA) through 3 years in patients undergoing combined phacoemulsification and excisional goniotomy with the Kahook Dual Blade (phaco-KDB), with simultaneous goniosynechialysis in cases of angle-closure glaucoma, by a single surgeon (A.H.) in King Fahd Hospital of the University, Dammam, Saudi Arabia. Methods: Prospective, non-comparative, uncontrolled, non-randomized interventional case series. Consecutive patients with medically-treated glaucoma and visually-significant cataract underwent combined surgery. Subgroup analysis of glaucoma subtypes was performed.

Secondary

Measure	Time frame	Description
Visual acuity	36 months	Characterize visual acuity (VA) using logMAR chart, each visit in clinic post undergoing combined phacoemulsification and excisional goniotomy with the kahook dual blade.
