    How advances in phaco benefit glaucoma surgery


    By itself, phacoemulsification can lower IOP 3 to 5 mm Hg in both chronic open-angle glaucoma (COAG) and pseudoexfoliation and is an important treatment for narrow angle glaucoma, he said.

    How does it work? It's possible that the procedure creates space, but ultrasound may play a role as well, he said.

    Minimally invasive glaucoma surgery (MIGS) combines well with cataract surgery, said Dr. Crandall. One category of MIGS options targets Schlemm's canal. This includes the Glaukos iStent, the Ivantis Hydrus Microstent, the New World Medical Kahook Dual Blade, the Ellex I-Track gonioscopy-assisted transluminal trabeculotomy (GATT), ab-internal canaloplasty and the Sight Sciences Visco360.

    Another category of MIGS targets the subconjunctival space. This includes the Alcon Ex-press, the Allergan Xen Gel Stent, and the Santen InnFocus MircoShunt.
