About the iStent
Glaucoma is an eye disease that can seriously damage the optic nerve. This is usually the result of abnormally high intraocular pressure caused by the eye's reduced ability to properly drain out fluid. When left untreated, complete blindness can occur. Thankfully, MIGS (minimally invasive glaucoma surgery) has transformed surgeons' ability to treat glaucoma and preserve a patient's vision. With the exceptional iStent Micro-Bypass device, board-certified ophthalmologist Dr. Ralph Chu can safely and effectively lower intraocular pressure.
The iStent is a one-millimeter long titanium device, currently the smallest known medical implant approved by the FDA. It is precisely placed into the eye to create a new channel in the trabecular meshwork so fluid can naturally drain out of the eye, helping to efficiently lower a patient's eye pressure. For numerous patients, this has reduced or eliminated the need for glaucoma management medications. Chu Vision Institute is proud to offer this revolutionary method as a potential solution to produce the best possible outcomes. Reach out to us in Bloomington, MN to schedule a consultation, and learn more about this treatment for managing glaucoma.
"This staff is absolutely amazing!!! They talk to you as a human and take the time to explain what they are going to do. They spend time answering questions and concerns. Dr. Chu and his team…I honestly couldn’t have asked for more. They genuinely care, and you can hear it in their voices. I was nervous, and as an adult male that can be….belittling…but they were amazing! They actually pumped up my confidence. I will never go anywhere else for my eyes. I plan on scheduling all my appointments with them. Give them a chance, they will not disappoint. I heard it in the waiting room, everyone was happy and appreciative. Thank you all for making my life better!"- B.J. / Google / Jun 10, 2022
"Lasik was not something that i ever thought would be an option as it never was for my astigmatism and far sighted vision issues. New technology made something i never thought possible a possibility. This was the easiest thing ever. From what i expected was that it was suppose to be a slow progression and will continue to improve over next 6 weeks. I am already mind blown by how it has gone and how well I see. No glasses and I see better than I ever did with glasses...lol. Best Doctor, team, and experience. I HIGHLY Recommend everyone using Chu Vision Institute for all ete care needs. You will not regret it. Thank you!"- J.D. / Google / Mar 31, 2022
"From the day I walked in for my consult to the day after surgery and my first post-op, Chu Vision provided nothing short of a stellar experience. After 30 years of my life spent wearing glasses and 27 years with contacts, my vision stabilized and I was referred to Chu Vision. LASIK has been something I've wanted for many years but will be the first to admit my gut was wrenching with anxiety the entire month leading to the procedure after weighing the pros and cons of eye surgery. Browsing the internet and learning about side effects: glares, halos, starbursts...didn't exactly help my anxiety. Don't get me wrong, without glasses or contacts, I could barely make out the big E in the eye doctor's office. If anyone broke into my house, if a contact fell out while swimming, if something happened to my contacts/glasses on vacation...I'd be screwed. I wanted to be free. My 1:1 prior to surgery with Dr. Chu definitely put me at ease. The entire staff at Chu Vision is extraordinary...something you wish for at any service-related business. They calmed my nerves, walked through every step, answered all my questions, advised me how to prepare and what to truly expect afterward. The day of surgery was quick and absolutely painless...no pain at all, and my entire time at the office was 45 minutes. The actual procedure was less than 10 minutes. Dr. Chu provided an amazing surgery and turned my -6.75 prescription WITH ASTIGMATISM to 0!!!! The day after surgery for my post-op, I could easily see 20/20, and I know they don't guarantee better than 20/20, but I was able to see 20/15 the day after surgery, with my own eyes...truly amazing!!!! TO THIS DAY I CATCH MYSELF IN AMAZEMENT BECAUSE I KNOW WHAT IT WAS LIKE TO NOT HAVE THIS VISION WITH MY OWN EYES. I'm now 4.5 weeks out from when I had surgery and the post-op procedures and drops are cake. I have not had ANY glares, halos, starbursts, nothing. I can see clearly at night and during the day. "Whereas once I was blind, now I see." Thank you so much Dr. Chu, your team, and the experience you have built. I can't put into words how you have changed my life. Thank you so much."- C.K. / Google / Jan 20, 2022
"I had cataract surgery and before surgery had cloudy vision and a great deal of difficulty with night driving-halos, difficulty seeing lines on the roads especially on wet roads. I got the light adjusted lenses. It took a few weeks of adjustments but now I can see clearly to read and drive without glasses and the best part is I can drive at night and I don’t have the haloes around lights with oncoming traffic and I can see the road and lines even in the rain!! No glasses needed!!! I wear regular sunglasses in the sun but no prescriptions. Thanks Dr. Chu!!! Your staff was amazing-each person was polite and friendly and professional!"- L.F. / Google / Jun 04, 2022

Best Candidates for iStent
The iStent can be used in patients who have both cataracts and glaucoma. However, patients who have open-angle glaucoma typically attain the best outcomes. If you have been diagnosed with glaucoma and would like to find out if you qualify for the iStent, we recommend scheduling a visit at Chu Vision Institute. During an in-depth consultation, Dr. Chu will examine your vision and review your medical history and vision needs to determine if you would make a good candidate for treatment.
How Do You Implant the IStent?
Implantation of the iStent is an outpatient procedure at our accredited surgery center conveniently located just adjacent to Chu Vision Institute. This procedure is often carried out at the same time as cataract surgery. Prior to beginning your surgery, we will fully numb your eye and give you a mild sedative to keep you comfortable. If performed during cataract removal, Dr. Chu will utilize the same small incision to implant the tiny iStent device. He will use a specialized surgical tool to inject the iStent into your trabecular meshwork to encourage the flow of aqueous fluid from your eye, which helps decrease intraocular pressure. This procedure has given many of our patients the freedom to rely less on glaucoma medications and prescription eye drops.
What to Expect After Surgery
We will prescribe medications that you will need to take for the next several weeks after surgery. The medications will help prevent eye infections and inflammation so it is important to take them as prescribed. Dr. Chu or a member of our professional team will provide you with any other instructions for post-surgical care. Additionally, it is critical that you attend any required follow-up visits at Chu Vision Institute so we can monitor your intraocular pressure and make sure your healing is progressing well. We encourage you to contact our office if you have any questions regarding your home care following your surgery.
envision Your iStent Treatment
If you have glaucoma, there is hope for the future. Thanks to new innovations in ocular technology, it is now possible to live life without the constant glaucoma symptoms caused by a damaged optic nerve. Dr. Chu can implant the revolutionary iStent device to help control your glaucoma so you can get back to your daily routine. Contact Chu Vision Institute in Bloomington, MN to book your appointment, and find out if you qualify for the iStent or other minimally invasive glaucoma surgeries (MIGS).
