About ABiC

Ab-interno canaloplasty (ABiC) is a minimally invasive glaucoma surgery (MIGS) that can potentially reduce the symptoms of glaucoma, slow or prevent damage to the optic nerve, and decrease dependence on glaucoma medications. 

Good vision and healthy eyes play a vital role in a person's quality of life. If glaucoma is affecting your sight or limiting your daily activities, the outstanding ophthalmic surgical team at Vance Thompson is here to help you find the ideal way to manage your condition. One of the many advanced MIGS procedures performed by board-certified ophthalmologist surgeon Dr. Russell Swan and his team is the ABiC. This innovative treatment addresses glaucoma by enhancing the function of the Schlemm's Canal, an important part of the eye's natural drainage system. Studies have shown that the ABiC can reduce eye pressure by up to 30% and, in many patients, can decrease required glaucoma medications by 50%.

Contact Vance Thompson Vision in Billings, MT to schedule a consultation to learn more about the ABiC and other MIGS procedures.

Glaucoma FAQs

Best Candidates

If you are interested in finding out if you are a candidate for ABiC or another MIGS, you will need to visit Vance Thompson Vision for a consultation with a board-certified ophthalmologist. During your consultation, your doctor will perform an eye exam, talk with you about your eye health and general health, vision goals, and lifestyle, and give you recommendations for your ideal treatment options. In general, the patients most eligible for ABiC:

  • Have been diagnosed with primary open-angle, pseudoexfoliation, or pigmentary glaucoma
  • Have not had success with or are intolerant of glaucoma medications
  • Have difficulty taking glaucoma medications as directed
  • Want to decrease the number of glaucoma medications they are currently taking
  • Have had previous unsuccessful ALT (argon laser trabeculoplasty) treatments

Treatment Options

ABiC is an outpatient procedure performed on site at our facility. Before the treatment begins, the eye or eyes will be fully numbed. Then the surgeon will create a very tiny incision, through which a microcatheter will be carefully inserted into the Schlemm's Canal, the natural drainage canal of the eye. This microcatheter will pass along the full extent of the canal, which helps to enlarge it. As the microcatheter is carefully pulled back out, it injects tiny amounts of specialized viscoelastic gel into the space, helping to keep the canal properly dilated after the procedure. Widening the space within the canal increases the eye's ability to drain via its natural structures so that internal eye pressure is lowered.

What to Expect

The vast majority of patients are able to resume their routine activities immediately following the ABiC procedure. However, it is vital that you attend all of your follow-up appointments and visit your primary eye care provider twice per year. The most important aspects of any glaucoma treatment and management plan are monitoring and consistency.

Post-surgery risks related to the ABiC are very rare but can include:

  • Bleeding 
  • Increases in intraocular pressure
  • Drastic decreases in intraocular pressure
  • Bleb formation (a blister-like fluid buildup at the incision site)
