Hybrid MIGS Technique: Dual Blade Goniotomy and Direct Viscodilation of the Collector Channels with Cataract Surgery: 18 Months Results
After cataract surgery, the Dual Blade removed 180° of trabecular meshwork. Viscoelastic was injected into the exposed ostium of the Collector Channels as the perpendicular viscoelastic cannula was held firmly against the outer wall and dragged through the gutted canal. Moderate to severe glaucoma comprised 50% of the 120 eyes at 1 year. 33% had previous glaucoma surgery. 80% were African American. 50% were diabetics. 50% were on an anticoagulant.
The synergy of Goniotomy and Viscodilation markedly reduces drops even in advanced glaucoma with 46% of eyes achieving an IOP ≤15mm Hg, thus improving compliance and reducing the associated financial burden. The Goniotomy-Viscodilation-Cataract technique addresses both trabecular outflow resistance and salvages the collapsed collector channels.
