About the iStent

MIGS (minimally invasive glaucoma surgery) has revolutionized eye surgeons' ability to decrease intraocular pressure and ease the symptoms of glaucoma. With the remarkable iStent Micro-Bypass device, the experienced ophthalmologist surgeons at Vance Thompson Vision can significantly lower eye pressure by enabling built-up fluid to drain naturally from the eye. Approved by the FDA in 2012, the iStent is the world's smallest implantable medical device and works by creating a pathway for drainage in the trabecular meshwork of the eye.

At Vance Thompson Vision, Drs. Swan, Berdahl, Greenwood, Baartman, and Ristvedt perform extremely thorough exams and tests to ensure that every glaucoma patient receives the ideal treatment for their personal case. The iStent has undergone more study than any other glaucoma procedure device currently available, and the doctors at Vance Thompson Vision are proud to offer it as one potential option for optimal results. Contact our Billings, MT facility for a consultation to get more information about MIGS procedures and the iStent.

Glaucoma FAQs

Best Candidates

The iStent implant is designed for patients who have both glaucoma and cataracts. However, those with mild or moderate open-angle glaucoma typically receive the best results. To learn whether the iStent is ideal for you, you will need to visit us for a thorough consultation and evaluation with a member of our doctor team. During your consultation, we will need to review your medical history, your family's medical history, and any medications you are currently taking.

Treatment Options

Most commonly performed at the same time as cataract surgery, the iStent implantation is performed as an outpatient procedure at Vance Thompson Vision. Your eyes will be fully numbed, and you maybe be given a mild sedative; therefore, you will need to make sure to bring along an adult who can drive you home afterward.

For patients having simultaneous cataract removal and iStent implantation, our surgeons use the same tiny incision for both procedures. The iStent is only 1mm by .33mm and is injected into the trabecular meshwork with a specialized tiny device. Its placement in the trabecular meshwork aids the aqueous flow in the eye and lowers intraocular pressure. This can decrease a patient’s dependency on glaucoma eye drops and other medications.

What to Expect

You will need to take a few prescription medications in the weeks after your surgery, and we may require that you have them filled prior to having the surgery done. These will be medications to help with eye inflammation and to prevent infection. Dr. Swan or someone on his team will explain your post-surgery home-care instructions, which must be followed very carefully. It is also vital that you schedule and attend follow-up appointments at Vance Thompson Vision so that we can monitor your eye pressure and make any necessary adjustments to your treatment. We encourage you to call us with any questions you may have regarding your aftercare in the weeks following your procedure.
