Effect of adjunctive viscogonioplasty on drainage angle status in cataract surgery: a randomized clinical trial

Abstract

Both Phaco alone and Phaco-VGP resulted in widening of the drainage angle, deepening of the anterior chamber and reduction of intraocular pressure (IOP) and PAS extent in PACG eyes. Phaco-VGP resulted in significantly more reduction of PAS. However, it seems that additional VGP has no significant effect on short-term IOP.
