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.

"My husband was referred by his eye doctor in Helena and we were pleased to get an appointment within a few days. The appointment was a pleasant experience, with friendly, knowledgeable staff. Kacie did the preliminary tests and was very good to my husband and very professional on her knowledge. Dr Swan has a very easy manner and was very thorough and really informative. He spent plenty of time explaining and was clear about the benefits and drawbacks to my husbands procedure. The whole appointment was very relaxed and informative.

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.
