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.
"Where to even begin. I had been eagerly anticipating laser vision correction for at least 5 years but life continued to get in the way. I finally was in a position to move forward and found Dr. Chu and his practice upon moving to MN. I honestly do not have the words to express how thoroughly satisfied I am and continue to be with the entire experience. From the initial evaluation to the expert guidance, seamless follow up appointments, excellent communication, wonderful and friendly staff, truly knowledgeable physicians and providers who take the time to answer your questions, I could not be more pleased. I had initially wanted to have SMILE performed but, through the counsel of Drs. Heckman and Chu, underwent ASA with phenomenal results (and the vision continues to sharpen daily which is such an amazing thing to experience). Dr. Chu was able to take my vision from 20/500 (mostly from extremely severe astigmatism with coincident myopia) to 20/20. Most importantly, I was seeing 20/30 in my right eye the day following surgery and 20/20 by the 3-day follow up. At the risk of making this review too lengthy, I have to pay my respect not only to Dr. Chu's practice but to all the individuals who work there. From Dr. Hassan to Dr. Hampton, surgical intake nurses and all the techs, they legitimately made me feel like family. More than that, the work performed at this facility is second to none. I have already referred several colleagues for vision correction at Chu Vision. To top it off, Dr. Chu is honestly a stand up guy with some pretty amazing extracurriculars :) To anyone I may have missed, THANK YOU! Genuinely changing lives for the better. TL;DR - If you care about your eyes and want high-quality, complete care, look no further than Chu Vision. You will not be disappointed."- N.A. / Google / Aug 04, 2022
"I’m absolutely astounded at how instantly my vision was improved! I’ve gone from needing glasses for everything to having 20/20 vision again! I’m rather hesitant when it comes to needing anything medical. And now I want to tell everyone how incredible Dr Chu and his team are. From the folks helping to check you in to the kind and caring support on each and every visit, this has been my best experience EVER! Thank you to Nic, Asha and the research team, to all the Drs and the surgical team and to Dr Chu for believing in making a difference For ALL your eye needs, big or small, there is only one place you want to be. Chu Vision institute. Best decision I have made."- S.K. / Google / Sep 09, 2022
"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
"Dr. Chu did a wonderful job with my SMILE procedure, taking my -5.75 and -6 prescriptions to 20/20. My results are amazing, yes... but I think that being as nervous as I was, the thing that really made this experience phenomenal was the care that Dr. Chu, Dr. Heckman, and the whole team provided. I appreciate that they took the time to talk to me about all of my concerns before I scheduled my procedure - have really dialed in the actual day of your appointment so it's smooth and efficient and you always know what's going on and what to expect - and that they have continued to provide that level of care at every follow up appointment. I have always received such a warm welcome every time I have visited, and am grateful that they always find time to address any questions or concerns. PS - a special thank you to every technician I've been fortunate enough to meet at my appointments, you all provided such lovely, friendly conversation!"- N.M. / Google / Jun 28, 2022
"Can't speak highly enough about the results and experience I had with Dr. Chu and his team. After a Lasik procedure I have 20/20 vision. I was obviously a little concerned about having someone mess around with my eyeball with a laser... but the whole team at Chu Vision made me feel comfortable with the procedure and recovery and ensured I felt supported at every step. The procedure was a breeze - Dr. Chu has a great bedside manner and made me feel comfortable I was in good hands. Recovery was straightforward and it's now a full month that I've had great vision and not had to worry about corrective lenses. If you're considering refractive surgery with Chu, do it. My only regret is that I didn't do this sooner."- B.A. / Google / Aug 03, 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).
