About the iStent
Minimally invasive glaucoma surgery, known as MIGS, has changed the way eye surgeons restore a patient's vision. By creating a pathway through the eye, our experienced ophthalmologist surgeons at Vance Thompson Vision can implant an iStent Micro-Bypass device to aid in draining aqueous fluid naturally from the eye. The trabecular stent, iStent, is the smallest medical device ever implanted into humans to decrease eye pressure by creating a pathway in the high-resistance portion of the eye’s drainage system. The iStent was the first trabecular micro-bypass device approved by the FDA (summer 2012) and is the most thoroughly studied glaucoma device on the market today. At Vance Thompson Vision, Drs. Berdahl, Greenwood, and Swan take great care to select the right treatment for each glaucoma patient to lower intraocular pressure through comprehensive eye exams and testing. Learn more about MIGS and discover if iStent is the right choice for you.
"I had a PRK surgery done here and had THE best experience! Every staff member is extremely caring, professional, and knowledgeable and they go above and beyond! Dr. Swan texted me the night after my surgery to make sure I was doing ok and answered my questions. They have been very good about working with me as I don’t live in Bozeman and had to travel for my appointments and surgery. When you choose Vance Thompson Vision, you are choosing the best care! Highly recommend!"- K.C. / Google / Aug 23, 2019
"Dr swan, Kim, Susan and others were all amazing. Superior friendly & knowledgeable staff. Took me through the whole process guiding, answering any questions or concerns. Dr Swan put me right at ease from the moment he entered the exam room, greeted me with a firm handshake and welcoming smile. I was nervous about having cataract surgery because I hate anything in my eyes. Everyone assured me they would make me comfortable and they did. I couldn't be any happier with the results. For the first time in nearly 60 years I can see without glasses."- J.R. / Google / Aug 22, 2019

"I always knew that Vance Thompson VISION was a world class group of physicians and wonderful staff! On my recent check up in talking with the staff we were visiting and I found out she had been a vet tech before so the conversation went from there and that I had recently lost my sweet dog. And a day later I receive these gorgeous flowers! I’ve never known such a truly caring group 🙏I Will never forget your thoughtful deed🐾🌈"- R.K. / Facebook / Jul 27, 2019
If you have been diagnosed with glaucoma (with or without cataracts), Drs. Berdahl, Greenwood, or Swan can make the determination if you are a great candidate for the iStent implant. We advise you to make an appointment for a consultation. Be prepared to review your list of current medications and answer a few questions regarding your medical and family health history.
Generally implanted during cataract surgery, the iStent implantation is an outpatient surgery performed at our Bozeman office at Vance Thompson Vision. Our team will prep you for surgery with anesthetic (numbing) eyedrops and a mild sedative if necessary. You will need to arrange for a ride home prior to surgery.
If you are also having a cataract excision, there will be no need for additional incisions to insert the implant. Measuring only 1mm by .33mm, the iStent is inserted into the trabecular meshwork of the eye (Schlemm's canal). When inserted into the eye, the small tube has been shown to increase the aqueous flow in the eye, which decreases the pressure within the eye and can decrease a patient’s reliance on glaucoma medication.
What to Expect
You can expect to have a few prescriptions to fill after your surgery to prevent infection and inflammation in your eyes. It is very important to follow all your post-surgical instructions from Drs. Berdahl, Greenwood, or Swan, and attend all follow-up appointments with your eye care provider. We will chart your intraocular pressure and make adjustments to your treatment as needed. If you have concerns or questions about iStent aftercare, we would be happy to assist you.
