ABSTRACT
The major indication of viscocanalostomy (combined with phacoemulsification or not) is open-angle glaucoma and the major contraindication is neovascular glaucoma and angleclosure glaucoma. In neovascular glaucoma, the angiofibrous membrane, preventing aqueous flow, cannot be compensated with the dilated Schlemm’s canal. In angle-closure glaucoma, the Schlemm’s canal dilated by viscoelastic material may increase the risk of iris incarceration or cause dysfunction of the filtering of the Descemetic window. It is necessary to perform basal iridectomy or laser iridectomy through a new incision on the patients with angle-closure glaucoma (the angle is not closed completely).13 The author only performs this procedure on patients with primary open-angle glaucoma combined with cataract.
