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.
"Amazing team , Bozeman is lucky to have Dr. Swan and his team. Extremely thorough, detailed and it’s obvious the level of expertise and technology is second to none."- M.B. / Google / Feb 28, 2019
"The staff was amazing from the first phone call to surgery day. If you are considering laser eye surgery you don't need to look further: this is world class technology and customer service right in Bozeman. I had PRK on 1/24/19 with Dr. Swan which was a painless, simple and quick procedure (despite my fears of it). I had -5.25 with astigmatism in both eyes and could tell the vision improvement the same day, drove 5 days later and one week out had major improvement in vision. My aftercare doctor has mentioned how smooth my eyes are and how well they are healing due to Dr Swan's technique. [Tips for PRK: plan to spend 2-3 days relaxing in a dark room (audio books and black out curtains a must!), pain happens after surgery so take the Tylenol immediately to keep up on pain management, and keep up on the eyes drops]"- J.W. / Google / Feb 14, 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.
