A theoretical problem with bypass of the meshwork is blood reflux from Schlemm's canal into the anterior chamber via the tube, creating a microhyphema.
Canaloplasty can also be successfully performed in patients with failed trabeculectomy in which Schlemm's canal has been left undamaged from previous filtrating surgeries [16].
This may be explained by prevention of postoperative hemorrhage or fibroblastic proliferation, non-traumatic cannulation of the Schlemm's canal after viscodilation and viscodissection with viscoelastic material, keeping away the lips of the trabeculotomy incision, and prevention of anterior chamber shallowing, which play important roles in decreasing the anterior chamber inflammation and retarding the woundhealing process.

Based on these molecular findings, the team are now working to develop eye drops which would activate the regrowth of the clogged Schlemm's canal in models of the condition, in order to lower IOP.
The protocol allowed for previous surgeries that would not interfere with complete circumferential catheterization of Schlemm's canal.
They also have a direct action by binding to receptors present on endothelial cells in Schlemm's canal, causing relaxation of intracellular tight junctions that eases the resistance to outflow.
