ABiC™ in Alexandria, MN

20 Procedures ( View All )


Your vision is something to celebrate. If glaucoma is keeping you from enjoying your sense of sight or putting a damper on your quality of life, we would like to help you find a solution to curtail elevated intraocular pressure. One way we can do that at Vance Thompson Vision is through ab-interno canaloplasty (ABiC), a minimally invasive glaucoma surgery (also known as MIGS) that can be used to effectively reduce discomfort from elevated eye pressure associated with glaucoma.

Our board-certified ophthalmologist surgeon, Dr. Deborah Ristvedt, is very dedicated to providing glaucoma patients with the most advanced technological options. Vance Thompson Vision employs a team of highly skilled glaucoma surgeons who are leaders in the research and development in all aspects of eye care for the future. Their commitment to surgical and clinical excellence at our Alexandria, MN practice is at the forefront of all treatment planning.

ABiC can approach each aspect of glaucoma, restoring the natural drainage function of the eye, delivering an approximate 30% reduction in eye pressure and reducing the need for glaucoma medications by up to 50%.

Glaucoma FAQs

Best Candidates

Only a board-certified ophthalmologist can determine if ABiC is an option for you. During a consultation at Vance Thompson Vision, we will discuss your eligibility by assessing the presence of the following symptoms, which can help us determine a treatment. The best candidates for ABiC:

  • Have primary open-angle, pseudoexfoliation, or pigmentary glaucoma
  • Are intolerant of glaucoma medications, or have difficulty taking them as prescribed
  • Wish to reduce the number of glaucoma medications they are currently taking
  • Have difficulty committing to regular follow-up treatments
  • Have a history of failed ALT (argon laser trabeculoplasty) treatments

Treatment Options

In our outpatient facility, ABiC treatment begins with a small incision in the eye. A catheter will then be inserted into the drainage canal of the eye. Next, the catheter will be rotated in a circular motion to open up the canal, enlarging it, and easing its ability to drain correctly. Next, the catheter is slowly removed while a viscoelastic gel is injected into the canal for proper dilation. While the canal is being flushed and enlarged, the catheter will be removed from the eye. The fundamental idea is to restore the eye's ability to drain naturally, in turn decreasing the pressure.

What to Expect

Immediately following your ABiC procedure, you may resume normal, day-to-day activities. It is important to remember that the best treatment for glaucoma is consistency so you will need to continue visiting your eye care provider at least every six months. ABiC is associated with very few post-procedure risks, but these may include:

  • Bleeding 
  • Intraocular pressure increases
  • The formation of a bleb (a blister-like or aqueous fluid buildup at the surgical site)
  • Intraocular pressures decreasing too drastically
