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.
"Today after years of waiting to get LASIK I took the leap. Terrified as I was, all of the wonderful staff was amazing and kind. Dr. Chu talked me through the whole procedure, which is honestly an outstanding experience. I could not recommend Chu Vision Institute any higher! Perfect 10 :)"- M.B. / Yelp / May 04, 2021
"I came in for a Lasik consultation and Chu Vision is a well-oiled machine! Very organized and have the process of the exam and consultation down to a T. Everyone I encountered was very friendly! From the young man who checked me in at my vehicle, the exam and all the way to the end when I met with Amy Ray about scheduling and financing for Lasik. Love it and can't wait to put my eyes in your hands and get Lasik (spoiler...I'm an ideal candidate and will for sure be going to Chu Vision Institute)"- A.S. / Office Visit / Jul 14, 2021
"I had LASIK at Chu Vision last week and couldn’t recommend them highly enough. They provided a great consultation and advised on the best procedure for my eyes. Every detail (large and small) was planned for, and the whole process was very smooth. Best investment I’ve ever made!"- J.M. / Google / Apr 26, 2021
"I felt anxious at the pre op screening visit because I didn't understand how long the measuring process would take. Did I not ask enough questions? Did I not understand the explanations of the procedure? I'm not sure. But once I voiced my concern everything was explained to my complete understanding. The facility met or exceeded all the COVID protocols. It was close to home -- easy to access and had free parking. Dr. Chu was approachable and caring. Dr. Heckman was patient, caring and concerned about me as well as making sure Dr. Chu received the specs he needed to perform perfect surgery. THANK YOU!!!!"- N.C. / Office Visit / Jun 24, 2021
"I had LASIK performed by Dr. Chu and the entire experience was wonderful. All of the staff members were extremely nice and helpful - from the check in person who coordinated my visit to the tech who explained what all of the tests were and why they were needed during my evaluation appointment. Dr. Chu personally has a web call with you a few days before your surgery to ensure you do not have any other questions and are still comfortable with moving forward. The day of the surgery, Dr. Chu checks in with you right before you enter the laser room, performs the surgery himself, and then follows up immediately after by looking at your eyes to ensure everything went well. Chu Institute isn't the cheapest LASIK option, but it is clear why they are viewed as a leader in this field throughout the nation. From the knowledge and professionalism of the staff, to the attention that is received from Dr. Chu himself, to the best and latest technology to ensure the optimal results for your vision, they are worth the little extra. I personally wouldn't want my procedure done through a Groupon on a 10 year old laser system - your eyes are worth more than that."- P.P. / Google / Mar 11, 2021
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.

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.
