The most frequent early postoperative complication in the PC group was hyphema, which was observed in 17 eyes (46%) and microhyphema noted in 10 eyes (27%).

Other sequelae of trauma such as zonular dialysis, microhyphema
, and elevated intraocular pressure must be identified as they may complicate treatment.
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
The most frequent postoperative complications associated with canaloplasty include hyphema or microhyphema
, cataract formation, IOP spikes, and hypotony .
Postoperative complications included microhyphema (only observed by gonioscopy) in 3 eyes and mild hyphema in 1 eye, all of which resolved without intervention by the 1-month visit; transient IOP elevation of 32 mmHg on the next day following the surgery in 1 eye, which resolved spontaneously; peripheral anterior synechiae (PAS) in 4 eyes, which was treated with argon laser gonioplasty (LGP); and occlusion by the iris, which occurred in 2 eyes of the LGPtreated eyes with PAS by the 1-month visit and in 1 eye of the LGP-treated eyes with PAS at the 2-month visit (Table 1, Figure 3(b)).
