Ab-interno Canaloplasty (ABiC™) is a comprehensive minimally invasive glaucoma procedure (MIGS) procedure that is a modification of the traditional canaloplasty procedure. ABiC™ can be combined with or done without cataract surgery. It is performed via micro-incisions in the cornea to gain access to the trabecular meshwork outflow pathway. ABiC™ is a restorative MIGS procedure designed to re-establish the eye’s natural outflow drainage system; it accesses, catheterizes, and viscodilates the trabecular meshwork, Schlemm’s canal, and also the distal outflow system, beginning with the collector channels. As with other MIGS, this procedure does not involve opening up the conjunctival tissues. This is a major advantage of this procedure as it makes future glaucoma surgery (if needed) a lot simpler with less risk of failure.

This is an outpatient procedure performed in an ambulatory surgery center. The surgery is usually done under local anesthesia with intravenous sedation. Your doctor will want to examine you in the office the following day and you will be prescribed a regimen of postoperative drops for the next four to six weeks. If the procedure is successful you can expect a decrease in the intraocular pressure and you possibly may come off some of your glaucoma medications. It takes about 6 to 8 weeks before the outcome of the procedure is known.
