Comparative Efficacy of Phacoemulsification Combined with KDB Goniotomy versus Trabeculectomy for Primary Angle-Closure Glaucoma: A Retrospective Cohort Study

Both KDB goniotomy and trabeculectomy, when combined with phacoemulsification, effectively improve visual acuity, reduce IOP, and stabilize VF in patients with moderate-to-severe PACG and concurrent cataract. Phaco-KDB is an effective <i>ab interno</i> procedure that achieves comparable success rate to phaco-trab, it's minimally invasive nature may delay or obviate filtration surgery, simplify procedure, and offer faster visual rehabilitation.
